Gallbladder Cancer
Your gallbladder is a pear-shaped organ under your liver. It stores bile, a fluid made by your liver to digest fat. As your stomach and intestines digest food, your gallbladder releases bile through a tube called the common bile duct. The duct connects your gallbladder and liver to your small intestine.
Cancer of the gallbladder is rare. It is more common in women and Native Americans. Symptoms include
Jaundice (yellowing of the skin and whites of the eyes)
Pain above the stomach
Fever
Nausea and vomiting
Bloating
Lumps in the abdomen
It is hard to diagnose gallbladder cancer in its early stages. Sometimes doctors find it when they remove the gallbladder for another reason. But people with gallstones rarely have gallbladder cancer. Because it is often found late, it can be hard to treat gallbladder cancer. Treatment options include surgery, chemotherapy, radiation, or a combination.

Navigating the Clinical Trails Maze: Gallbladder Cancer
Gallbladder cancer is a rare type of cancer that starts in the tissues of the gallbladder.
Signs and symptoms of gallbladder cancer include jaundice, fever, and pain.
Gallbladder cancer is difficult to detect (find) and diagnose early.
Tests that examine the gallbladder and nearby organs are used to detect (find), diagnose, and stage gallbladder cancer.
Certain factors affect the prognosis (chance of recovery) and treatment options.
Gallbladder cancer is a rare type of cancer that starts in the tissues of the gallbladder.
Gallbladder cancer occurs when cells in the gallbladder start to grow out of control. The gallbladder is a pear-shaped organ that lies just under the liver in the upper abdomen. The gallbladder stores bile, a fluid made by the liver to digest fat. When food is being broken down in the stomach and intestines, bile is released from the gallbladder through a tube called the common bile duct, which connects the gallbladder and liver to the first part of the small intestine.
Anatomy of the gallbladder. The gallbladder is just below the liver. Bile is stored in the gallbladder and flows through the cystic duct and the common bile duct into the small intestine when food is being digested.
The wall of the gallbladder has 4 main layers of tissue:
mucosal (inner) layer
muscle layer
connective tissue layer
serosal (outer) layer
Primary gallbladder cancer starts in the inner layer and spreads through the outer layers as it grows.

Eye with Yellow Conjunctiva, Jaundice
When damaged or dying red blood cells are broken down in the spleen, bilirubin, a yellow pigment and component of hemoglobin, is released into the bloodstream. The waste bilirubin is usually efficiently eliminated from the body by the liver (the pigmented waste becomes a component of bile, which is stored in the gallbladder and released into the duodenum of the small intestine to aid in digestion). Various diseases of the liver or bile ducts, however, can result in the accumulation of bilirubin in the body, causing jaundice, a yellowing of the skin and whites of the eyes.

Diagnosis of Gallbladder Cancer
Gallbladder cancer is difficult to detect (find) and diagnose early.
Gallbladder cancer is difficult to detect and diagnose for the following reasons:
There are no signs or symptoms in the early stages of gallbladder cancer.
The symptoms of gallbladder cancer, when present, are like the symptoms of many other illnesses.
The gallbladder is hidden behind the liver.
Gallbladder cancer is sometimes found when the gallbladder is removed for other reasons. Patients with gallstones rarely develop gallbladder cancer.
Tests that examine the gallbladder and nearby organs are used to detect (find), diagnose, and stage gallbladder cancer.
Procedures that make pictures of the gallbladder and the area around it help diagnose gallbladder cancer and show how far the cancer has spread. The process used to find out if cancer cells have spread within and around the gallbladder is called staging.
In order to plan treatment, it is important to know if the gallbladder cancer can be removed by surgery. Tests and procedures to detect, diagnose, and stage gallbladder cancer are usually done at the same time. The following tests and procedures may be used:
Physical exam and health history: An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
Liver function tests: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by the liver. A higher than normal amount of a substance can be a sign of liver disease that may be caused by gallbladder cancer.
Blood chemistry studies: A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease.
CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the chest, abdomen, and pelvis, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. An abdominal ultrasound is done to diagnose gallbladder cancer.
PTC (percutaneous transhepatic cholangiography): A procedure used to x-ray the liver and bile ducts. A thin needle is inserted through the skin below the ribs and into the liver. Dye is injected into the liver or bile ducts and an x-ray is taken. If a blockage is found, a thin, flexible tube called a stent is sometimes left in the liver to drain bile into the small intestine or a collection bag outside the body.
ERCP (endoscopic retrograde cholangiopancreatography): A procedure used to x-ray the ducts (tubes) that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine. Sometimes gallbladder cancer causes these ducts to narrow and block or slow the flow of bile, causing jaundice. An endoscope (a thin, lighted tube) is passed through the mouth, esophagus, and stomach into the first part of the small intestine. A catheter (a smaller tube) is then inserted through the endoscope into the bile ducts. A dye is injected through the catheter into the ducts and an x-ray is taken. If the ducts are blocked by a tumor, a fine tube may be inserted into the duct to unblock it. This tube (or stent) may be left in place to keep the duct open. Tissue samples may also be taken.
MRI (magnetic resonance imaging) with gadolinium: A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
Endoscopic ultrasound (EUS): A procedure in which an endoscope is inserted into the body, usually through the mouth or rectum. An endoscope is a thin, tube-like instrument with a light and a lens for viewing. A probe at the end of the endoscope is used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. This procedure is also called endosonography.
Laparoscopy: A surgical procedure to look at the organs inside the abdomen to check for signs of disease. Small incisions (cuts) are made in the wall of the abdomen and a laparoscope (a thin, lighted tube) is inserted into one of the incisions. Other instruments may be inserted through the same or other incisions to perform procedures such as removing organs or taking tissue samples for biopsy. The laparoscopy helps to find out if the cancer is within the gallbladder only or has spread to nearby tissues and if it can be removed by surgery.
Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The biopsy may be done after surgery to remove the tumor. If the tumor clearly cannot be removed by surgery, the biopsy may be done using a fine needle to remove cells from the tumor.

Liver Function Tests
Liver Function Tests
Also called: Liver Panel, Liver Function Panel, Liver Profile, Hepatic Function Panel
Liver function tests are blood tests that measure different enzymes, proteins, and other substances made by the liver. Abnormal levels of any of these substances can be a sign of liver disease.
Liver Function Tests
Also called: Liver Panel, Liver Function Panel, Liver Profile, Hepatic Function Panel
Liver function tests are blood tests that measure different enzymes, proteins, and other substances made by the liver. Abnormal levels of any of these substances can be a sign of liver disease.
Liver function tests (also called a liver panel) use a sample of your blood to measure several substances made by your liver.
The most common liver function tests measure:
Albumin, a protein made in the liver.
Total protein. This test measures the total amount of protein in your blood, which includes albumin and globulins. These proteins are mainly made in your liver.
ALP (alkaline phosphatase), ALT (alanine transaminase), AST (aspartate aminotransferase), and GGT (gamma-glutamyl transferase). These are enzymes that are mainly made in your liver. Enzymes are proteins that speed up certain chemical reactions in your body.
Bilirubin, a waste product your body makes when it breaks down old red blood cells. Your liver removes most of the bilirubin from your body.
Lactate dehydrogenase (LDH), an enzyme found in most of the tissues in your body, but some of the largest amounts are found in your liver.
Prothrombin time (PT), how long it takes your blood to clot. Prothrombin is a protein involved in blood clotting. It's made in your liver.
Some of these tests can show how well your liver is working and others can show whether your liver may be damaged by liver disease or injury. But liver function tests alone usually can't diagnose specific diseases. So, if your results are abnormal, you'll usually need other tests to find the exact cause.
Other names: liver panel, liver function panel, liver profile hepatic function panel, LFT
Liver function tests are most often used to help:
Find out if liver disease or damage could be causing certain symptoms
Learn how serious liver disease is after it has been diagnosed
Monitor liver disease over time and/or find out how well treatment is working
Check for side effects of certain medicines that can affect the liver
Many liver function tests are included in a common blood test called a comprehensive metabolic panel (CMP). Your provider often orders a CMP as part of your routine checkup to screen for liver and other diseases.
You may also need liver function tests if you have symptoms of liver disease or damage. These include:
Nausea and vomiting
Lack of appetite
Fatigue
Weakness
Jaundice, a condition that causes your skin and eyes to turn yellow
Even if you don't have symptoms, you may need to be tested if you have a high risk for liver damage. Your risk may be high if you have:
A family history of liver disease
Alcohol use disorder (AUD)
Obesity
Diabetes
Been taking certain medicines that may cause liver damage
Hepatitis or have been exposed to hepatitis (swelling of the liver from infection or injury)
If you already have liver disease, you may need to be tested to monitor your condition and/or to see how well your treatment is working.
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
Your provider will tell you how to prepare for your test. You will probably need to fast (not eat or drink) for 10-12 hours before the test. Certain medicines can affect your test results, so be sure to tell your provider about everything you take. But don't stop taking any medicines unless your provider tells you to.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
Understanding abnormal liver function test results is often complicated. So, it's best to ask your provider to explain what your results say about your health.
If any of your liver function test results are abnormal, your provider will compare the results of all the substances that were measured. This is done to look for certain patterns of normal and abnormal results that suggest different types of liver conditions.
In general, the results of your liver function tests can tell you if:
Your liver is inflamed, which means you have hepatitis.
You have hepatitis from drinking alcohol or other causes, such as infection.
Your liver isn't working well and how weak it has become.
You have a problem with your bile ducts. Bile is a digestive "juice" that your liver makes. Bile ducts are the tubes that carry bile through your liver and out of your liver.
Medicines are harming your liver and how serious the damage is.
Abnormal results don't always mean you have a problem with your liver. Other conditions can cause high or low levels of certain substances that these tests measure. For example, high levels of ALP can be a sign of bone disease or liver disease. So, your provider will also consider your symptoms, medical history, risk for liver disease, and any medicines you take.
If you have been ill recently, certain types of abnormal results may be temporary. In this case, your provider may repeat the tests later to see if your results return to normal.

