Gamma-Glutamyl Transpeptidase AST is an enzyme found in high levels in the liver, heart, and muscles. It is also found in lesser amounts in other tissues. An enzyme is a protein that causes a specific chemical change in the body. This test is mainly done along with other tests (such as ALT, ALP, and bilirubin) to diagnose and monitor liver disease.

AST/ALT ratio The AST/ALT ratio is the ratio between the concentrations of the enzymes aspartate transaminase (AST) and alanine transaminase (ALT) in the blood of a human or animal. It is measured with a blood test and is sometimes useful in medical diagnosis to differentiate between causes of liver damage, or hepatotoxicity.

AST Levels Normal serum AST is 14-20 IU per liter in men and 10-36 IU per liter in women. When a blood test for AST indicates elevation above normal range, the indication is that damage may be present to one of the organs where AST is normally found.

AST (SGOT) Hepatitis C. AST, or aspartate aminotransferase, is 1 of the 2 liver enzymes.. It is also known as serum glutamic-oxaloacetic transaminase, or SGOT. AST is a protein made by liver cells. When liver cells are damaged, AST leaks out into the bloodstream and the level of AST in the blood becomes higher than normal.

Aspartate transaminase Aspartate transaminase (AST) or aspartate aminotransferase, also known as AspAT/ASAT/AAT or serum glutamic oxaloacetic transaminase (SGOT), is a pyridoxal phosphate (PLP)-dependent transaminase enzyme (EC 2.6.1.1) that was first described by Arthur Karmen and colleagues in 1954.

Aspartate Aminotransferase (AST)  [en EspaÃ±ol] Aspartate Aminotransferase (AST) An aspartate aminotransferase (AST) test measures the amount of this enzyme in the blood. AST is normally found in red blood cells, liver, heart, muscle tissue, pancreas, and kidneys. AST formerly was called serum glutamic oxaloacetic transaminase (SGOT). Low levels of AST are normally found in the blood. When body tissue or an organ such as the heart or liver is diseased or damaged, additional AST is released into the bloodstream. The amount of AST in the blood is directly related to the extent of the tissue damage.

- Liver Enzyme Tests. Alanine Transaminase (ALT) is an enzyme mainly found in your liver. The ALT test measures the level of ALT in your blood. Consistently high levels of ALT in your blood can be a sign of liver damage. Aspartate Transaminase (AST) is an enzyme found in large amounts in your liver and other parts of your body. The AST test measures the level of AST in your blood.

- Aspartate transaminase (AST) is an enzyme produced in the liver. It plays an important role in amino acid metabolism. It is normally found in the liver, heart, muscles, brain, kidneys, and red blood cells. The level of AST in the blood is often tested to reveal the presence of liver disease or of damage to the liver.hen elevated AST indicates damage to the liver, this damage can come from a variety of different causes, both in the sense of indicating various liver diseases and also in the sense of the diseases being due to various causes.

- The alanine aminotransferase (ALT) test is typically used to detect liver injury. It is often ordered in conjunction with aspartate aminotransferase (AST) as part of a liver panel or comprehensive metabolic panel (CMP) to screen for and/or help diagnose liver disease. ALT is an enzyme found mostly in the cells of the liver and kidney. When the liver is damaged, ALT is released into the blood. This makes ALT a useful test for early detection of liver damage. AST and ALT are considered to be two of the most important tests to detect liver injury, although ALT is more specific to the liver than is AST.

What does AST in a lipid panel mean? AST or aspartate aminotransferase is a test of liver function. In roughly 1 to 2% of patients starting statin therapy, AST and ALT (alanine aminotransferase, another test that monitors liver function) may increase. However, significant increases in AST or ALT are extremely rare and new guidelines no longer recommend routine monitoring of liver function studies with statin therapy.

Aspartate transaminase AST catalyzes the reversible transfer of an α-amino group between aspartate and glutamate and, as such, is an important enzyme in amino acid metabolism. AST is found in the liver, heart, skeletal muscle, kidneys, brain, and red blood cells. Serum AST level, serum ALT (alanine transaminase) level, and their ratio (AST/ALT ratio) are commonly measured clinically as biomarkers for liver health. The tests are part of blood panels.

Liver Blood Tests (Normal, Low, and High Ranges & Results) AST (SGOT) and ALT (SGPT) are reasonably sensitive indicators of liver damage or injury from different types of diseases or conditions. However, it must be emphasized that higher-than-normal levels of these liver enzymes should not be automatically equated with liver disease. They may mean liver problems or they may not. For example, elevations of these enzymes can occur with muscle damage.

How Sgot Is Determinant Of Health Of Liver, Heart And Human Body Muscles? The SGOT (serum glutamic-oxaloacetic transminase) or AST test, actually, measures the amount of a protein enzyme called glutamic-oxaloacetic transaminase occurring in human blood of the patient. This enzyme is normally found in the liver, heart muscles, muscles, bones and red blood cells.

- Guide. An alanine aminotransferase (ALT) test measures the amount of this enzyme in the blood. ALT is found mainly in the liver, but also in smaller amounts in the kidneys, heart, muscles, and pancreas.ALT was formerly called serum glutamic pyruvic transaminase (SGPT).he ALT test is often done along with other tests that check for liver damage, including aspartate aminotransferase (AST), alkaline phosphatase, lactate dehydrogenase (LDH), and bilirubin. Both ALT and AST levels are reliable tests for liver damage.
