A glutamic-oxaloacetic transaminase (SGOT) or aspartate aminotransferase (AST) test measures the levels of the enzyme AST in the blood to assess liver health. Numbers over 50 for cisgender males and 45 for cisgender females indicate potential liver damage. The SGOT test is a blood test that’s part of a liver profile. It measures one of two This enzyme is now usually called AST, which stands for A SGOT test may be used to help your doctor diagnose liver damage or The test may be used to evaluate liver health for people who are already known to have conditions that affect their liver, such as hepatitis C. SGOT is found in several areas of your body, including your kidneys, muscles, heart, and brain. If any of these areas are damaged, your SGOT levels may be higher than normal. For example, the levels could be raised during a heart attack or if you’ve had a muscle injury. Because SGOT appears throughout your body, part of the liver profile also includes an The SGOT test is a simple blood test. It can technically be done without any special preparation. Still, there are a couple steps you can take to make the process easier. Avoid taking any over-the-counter (OTC) medications, including acetaminophen (Tylenol), in the two days before your test.

Overview A bilirubin test measures the levels of bilirubin in your blood. Bilirubin (bil-ih-ROO-bin) is a yellowish pigment that is made during the breakdown of red blood cells. Bilirubin passes through the liver and is eventually excreted out of the body. Higher than usual levels of bilirubin may indicate different types of liver or bile duct problems. Sometimes, higher bilirubin levels may be caused by an increased rate of destruction of red blood cells. Why it's done Bilirubin testing is usually one of a group of tests to check the health of your liver. Bilirubin testing may be done to: • Investigate jaundice — a yellowing of the skin and eyes caused by high levels of bilirubin. This test is commonly used to measure bilirubin levels in newborns with infant jaundice. • Determine whether there might be blockage in your bile ducts, in either the liver or the gallbladder. • Help detect liver disease, particularly hepatitis, or monitor its progression. • Help evaluate anemia caused by the destruction of red blood cells. • Help follow how a treatment is working. • Help evaluate a suspected drug toxicity. Some common tests that might be done at the same time as bilirubin testing include: • Liver function tests. Blood tests that measure certain enzymes or proteins in your blood. • Albumin and total protein. Levels of albumin — a protein made by the liver — and total protein show how well your liver is making certain proteins. These proteins are necessary for your body to fight ...