Enlarged Liver, a Sign of Hemochromatosis
Enlarged Liver, a Sign of Hemochromatosis : Hemochromatosis is a genetic disease that causes the body to absorb too much iron. Because the body can't use or eliminate this extra iron, it's stored in organs, especially the liver, but also the heart and pancreas. Eventually, up to 20 times as much iron as normal can accumulate, which can lead to organ failure. Symptoms can include irregular heartbeat, cirrhosis, chronic fatigue, confusion, and hepatomegaly, the enlargement of the liver.

Liver function is typically evaluated by a panel of tests, including one for alanine aminotransferase (ALT), an enzyme made in liver cells, that help doctors distinguish among the many different possible causes of liver damage. Alcoholic liver disease is linked to the length of time alcohol is consumed, as well as quantity, though not all heavy drinkers develop it; genetics and sex also play roles. Symptoms include liver inflammation, enlargement, and eventually scarring (cirrhosis).

Liver
The liver is a vital organ that has a wide range of functions; a few of which are detoxification, protein synthesis and production of biochemicals necessary for digestion. It is the largest organ in the body and is critical to one's health. Some of the most common conditions involving damage to the liver include alcoholic liver disease, cirrhosis, and hepatitis. The liver's general role is in the body's metabolism, secreting hormones that moderate the storage and breakdown of sugar. Glucose is the body's form of energy gleaned from carbohydrates, and it is stored in body cells as glycogen until the liver determines it is needed. At this point, the liver secrets glucagon, a hormone that will signal to cells to convert glycogen into its usable form, glucose.

Albumin is the most abundant protein in the body. It is made by the liver and plays many important roles, including maintaining pressure in the blood vessels and transporting substances, such as hormones and medications.
Related conditions
An albumin blood test measures the amount of albumin in your blood. Albumin is a protein made by your liver. Low albumin levels can be a sign of liver or kidney disease or another medical condition. High levels may be a sign of dehydration.
Blood is made of fluid and blood cells. Albumin keeps the fluid part of your blood from leaking out of your blood vessels (the tubes your blood flows through) and into other tissues. If you don't have enough albumin, fluid can leak out of your blood and build up in your lungs, abdomen (belly), or other parts of your body.
Albumin also helps carry important substances throughout your body. These include hormones, vitamins, and enzymes (proteins that speed up certain chemical reactions in your body).
Other names: ALB, serum albumin test
An albumin blood test is used to check your general health and nutrition, and to see how well your liver and kidneys are working. If your liver is damaged or you're not well nourished, your liver may not make enough albumin. If your kidneys are damaged, they may let albumin pass from your blood into your urine (pee).
An albumin test may also be used to monitor treatment for liver or kidney conditions, or other conditions that may affect albumin levels.
An albumin blood test is often done as part of a group of blood tests that measure different enzymes, proteins, and other substances made in your liver. These tests are called liver function tests or a liver panel. An albumin test may also be part of a comprehensive metabolic panel (CMP), a group of routine blood tests that measures 14 substances in a sample of your blood.
Your health care provider may order an albumin test as part of your routine checkup. In this case, the test is usually ordered as part of a group of liver function tests or a comprehensive metabolic panel.
You may also need an albumin test if you have symptoms of liver or kidney disease. Symptoms of liver disease include:
Nausea and vomiting
Lack of appetite
Fatigue
Weakness
Jaundice, a condition that causes your skin and eyes to turn yellow
With some types of kidney disease, such as chronic kidney disease, you may not have symptoms until the later stages.
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
You don't need any special preparations to test for albumin in blood. If your provider ordered other blood tests, you may need to fast (not eat or drink) for several hours before the test. Your provider will let you know if there are any special instructions to follow. Certain medicines may affect your test results, so tell your provider what you are taking. But don't stop taking any medicines without talking with your provider first.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
An albumin blood test alone cannot diagnose a condition. Your provider will usually consider your albumin test results with the results of other tests to make a diagnosis.
Lower than normal albumin levels in your blood may be a sign of:
Liver disease, including severe cirrhosis, hepatitis, and fatty liver disease
Kidney disease
Malnutrition, especially a lack of protein in your diet
Infection
Digestive diseases that involve problems using protein from food, such as Crohn's disease and malabsorption disorders
Burns over a large area of your body
Thyroid disease
Higher than normal albumin levels in your blood may be a sign of dehydration, which may be caused by severe diarrhea or other conditions.
If your albumin levels are not in the normal range, it doesn't always mean you have a medical condition that needs treatment. Certain medicines, including steroids, insulin, and hormones, can increase albumin levels. Your albumin levels may be lower than normal if you haven't eaten for 24 to 48 hours, or take certain medicines, including birth control pills. Albumin levels are also lower during pregnancy.
If you have questions about your test results, ask your provider to explain what they mean.

Healthy vs Damaged Kidney
A healthy kidney doesn’t let albumin pass into the urine. A damaged kidney lets some albumin pass into the urine.
Urine Test for Albumin
If you are at risk for kidney disease, your provider may check your urine for albumin.
Albumin is a protein found in your blood. A healthy kidney doesn’t let albumin pass into the urine. A damaged kidney lets some albumin pass into the urine. The less albumin in your urine, the better. Having albumin in the urine is called albuminuria.
A diagram showing a healthy kidney with albumin only found in blood, and a damaged kidney that has albumin in both blood and urine.
A healthy kidney doesn’t let albumin pass into the urine. A damaged kidney lets some albumin pass into the urine.
A health care provider can check for albumin in your urine in two ways:
Dipstick test for albumin. A provider uses a urine sample to look for albumin in your urine. You collect the urine sample in a container in a health care provider’s office or lab. For the test, a provider places a strip of chemically treated paper, called a dipstick, into the urine. The dipstick changes color if albumin is present in the urine.
Urine albumin-to-creatinine ratio (UACR). This test measures and compares the amount of albumin with the amount of creatinine in your urine sample. Providers use your UACR to estimate how much albumin would pass into your urine over 24 hours. A urine albumin result of
30 mg/g or less is normal
more than 30 mg/g may be a sign of kidney disease
If you have albumin in your urine, your provider may want you to repeat the urine test one or two more times to confirm the results. Talk with your provider about what your specific numbers mean for you.
If you have kidney disease, measuring the albumin in your urine helps your provider know which treatment is best for you. A urine albumin level that stays the same or goes down may mean that treatments are working.

Electrophoresis - concentration - Albumin
The albumins (formed from Latin: albumen \"(egg) white; dried egg white\") are a family of globular proteins, the most common of which is serum albumin. The albumin family consists of all proteins that are water-soluble, are moderately soluble in concentrated salt solutions, and experience heat denaturation. Albumins are commonly found in blood plasma, and are unique from other blood proteins in that they are not glycosylated. Substances containing albumins, such as egg white, are called albuminoids. A number of blood transport proteins are evolutionarily related, including serum albumin, alpha-fetoprotein, vitamin D-binding protein and afamin.

Albumin, Kidney Disease
Proteins are normally filtered out of the blood and recycled by the kidneys, including the blood protein albumin, which is produced by the liver and helps maintain the fluid balance of blood as well as transport hormones, vitamins, and other substances throughout the body. When kidneys are diseased or damaged, however, their ability to filter out proteins is compromised, which allows proteins like albumin to then leak into urine.

Albumin: Kidney Disease
Kidney disease can result in abnormal albumin levels because diseased or damaged kidneys are not able to effectively filter out and recycle albumin in the blood; instead, albumin leaks into the urine.

Albumin: Blood Serum
The serum is the clear, liquid portion of the blood. There are two classes of proteins, albumin and globulin, found in the blood. Albumin is the most abundant protein; its main purpose is to keep fluid from leaking out of blood vessels.

An imbalance of albumins to globulins ratio gives insight into your nutritional status and immune function. The normal range for albumin/globulin ratio is approximately 1 to 2. That’s because there’s a bit more albumin than globulin in serum protein.
Related conditions
A total protein and albumin/globulin (A/G) ratio test measures the total amount of protein in your blood. There are two major types of protein in the blood:
Albumin, which helps keep blood from leaking out of blood vessels. It also helps move hormones, medicines, vitamins, and other important substances throughout the body. Albumin is made in the liver.
Globulins, which help fight infection and move nutrients throughout the body. Some globulins are made by the liver. Others are made by the immune system.
The test also compares the amount of albumin in your blood to the amount of globulin. The comparison is called the albumin/globulin (A/G) ratio.
If your total protein levels or A/G ratio results are not normal, it can be a sign of a serious health problem.
A total protein and A/G ratio test is often included as part of a comprehensive metabolic panel, a test that measures proteins and other substances in the blood. It may also be used to help diagnose kidney disease, liver disease, or nutritional problems.
You may get this test as part of a comprehensive metabolic panel, which is often included in a routine checkup. You may also need this test if you have symptoms that indicate abnormal protein levels. These include:
Swelling in the feet, ankles, legs, and/or abdomen, which is caused by extra fluid in your tissues
Fatigue
Unexplained weight loss
Loss of appetite
Nausea and vomiting
Jaundice (yellowing of the skin or eyes). This is a common symptom of liver disease.
Blood in the urine, a common symptom of kidney disease
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
You don't need any special preparations for a total protein and A/G ratio test.
There is very little risk to having a blood test. There may be slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
Your results will show whether you have normal, low, or high total protein levels. They will also show if you have a normal, low, or high albumin to globulin (A/G) ratio.
If your total protein levels were low, it may mean you have one of the following conditions:
Liver disease
Kidney disease
Malnutrition, a condition in which your body does not get the calories, vitamins, and/or minerals needed for good health
A malabsorption syndrome, a type of disorder in which your small intestine can't absorb enough nutrients from food. Malabsorption syndromes include celiac disease and Crohn's disease.
If your total protein levels were high, it may mean you have one of the following conditions:
An infection such as HIV or viral hepatitis
Multiple myeloma, a type of blood cancer
If your A/G ratio was low, it may be caused by:
An autoimmune disease, such as lupus
Liver disease, including cirrhosis
Kidney disease
If your A/G ratio was high, it may be caused by:
Certain types of genetic disorders
Leukemia
If you have questions about your results, talk to your health care provider.
In addition to total protein levels, your provider may order a separate blood test for albumin and/or a test for globulins. The globulins test is called serum electrophoresis. It is a blood test that measures the levels of four different types of globulins.
These results may show the following:
Low albumin levels may be a sign of:
Liver disease, including cirrhosis
Kidney disease
Malnutrition
Thyroid disease
High albumin levels may be a sign of:
Severe dehydration
Diarrhea
Low globulin levels may be a sign of:
Liver disease

ALP is an enzyme found throughout the body, but it is mostly found in the liver, bones, kidneys, and digestive system. When ALP leaks into the bloodstream it may be a sign of a serious health issue.
Related conditions
An alkaline phosphatase (ALP) test measures the amount of ALP in your blood. ALP is an enzyme, a protein that speeds up certain chemical reactions in your body. ALP is found in all your body tissues, but higher amounts can be found in your liver, bile ducts, and bones. Each part of your body makes a different type of ALP.
Abnormal levels of ALP in your blood may be a sign of a wide range of health conditions, including liver disease, bone disorders, and chronic kidney disease. The amount of ALP released into your blood can be affected by liver damage, conditions that affect bone growth, and certain gastrointestinal diseases. But an alkaline phosphatase test alone can't identify the source of ALP in your blood, so other tests are usually needed to make a diagnosis.
Other names: ALP, ALK, PHOS, Alkp, ALK PHOS
An alkaline phosphatase test is often used to screen for or help diagnose diseases of the liver or bones. The test may also help diagnose or monitor other health conditions.
Your health care provider may order an alkaline phosphatase test as part of a routine checkup. Many conditions may affect ALP levels, so the test is often done with other blood tests. These other tests can include a comprehensive metabolic panel (CMP) or liver function tests, which check how well your liver is working.
An alkaline phosphatase test may also be ordered if you have symptoms of liver damage or a bone disorder.
Symptoms of liver disease can include:
Nausea and vomiting
Lack of appetite
Fatigue
Weakness
Jaundice, a condition that causes your skin and eyes to turn yellow
An alkaline phosphatase test is a type of blood test. During the test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
Your provider will let you know if there are any special instructions. An ALP test is usually ordered with other blood tests. You usually need to fast (not eat or drink) for several hours before these tests.
You may need to stop taking certain medicines before the test, so tell your provider about everything you take. But don't stop taking any medicines unless your provider tells you to.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
High alkaline phosphatase (ALP) levels may be a sign of a liver problem or a bone disorder. Liver problems and bone disorders create different types of ALP. But your ALP test results can't tell which type of ALP is high.
If your test results show high ALP levels, your provider may order other tests to help figure out what's causing the problem. These tests may include:
An ALP isoenzyme test. This test can tell which part of your body is making the ALP. But this test may not be available everywhere.
Liver function tests. If the results of these tests are also high, then your high ALP level is likely from a problem in your liver.
High alkaline phosphatase levels from your liver may be a sign of:
Blockages in your bile ducts
Cirrhosis
Hepatitis
Mononucleosis, which can sometimes cause swelling in the liver
If alkaline phosphatase levels are high and the results of liver tests are normal, the problem may be a bone disorder, such as Paget's disease of bone. This disease makes your bones unusually large and weak, causing them to break more easily.
Moderately high levels of ALP may be a sign of many different types of conditions, including:
Hodgkin lymphoma
Heart failure
Certain infections
It's possible to have higher than normal levels of ALP and not have a medical condition that needs treatment. Your provider will consider your symptoms, medical history, and other test results to make a diagnosis.
Low levels of ALP are less common. They may be a sign of:
Zinc deficiency
Protein deficiency
Malnutrition
Pernicious anemia
Thyroid disease
Wilson disease
Hypophosphatasia, a rare genetic disease that affects bones and teeth
Many things can affect ALP levels. For example:
Pregnancy can cause higher than normal ALP levels.
Children and teens may have high levels of ALP because their bones are growing.
Birth control pills and certain medicines may lower ALP levels, while other medicines can cause the levels to increase.
Eating a fatty meal before an alkaline phosphatase test may also cause a small increase in ALP.
To learn what your results mean, talk with your provider.

Alkaline Phosphatase Test
Alkaline phosphatase (ALP) is an enzyme made in liver cells. Elevated levels of ALP can be caused by many types of liver damage, including hepatitis, cirrhosis, liver cancer or drug toxicity. Heart bypass surgery or blood transfusions can cause temporary drops in ALP; persistently low levels of ALP may be caused by zinc deficiency or a rare genetic bone disorder.

Alkaline Phosphatase, Liver
The liver is the body's central chemical plant, filtering blood and removing toxins, storing sugars, lipids, and vitamins, and producing important blood proteins. Liver function is typically evaluated by a panel of tests, including one for alkaline phosphatase (ALP), an enzyme made in liver cells, that help doctors distinguish among the many different possible causes of liver damage. Many types of liver damage, including hepatitis, cirrhosis, liver cancer or drug toxicity, can elevate ALP levels.

Bilirubin, Gallbladder
When damaged or dying red blood cells are broken down, bilirubin, a yellow pigment and component of hemoglobin, is released into the bloodstream. Bilirubin is eliminated from the body by the liver as a component of bile, which is stored in the gallbladder and then released into the small intestine to aid digestion.
Image by TheVisualMD
Alkaline Phosphatase Test for Bone Growth
In bone, alkaline phosphatase (ALP) is produced by the cells (called osteoblasts) that are responsible for bone formation, which is why the test can be used to diagnose Paget's disease or detect cancers that have spread to the bone, both of which raise ALP blood levels. Alkaline phosphatase (ALP) is an enzyme made in liver cells. Children and adolescents normally have higher blood ALP levels because their bones are still growing and levels of the enzyme can spike during growth spurts. Fetal bone growth is the reason that pregnancy can elevate ALP blood levels, particularly in the 3rd trimester.

ALT, or alanine aminotransferase, is one of the two liver enzymes. It is a protein made only by liver cells. When ALT leaks out into the bloodstream it indicates that liver cells are damaged.
Related conditions
An ALT test measures the amount of ALT in your blood. This test is commonly used to help diagnose liver damage or disease.
ALT (alanine transaminase) is an enzyme, a protein that speeds up certain chemical reactions in your body. It is found mainly in your liver. Usually, you will have low levels of ALT in your blood. But when liver cells are damaged, they release ALT into the bloodstream. High levels of ALT in your blood may be a sign of a liver injury or disease. Some types of liver disease cause high ALT levels even before you have symptoms of the disease. So, an ALT blood test may help diagnose certain liver diseases early, when they may be easier to treat.
An ALT test is usually ordered as part of a group of liver function tests.
An ALT blood test is often part of a routine blood screening to check the health of your liver. The test may also help diagnose or monitor liver problems.
Your health care provider may order an ALT blood test as part of a routine checkup. An ALT test is usually done with a group of other liver function tests that check how well your liver is working. Many liver function tests are included in a common blood test called a comprehensive metabolic panel (CMP).
These tests may also be ordered if you have symptoms of liver damage, such as:
Nausea and vomiting
Lack of appetite
Fatigue
Weakness
Jaundice, a condition that causes your skin and eyes to turn yellow
Your provider may also order an ALT blood test if you have a high risk of liver damage because of:
A family history of liver disease
Alcohol use disorder (AUD)
Obesity
Diabetes
Taking certain medicines that can cause liver damage
Hepatitis or exposure to hepatitis
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
You may need to stop taking certain medicines before the test, so tell your provider about everything you take. But don't stop taking any medicines unless your provider tells you to.

There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
An ALT blood test is often done as part of a group of liver function tests. Liver function tests measure several different proteins, substances, and enzymes that show how well your liver is working. Your provider usually compares your ALT results with the results of the other liver tests to evaluate your liver health and decide if you need other tests to make a diagnosis.
Lower-than-usual levels of ALT in your blood are not common. Your provider may do more tests since this may be a sign of:
B6 deficiency
Chronic kidney disease
Higher-than-usual levels of ALT in your blood may be a sign of liver damage from:
Hepatitis
Infection
Cirrhosis
Liver cancer
Other liver diseases
A lack of blood flow to the liver
Certain medicines, such as cholesterol or pain medicines
Poisons
If your results show you have a high level of ALT, it doesn't always mean that you have a medical condition that needs treatment. Many things can affect your results, such as your age, sex, weight, and certain medicines and dietary supplements. Your ALT levels can also be affected by intense exercise and where you are in your menstrual cycle.
To learn what your results mean, talk with your provider.
ALT test results may help tell the difference between damage from acute (sudden) liver problems and chronic (long-term) liver problems. But the amount of ALT in your blood isn't related to how much your liver may be damaged.
Your ALT is usually measured along with another liver enzyme called AST as part of a liver function panel. Since ALT is mostly found in the liver, an ALT test checks more specifically for liver damage.

AST, or aspartate aminotransferase, is one of the two liver enzymes. AST is a protein made by liver cells. AST is also found in parts of the body other than the liver—including the heart, kidneys, muscles, and brain. When AST leaks out into the bloodstream it means that cells in any of those parts of the body are damaged.
Related conditions
An AST blood test measures the amount of AST in your blood. This test is commonly used to help diagnose liver damage or disease.
AST (aspartate aminotransferase) is an enzyme, a protein that speeds up certain chemical reactions in your body. It is found mainly in your liver but also in your heart, muscles, and other tissues. Usually, you will have low levels of AST in your blood. When your liver or other cells that contain AST are damaged, they release AST into your blood. This can lead to high AST levels in your blood.
An AST test may be ordered by itself but is often ordered as part of a group of liver function tests.
Other names: SGOT test, serum glutamic oxaloacetic transaminase test; aspartate transaminase test
An AST blood test is often part of a routine blood screening to check the health of your liver. The test may help diagnose or monitor liver problems. It may also help diagnose other health conditions.
You may get an AST blood test as part of your routine checkup or to monitor the treatment of a liver problem. You may also need a test if you have symptoms of liver damage, which may include:
Nausea and vomiting
Lack of appetite
Fatigue
Weakness
Jaundice, a condition that causes your skin and eyes to turn yellow
Even if you don't have symptoms, your health care provider may order an AST blood test if you're more likely to develop liver disease because of:
A family history of liver disease
Alcohol use disorder (AUD)
Obesity
Diabetes
Taking certain medicines that can cause liver damage
Hepatitis or exposure to hepatitis
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
You may need to stop taking certain medicines before the test, so tell your provider about everything you take. But don't stop taking any medicines unless your provider tells you to.
An AST test is usually ordered with other blood tests. You usually need to fast (not eat or drink) for up to 12 hours before these tests. Your provider will let you know if there are any special instructions.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
Low levels of AST in the blood are usually considered normal.
High levels of AST in the blood may be due to liver disease or other liver problems. Other reasons you may have high levels of AST can include:
Hepatitis
Cirrhosis
Mononucleosis
Heart procedures or problems
Pancreatitis
Hemochromatosis (too much iron in the body)
Deep burns
Seizures
Use of drugs that are toxic to the liver, especially alcohol use
Surgery
If your results are not in the normal range, it doesn't always mean that you have a medical condition that needs treatment. Many things can affect your results, such as pregnancy, exercise, certain medicines, and your age or sex. Talk with your provider to learn what your results mean.
Your health care provider may order an ALT blood test along with your AST blood test. ALT stands for alanine transaminase, which is another type of liver enzyme. If you have high levels of AST and/or ALT, it may mean that you have some type of liver damage.

GGT is an enzyme found mainly in the liver and is normally present in low levels in the blood.
Related conditions
A gamma-glutamyl transferase (GGT) test measures the amount of GGT in your blood GGT is an enzyme. Enzymes are proteins that speed up certain chemical reactions in your body. Thousands of enzymes play an important role in all of your body functions. The GGT enzyme is found throughout your body, but it is mainly found in your liver.
If your liver or bile duct is damaged, GGT may leak into your bloodstream. So high levels of GGT in your blood may be a sign of liver disease or damage to the bile ducts. Bile ducts are tubes that carry bile in and out of the liver. Bile is a fluid made by the liver that is important for digestion.
A GGT test can't diagnose the specific cause of liver disease. The test can only indicate that your liver is being damaged. This test is usually done with or after other liver function tests, most often an alkaline phosphatase (ALP) test. ALP is another type of liver enzyme. While both your GGT and ALP may be elevated in diseases that affect your bile ducts and liver, only ALP will be elevated in bone disease. This helps your health care provider to understand if your issue may be due to a bone disorder instead of your liver.
Other names: gamma-glutamyl transpeptidase, GGTP, Gamma-GT, GTP
A GGT test is most often used to:
Help diagnose liver disease
Figure out if liver damage is due to liver disease or a bone disorder
Check for blockages in the bile ducts
Screen for or monitor alcohol use disorder (AUD). Drinking alcohol increases GGT levels. Most people with AUD have high GGT levels.
You may need a GGT test if you have symptoms of liver disease. They may include:
Fatigue
Weakness
Jaundice, a condition that causes your skin and eyes to turn yellow
Loss of appetite
Abdominal (belly) pain or swelling
Nausea and vomiting
Severe itching
Your provider may use this test to monitor your alcohol use if you're being treated for AUD. You may also need this test if you have abnormal results on an ALP test and/or other liver function tests.
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
Talk to your provider to see if there are any specific instructions, since. the results of your GGT test may be affected by:
Certain medicines or supplements
Drinking alcohol
Smoking cigarettes
GGT levels go down after meals. Your provider may also ask you to fast for a certain amount of time before testing.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
If your results show higher-than-normal levels of GGT, it may be a sign of liver damage. The damage may be due to one of the following conditions:
Hepatitis.
Cirrhosis.
Alcohol use disorder (AUD).
Pancreatitis.
Diabetes.
Heart failure.
Side effects of a medicine. Certain medicines can cause liver damage in some people.
The results can't tell you which condition is causing your liver damage, but they can help show how much damage there is. Usually, the higher the level of GGT, the more liver damage you have.
If your results show low or normal levels of GGT, you probably don't have liver disease.
Your results may also be compared with the results of an ALP test. ALP tests help diagnose bone disorders. Together, your results may show one of the following:
High levels of ALP and high levels of GGT mean your symptoms are likely due to a liver disorder and not a bone disorder.
High levels of ALP and low or normal GGT levels mean it's more likely you have a bone disorder.
If you have questions about your results, talk to your provider. Your provider will consider your symptoms, medical history, and the results of other blood tests to understand the results of your GGT test.
In addition to an ALP test, your provider may order liver function tests with or after the GGT test. These may include:
Alanine aminotransferase, or ALT
Aspartate aminotransferase, or AST
Lactic dehydrogenase, or LDH

A bilirubin blood test measures the levels of bilirubin in your blood. Bilirubin is a yellowish substance made during your body's normal process of breaking down old red blood cells. Bilirubin is found in bile, a fluid your liver makes to help you digest food.
If your liver is healthy, it will remove most of the bilirubin from your body through your bile ducts (the tubes that carry bile from your liver). If your liver is damaged or your bile ducts are blocked, bilirubin can leak out of your liver and into your blood. When too much bilirubin gets into the bloodstream, it can cause jaundice, a condition that causes your skin and eyes to turn yellow. If you have jaundice, your health care provider may order a bilirubin blood test to check for liver disease or damage.
Bilirubin is usually tested with a blood test but can also be tested in your urine.
Other names: Total serum bilirubin, TSB total bilirubin, TBIL neonatal bilirubin, direct bilirubin, conjugated bilirubin, indirect bilirubin, unconjugated bilirubin
A bilirubin blood test may be used to check the health of your liver, look for the cause of jaundice, or determine how well a treatment is working.
The test is also commonly used to help diagnose newborn jaundice. Many healthy babies get jaundice because their livers haven't developed enough to get rid of the bilirubin. Newborn jaundice is usually not harmful and clears up within a few weeks. But in some cases, high bilirubin levels can lead to brain damage, so infants are often tested as a precaution.
Your health care provider may order a bilirubin blood test:
If you have symptoms such as jaundice, dark urine, clay-colored stool (poop), or stomach pain. These could indicate hepatitis, cirrhosis, or other liver diseases.
To find out if there is a blockage in your bile ducts.
To monitor an existing liver disease.
To diagnose disorders related to your body breaking down red blood cells too quickly. For example, high bilirubin levels in the bloodstream may be a sign of hemolytic anemia. This condition happens when your body destroys red blood cells faster than it makes them.
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
If the test is done on your newborn, they will have a heel stick test. A health care professional will clean your baby's heel with alcohol and poke the heel with a small needle. They will collect a few drops of blood and put a bandage on the site.
Your provider may tell you to fast (not eat or drink) for several hours before your blood test. You may need to stop taking certain medicines before this test, so tell your provider about everything you take. But don't stop taking any medicines unless your provider tells you to. Your provider will let you know if there are any other special instructions.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
The results will show if the amount of bilirubin in your is in the normal range. The normal ranges can vary from lab to lab.
If the results are outside your lab's reference range, you may need further testing. Normal results can vary based on the lab, your sex, and if the test is being done on an infant or child. but high bilirubin levels may mean your liver isn't working right.
High bilirubin levels (hyperbilirubinemia) may be due to:
Hemolytic anemia
Liver disease
Blockage in your bile ducts
Low bilirubin levels (hypobilirubinemia) are not usually a cause for concern but may be due to:
Medicines such as antibiotics, birth control pills, sleeping pills, and seizure medicines
Abnormal results don't always mean you have a medical condition that needs treatment. Higher-than-normal bilirubin levels can also be caused by some medicines, certain foods, or strenuous exercise. To learn what your results mean, talk with your provider.
A bilirubin blood test is only one measure of your liver health. If your provider thinks you might have a liver disease or a red blood cell disorder, you may need other tests, such as:
Liver function tests, a group of tests that measure different substances in your blood
Liver protein tests
Urine tests
An ultrasound
A liver biopsy, to get a sample of your liver tissue to examine under a microscope

Bilirubin, Direct: Red Blood Cells
There are 20 to 30 trillion red blood cells circulating through the body of an adult. Individual red blood cells live about 100 days, which means that about 2 million die (and an equal number replaced) every second. Bilirubin is left behind after these older blood cells are removed.

Eye with Yellow Conjunctiva, Jaundice
When damaged or dying red blood cells are broken down in the spleen, bilirubin, a yellow pigment and component of hemoglobin, is released into the bloodstream. The waste bilirubin is usually efficiently eliminated from the body by the liver (the pigmented waste becomes a component of bile, which is stored in the gallbladder and released into the duodenum of the small intestine to aid in digestion). Various diseases of the liver or bile ducts, however, can result in the accumulation of bilirubin in the body, causing jaundice, a yellowing of the skin and whites of the eyes.

A lactate dehydrogenase (LDH) test usually measures the level of lactate dehydrogenase (LDH) in a sample of your blood. In certain cases, LDH levels are measured in samples of other body fluids. This includes testing fluid from the spine (cerebrospinal fluid), the belly (peritoneal fluid), and the chest (pleural fluid).
LDH is also called lactic acid dehydrogenase. It is an enzyme. An enzyme is a protein that speeds up certain chemical reactions in your body. LDH helps your cells make energy. It is found in almost all the tissues in your body. The largest amounts of LDH are found in your muscles, liver, kidneys, and red blood cells.
If disease or injury damages tissues that have LDH, their cells release the enzyme into your bloodstream or other body fluids. It's normal to have some LDH in your blood and body fluids. But if your LDH levels are high, it may be a sign of certain diseases or injuries.
An LDH test alone can't show what is damaging your tissues or where the damage is located. So, an LDH test is usually done with other types of tests that can help diagnose the problem.
Other names: LD test, lactic dehydrogenase, lactic acid dehydrogenase
LDH is mainly used to check for tissue damage. Many types of acute (sudden) and chronic (long-lasting) conditions can damage tissues and cause high LDH levels. So LDH testing may be used in many different situations from bone and muscle injuries to monitoring treatment for cancer. For example, an LDH test may be used to:
Help diagnose and/or monitor diseases that affect the:
Blood, including anemia
Liver
Lungs
Kidneys
Heart, including heart attack
Pancreas
Brain and spinal cord, such as encephalitis and bacterial meningitis
Help monitor conditions that may get worse over time, such as muscular dystrophy and HIV
Help diagnose certain severe infections
Find out how serious certain types of cancer may be, including multiple myeloma, lymphoma, leukemia, testicular cancer, and melanoma.
Check whether treatment for certain types of cancer is working
Because LDH testing is used for so many conditions, it's best to ask your health care provider why you need an LDH test. In general, the test is ordered if other tests and/or your symptoms suggest you have tissue damage or disease.
If you have a disease that affects LDH levels, you may need an LDH test to learn more about your condition and to find out if your treatment is helping.
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
If your provider thinks you have a condition that may affect LDH levels in other body fluids, you may have a procedure to get a fluid sample. These procedures may include:
A lumbar puncture or "spinal tap" to collect cerebrospinal fluid that flows around your brain and spinal cord
A thoracentesis to remove fluid in the chest
A paracentesis or "abdominal tap" to remove fluid from the abdomen
If you are having one of these tests, your provider will explain the procedure.
You don't need any special preparations for an LDH blood test. If your test uses other fluid samples, your provider will tell you how to prepare.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly. If you are having another type of test, your provider will explain the risks.
LDH testing is used for many reasons. The meaning of your LDH test results depends on the reason you had the test, your symptoms, and the results of other tests you've had. So, ask your provider to explain what your results say about your health.
In general, LDH levels that are higher than normal usually mean you have some type of tissue damage. The damage is usually from disease, infection, or injury. Your provider may order more tests to diagnose your condition.
But higher a than normal LDH level doesn't always mean you have a medical condition that needs treatment. High levels can be caused by intense exercise and certain medicines, including aspirin. It's also possible to have a high LDH level if many red blood cells broke open when your sample was collected and tested.
Lower than normal LDH levels aren't common and usually aren't considered to be a health problem. Taking large amounts of vitamin C or vitamin E may cause low levels. Low LDH levels may also be caused by a rare genetic disorder called lactate dehydrogenase deficiency.
If your results showed higher than normal LDH levels, your provider may order a more specific type of LDH test that can help find out where the LDH is coming from. This more specific test is called an LDH isoenzyme test.
An LDH isoenzyme test measures the levels of five different forms of LDH. This information helps your provider find out about the type of tissue that's damaged, where in the body it may be, and how serious the damage may be.

Ischemic Stroke
Ischemic Stroke: The illustration shows how an ischemic stroke can occur in the brain. If a blood clot breaks away from plaque buildup in a carotid (neck) artery, it can travel to and lodge in an artery in the brain. The clot can block blood flow to part of the brain, causing brain tissue death.

PT/INR
Prothrombin Time Test and INR
Also called: PT/INR, Prothrombin Time, Prothrombin Time/International Normalized Ratio, PT Protime, INR
A prothrombin time test (PT) measures the time it takes for a clot to form in a blood sample. An INR is a calculation based on the results of a PT test. A PT/INR test is used to see if your blood is clotting normally and if warfarin is effective in treating clotting disorders.

A prothrombin time (PT) test measures how many seconds it takes for a clot to form in a blood sample. Since the results of this test can vary with different labs or test methods, your results may be used to create an INR (international normalized ratio). Using this ratio makes it easier for health care providers to compare and better understand results from different labs or test methods.
Prothrombin is a protein made by the liver. It is one of several substances known as clotting (coagulation) factors. When you get a cut or other injury that causes bleeding, your clotting factors work together to form a blood clot. Blood clotting is an important process that prevents you from losing too much blood when you are injured. Clotting factor levels that are too low can cause you to bleed too much after an injury. Levels that are too high can cause dangerous clots to form in your arteries or veins.
A PT/INR test helps find out if your blood is clotting normally. It also checks to see if a medicine that prevents blood clots is working the way it should.
Other names: prothrombin time/international normalized ratio, PT, pro time
A PT/INR test is most often used to:
See how well warfarin, an anti-coagulant or blood-thinning medicine, is working to prevent blood clots. (Coumadin is a common brand name for warfarin.) Your provider may change your dose based on these results.
Find out the reason for abnormal blood clots.
Find out the reason for unusual bleeding.
Check clotting ability before a procedure or surgery that may cause bleeding.
Check for liver problems.
Check for vitamin K deficiency. Vitamin K helps with blood clotting.
A PT/INR test is often done along with a partial thromboplastin time (PTT) test. A PTT test also checks for clotting problems but looks at different coagulation factors than the PT test.
If you are regularly taking warfarin, you may need this test to make sure you are taking the right dose. Your provider will let you know how often you need to get the test to monitor your dose.
If you are not taking warfarin, you may need this test if you have symptoms of a bleeding or clotting disorder.
Symptoms of a bleeding disorder include:
Unexplained heavy bleeding
Bruising easily
Unusually heavy nose bleeds
Unusually heavy menstrual periods in women
Symptoms of a clotting disorder include:
Leg pain or tenderness
Leg swelling
Redness or darkening of the skin on the leg
Skin that feels warm
Trouble breathing
Cough
Chest pain
Rapid heartbeat and breathing
In addition, you may need a PT/INR test if you are scheduled for surgery. It helps make sure your blood is clotting normally, so you won't lose too much blood during the procedure.
The test may be done on a blood sample from a vein or a fingertip.
For a blood sample from a vein:
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.
For a blood sample from a fingertip:
A fingertip test may be done in a provider's office or in your home. If you have been taking warfarin for a long time, you may be trained to take your blood sample with an at-home testing kit. Your provider may recommend you test your blood regularly using an at-home PT/INR test kit. During this test, you or your provider will:
Use a small needle to puncture your fingertip.
Collect a drop of blood and place it onto a test strip or other special instrument.
Place the instrument or test strip into a device that calculates the results. At-home devices are small and lightweight.
If you are using an at-home test kit, you will need to review your results with your provider. Your provider will let you know how they would like to receive the results.
If you are taking warfarin, you may need to delay your daily dose until after testing. Your provider will let you know if there are any other special instructions to follow.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
If you were tested because you are taking warfarin or have certain health conditions, your results will probably be in the form of INR levels:
INR levels that are too low may mean you are at risk for dangerous blood clots because your blood clots too easily.
INR levels that are too high may mean you are at risk for dangerous bleeding because your blood is taking longer than normal to form a clot.
If your INR is not normal, your provider will probably change your dose of warfarin.
If you are not taking warfarin, your results may be in the form of a PT time, which is the number of seconds it takes for your blood sample to clot (prothrombin time).
If you are not taking warfarin and your INR or prothrombin time results are not normal, it may be a sign of that your blood is not clotting normally.
If your PT/INR levels are too low, your blood is clotting too quickly. This may be due to:
A clotting disorder, a condition in which your body forms too many clots in arteries or veins. Clots can form when you don't have an injury, or they don't dissolve when they should.
Supplements with vitamin K, or a diet high in vitamin K.
Certain medicines.
If your PT/INR levels are too high, your blood is clotting too slowly. This may be due to:
A bleeding disorder, a condition in which your body can't clot blood well. When you have an injury or a procedure that may cause bleeding, it may cause too much bleeding.
Liver disease.
Vitamin K deficiency. Vitamin K plays an important role in blood clotting.
Be sure to tell your provider if you are taking any medicines or supplements. Some may affect your results. Other things that may affect your PT/INR results include:
Alcohol
Foods high in vitamin K, such as green leafy vegetables
Soybean and canola oils
High-fat diets
Ask your provider what you should avoid before your PT/INR test.
To understand the results of a PT/INR test, your provider will consider your symptoms, medical history, and the results of other blood tests.
Sometimes certain liver tests are ordered along with a PT/INR test. These include:
Aspartate Aminotransferase (AST)
Alanine Aminotransferase (ALT)

Prothrombin Time (PT): Pulmonary Embolism
The most dangerous complication of deep vein thrombosis (DVT) is pulmonary embolism, which occurs when an embolism travels through the heart and into the lungs. There it lodges in an artery, typically where the artery forks, and blocks blood flow. During an episode of pulmonary embolism, the lungs may be showered with blood clots. The lungs are particularly vulnerable to embolisms because all the blood in the body passes through the lungs every time it circulates.

A laparoscopy is a type of surgery that lets a surgeon look inside your body without making a large incision (cut). It's used to help diagnose and sometimes treat conditions that develop in your belly or pelvis.
To do a laparoscopy, a surgeon makes a small cut near your belly button that's usually a half-inch long or less. The surgeon inserts a long, thin tube with a camera through the cut and into your body. This tube is called a laparoscope. The camera sends images from inside your body to a video monitor. This allows the surgeon to see inside your body.
The surgeon may make one or two other small cuts in your belly for inserting special surgical tools into your body. Using these tools, the surgeon can remove samples of tissue to check for signs of disease (a biopsy).
Sometimes during a laparoscopy, the surgeon will use these tools to do procedures to treat certain problems. For example, if a laparoscopy finds a tumor, the surgeon may remove it completely during the same surgery. Many common surgical treatments can be done with laparoscopic surgery.
Laparoscopy is sometimes called "minimally invasive surgery" or "keyhole surgery," because it requires smaller cuts than traditional, "open" surgery. The use of smaller cuts has several benefits, including:
Shorter hospital stays
Less pain
Faster recovery and smaller scars
Laparoscopy is used to help diagnose the cause of symptoms in the belly or pelvis. It's usually done if imaging tests, such as x-rays, ultrasounds, and MRI scans, haven't provided enough information to confirm a diagnosis.
The test is often used to help diagnose:
Digestive diseases
Urinary disorders
Disorders in the female reproductive system, which includes the uterus, ovaries, and fallopian tubes
A surgeon uses laparoscopy to:
Examine organs and glands to look for:
Abnormal growths, such as cysts and tumors (cancerous and not cancerous)
Scar tissue and adhesions
Bleeding
Infections
Collect tissue samples to check for disease
Find out if a known cancer has spread in the body
There are many reasons why you may need a laparoscopy, including if:
You have pain or other symptoms in your belly or pelvis and imaging tests haven't been able to find the cause.
You've been in a serious accident or have been wounded and may have organ injuries.
You have cancer and your health care provider needs to know if it has spread to other parts of your body. This information helps choose your treatment.
You've had abnormal liver tests and your provider doesn't know why.
If you're female, you may need a laparoscopy to:
Find out what's causing problems getting pregnant
Diagnose symptoms that may involve your reproductive organs, including:
Pelvic inflammatory disease (PID)
Endometriosis
Ectopic pregnancy
Uterine fibroids
Ovarian cysts
Laparoscopy is usually done in a hospital or an outpatient clinic. In general, it includes these steps:
You'll wear a hospital gown and lay on an operating table.
Usually, you will have general anesthesia, which is medicine to make you sleep during the surgery. The medicine is injected into your bloodstream through an intravenous (IV) line that's inserted into a vein. You may also inhale a gas from a mask to make you sleep.
To do the laparoscopy, the surgeon will:
Make a small cut near your belly button
Put carbon dioxide gas into your belly to open up space between your organs so it's easier to see them
Insert the laparoscope and small camera into your belly
Move the laparoscope to look at your organs and glands on a computer screen
If you need to have a biopsy or another procedure, the surgeon may need to make more small cuts to insert surgical tools.
When the surgeon is done, the tools and most of the gas will be removed from your body, and the small incisions will be closed and bandaged.
After surgery, you will be moved to a recovery room. In most cases, you'll be able to go home after a few hours, but that depends on what procedures were done during the laparoscopy. Before you leave, you'll get information about what to expect over the next few days at home.
Your provider will let you know how to prepare. Be sure to follow all the instructions. You will need to fast (not eat or drink) for a period of time before a laparoscopy. Ask your provider whether you should take your usual medicines and/or supplements. But don't stop taking any medicine without talking with your provider first.
Plan to wear loose-fitting clothes because after the surgery, your belly may be bloated from the gas and a little sore. You're also likely to feel groggy, so you'll need to plan to have someone take you home.
You may have mild abdominal pain or discomfort for a few days after a laparoscopy. You may also have neck or shoulder pain. That's because the gas used in the surgery may irritate nerves in your belly that run through your shoulder.
After a laparoscopy, serious problems are very uncommon. But they can include bleeding, infection, blood clots, damage to an organ or blood vessel, and problems from the medicine that made you sleep during the procedure.
The results of a laparoscopy depend on the reason for doing the procedure. Your provider can explain what was found and what that information means for your health. In general, your provider will be able to make a very accurate diagnosis of your condition based on the information from a laparoscopy.

Surgeon Performing Laparoscopic Kidney Transplant
This photograph shows the posterior view of two surgeons performing laparoscopic kidney transplant surgery with a view of the patient's abdomen on the monitor. Laparoscopy is a a minimally invasive procedure which requires only small incisions and has replaced conventional operations for kidney removal that used to require a larger opening and therefore longer recovery time. The procedure for living donors involves inserting a special needle into the abdominal cavity to fill it up with gas and create space. A metal tube with a camera, called a laparoscope, is inserted through a two-inch incision in the skin. Surgical instruments can be inserted through the laparoscope, and the surgeon can watch his progress in removing the kidney on a video monitor above the patient. With laparoscopic surgery, donors feel less pain after the transplant, and are able to return to their daily routine sooner.

Laparoscopy (from Ancient Greek λαπάρα (lapara), meaning 'flank, side', and σκοπέω (skopeo), meaning 'to see') is an operation performed in the abdomen or pelvis using small incisions (usually 0.5–1.5 cm) with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.

Gallbladder cancer - Staging
Stages of Gallbladder Cancer
Tests and procedures to stage gallbladder cancer are usually done at the same time as diagnosis.
There are three ways that cancer spreads in the body.
Cancer can spread through tissue, the lymph system, and the blood:
Tissue. The cancer spreads from where it began by growing into nearby areas.
Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.
Cancer may spread from where it began to other parts of the body.
When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.
Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor(metastatic tumor) in another part of the body.
Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.
The metastatic tumor is the same type of cancer as the primary tumor. For example, if gallbladder cancer spreads to the liver, the cancer cells in the liver are actually gallbladder cancer cells. The disease is metastatic gallbladder cancer, not liver cancer.
The following stages are used for gallbladder cancer:
Stage 0 (Carcinoma in Situ)
In stage 0, abnormal cells are found in the mucosa (innermost layer) of the gallbladder wall. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ.
Stage I
In stage I, cancer has formed in the mucosa (innermost layer) of the gallbladder wall and may have spread to the muscle layer of the gallbladder wall.
Stage II
Stage II is divided into stages IIA and IIB, depending on where the cancer has spread in the gallbladder.
In stage IIA, cancer has spread through the muscle layer to the connective tissue layer of the gallbladder wall on the side of the gallbladder that is not near the liver.
In stage IIB, cancer has spread through the muscle layer to the connective tissue layer of the gallbladder wall on the same side as the liver. Cancer has not spread to the liver.
Stage III
Stage III is divided into stages IIIA and IIIB, depending on where the cancer has spread.
In stage IIIA, cancer has spread through the connective tissue layer of the gallbladder wall and one or more of the following is true:
Cancer has spread to the serosa (layer of tissue that covers the gallbladder).
Cancer has spread to the liver.
Cancer has spread to one nearby organ or structure (such as the stomach, small intestine, colon, pancreas, or the bile ducts outside the liver).
In stage IIIB, cancer has formed in the mucosa (innermost layer) of the gallbladder wall and may have spread to the muscle, connective tissue, or serosa (layer of tissue that covers the gallbladder) and may have also spread to the liver or to one nearby organ or structure (such as the stomach, small intestine, colon, pancreas, or the bile ducts outside the liver). Cancer has spread to one to three nearby lymph nodes.
Stage IV
Stage IV is divided into stages IVA and IVB.
In stage IVA, cancer has spread to the portal vein or hepatic artery or to two or more organs or structures other than the liver. Cancer may have spread to one to three nearby lymph nodes.
In stage IVB, cancer may have spread to nearby organs or structures. Cancer has spread:
to four or more nearby lymph nodes; or
to other parts of the body, such as the peritoneum and liver.
For gallbladder cancer, stages are also grouped according to how the cancer may be treated. There are two treatment groups:
Localized (Stage I)
Cancer is found in the wall of the gallbladder and can be completely removed by surgery.
Unresectable, recurrent, or metastatic (Stage II, Stage III, and Stage IV)
Unresectable cancer cannot be removed completely by surgery. Most patients with gallbladder cancer have unresectable cancer.
Recurrent cancer is cancer that has recurred (come back) after it has been treated. Gallbladder cancer may come back in the gallbladder or in other parts of the body.
Metastasis is the spread of cancer from the primary site (place where it started) to other places in the body. Metastaticgallbladder cancer may spread to surrounding tissues, organs, throughout the abdominal cavity, or to distant parts of the body.

Cancer Immunotherapy
Shown here is a pseudo-colored scanning electron micrograph of an oral squamous cancer cell (white) being attacked by two cytotoxic T cells (red), part of a natural immune response. Nanomedicine researchers are creating personalized cancer vaccines by loading neoantigens identified from the patient's tumor into nanoparticles. When presented with immune stimulants, this activates the patient's own immune system, leading to expansion of tumor-specific cytotoxic T cells.

Treatment of Gallbladder Cancer
KEY POINTS
There are different types of treatment for patients with gallbladder cancer.
The following types of treatment are used:
Surgery
Radiation therapy
Chemotherapy
New types of treatment are being tested in clinical trials.
Radiation sensitizers
Targeted therapy
Immunotherapy
Treatment for gallbladder cancer may cause side effects.
Patients may want to think about taking part in a clinical trial.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Follow-up tests may be needed.
There are different types of treatment for patients with gallbladder cancer.
Different types of treatments are available for patients with gallbladder cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Three types of standard treatment are used:
Surgery
Gallbladder cancer may be treated with a cholecystectomy, surgery to remove the gallbladder and some of the tissues around it. Nearby lymph nodes may be removed. A laparoscope is sometimes used to guide gallbladder surgery. The laparoscope is attached to a video camera and inserted through an incision (port) in the abdomen. Surgical instruments are inserted through other ports to perform the surgery. Because there is a risk that gallbladder cancer cells may spread to these ports, tissue surrounding the port sites may also be removed.
If the cancer has spread and cannot be removed, the following types of palliative surgery may relieve symptoms:
Biliary bypass: If the tumor is blocking the bile duct and bile is building up in the gallbladder, a biliary bypass may be done. During this operation, the doctor will cut the gallbladder or bile duct in the area before the blockage and sew it to the small intestine to create a new pathway around the blocked area.
Endoscopic stent placement: If the tumor is blocking the bile duct, surgery may be done to put in a stent (a thin tube) to drain bile that has built up in the area. The doctor may place the stent through a catheter that drains the bile into a bag on the outside of the body or the stent may go around the blocked area and drain the bile into the small intestine.
Percutaneous transhepatic biliary drainage: A procedure done to drain bile when there is a blockage and endoscopic stent placement is not possible. An x-ray of the liver and bile ducts is done to locate the blockage. Images made by ultrasound are used to guide placement of a stent, which is left in the liver to drain bile into the small intestine or a collection bag outside the body. This procedure may be done to relieve jaundice before surgery.
Radiation therapy
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. External radiation therapy uses a machine outside the body to send radiation toward area of the body with cancer.
Chemotherapy
Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy).
New types of treatment are being tested in clinical trials.
This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.
Radiation sensitizers
Clinical trials are studying ways to improve the effect of radiation therapy on tumor cells, including the following:
Hyperthermia therapy: A treatment in which body tissue is exposed to high temperatures to damage and kill cancer cells or to make cancer cells more sensitive to the effects of radiation therapy and certain anticancer drugs.
Radiosensitizers: Drugs that make tumor cells more sensitive to radiation therapy. Giving radiation therapy together with radiosensitizers may kill more tumor cells.
Targeted therapy
Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells. Targeted therapies usually cause less harm to normal cells than chemotherapy or radiation therapy do. The following targeted therapies are being studied in patients with gallbladder cancer that is locally advanced and cannot be removed by surgery or has spread to other parts of the body:
Ivosidenib is a type of targeted therapy that blocks a specific mutation in a gene called IDH1. It works by slowing or stopping the growth of cancer cells.
Pemigatinib is a type of targeted therapy that blocks specific changes in a gene called FGFR2. This may help keep cancer cells from growing and may kill them.
Immunotherapy
Immunotherapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer. This cancer treatment is a type of biologic therapy.
Immune checkpoint inhibitor therapy is a type of immunotherapy that may be used to treat gallbladder cancer.
PD-1 and PD-L1 inhibitor therapy: PD-1 is a protein on the surface of T cells that helps keep the body’s immune responses in check. PD-L1 is a protein found on some types of cancer cells. When PD-1 attaches to PD-L1, it stops the T cell from killing the cancer cell. PD-1 and PD-L1 inhibitors keep PD-1 and PD-L1 proteins from attaching to each other. This allows the T cells to kill cancer cells. Pembrolizumab is a type of PD-1 inhibitor that may be used in patients whose cancer is locally advanced and cannot be removed by surgery or has spread to other parts of the body.
Immune checkpoint inhibitor. Checkpoint proteins, such as PD-L1 on tumor cells and PD-1 on T cells, help keep immune responses in check. The binding of PD-L1 to PD-1 keeps T cells from killing tumor cells in the body (left panel). Blocking the binding of PD-L1 to PD-1 with an immune checkpoint inhibitor (anti-PD-L1 or anti-PD-1) allows the T cells to kill tumor cells (right panel).
Treatment for gallbladder cancer may cause side effects.
Patients may want to think about taking part in a clinical trial.
For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.
Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.
Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
Patients can enter clinical trials before, during, or after starting their cancer treatment.
Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.
Follow-up tests may be needed.
Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.
Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.
Treatment of Localized and Locally Advanced Gallbladder Cancer
Treatment of localized and locally advanced gallbladder cancer may include the following:
Surgery to remove the gallbladder and some of the tissue around it. Part of the liver and nearby lymph nodes may also be removed. Radiation therapy with or without chemotherapy may follow surgery.
Radiation therapy with or without chemotherapy.
A clinical trial of radiation therapy with radiosensitizers.
Treatment of Unresectable, Metastatic, or Recurrent Gallbladder Cancer
Treatment of unresectable, metastatic, or recurrent gallbladder cancer is usually within a clinical trial. Treatment may include the following:
Percutaneous transhepatic biliary drainage or the placement of stents to relieve symptoms caused by blocked bile ducts. This may be followed by radiation therapy as palliative treatment.
Surgery as palliative treatment to relieve symptoms caused by blocked bile ducts.
Chemotherapy.
A clinical trial of new ways to give palliative radiation therapy, such as giving it together with hyperthermia therapy, radiosensitizers, or chemotherapy.
A clinical trial of targeted therapy or immunotherapy for patients with mutations (changes) in certain genes.

Finding New Ways to Help the Immune System Fight Cancer
Researchers are tapping into the innate immune system by harnessing dendritic cells to activate T-cell immunity, helping macrophages engulf cancer cells, and engineering natural killer cells to target cancer. Researchers are also investigating the gut microbiome’s role in immunity and targeting the microbiome for cancer therapy.

Dendritic cell-based immunotherapy
In dendritic cell therapy blood cells are removed from the body. The blood mononuclear cells are incubated with a tumour antigen or tumour cell lysates that contain many tumour antigens. The cells are also activated by use of immuno-stimulatory molecules. This process produces mature antigen-loaded dendritic cells that are returned to the original donor. The dendritic cells induce immune response to the tumour.

Prognosis of Gallbladder Cancer
The prognosis (chance of recovery) and treatment options depend on the following:
The stage of the cancer (whether the cancer has spread from the gallbladder to other places in the body).
Whether the cancer can be completely removed by surgery.
The type of gallbladder cancer (how the cancer cell looks under a microscope).
Whether the cancer has just been diagnosed or has recurred (come back).
Treatment may also depend on the age and general health of the patient and whether the cancer is causing signs or symptoms.
Gallbladder cancer can be cured only if it is found before it has spread, when it can be removed by surgery. If the cancer has spread, palliative treatment can improve the patient's quality of life by controlling the symptoms and complications of this disease.

Gallbladder Cancer
Gallbladder cancer is a disease in which malignant (cancerous) cells form in the tissues of the gallbladder. Cancer of the gallbladder is rare. It's also difficult to diagnose because there are no symptoms in its early stages. Read about symptoms, diagnosis, treatment options, and prognosis.
