AST blood test
An Aspartate Aminotransferase (AST) blood test measures the amount of AST enzyme in the blood. AST or Serum Glutamic Oxaloacetic Transminase (SGOT) is found in high concentrations in heart muscle, liver cells, skeletal muscle cells, pancreas and kidneys, in red blood cells and to a lesser degree in other tissues. Usually an AST blood test is done at the same time as ALT blood test. The ratio of AST blood levels to ALT blood levels helps to determine whether any organ particularly the liver has been damaged. AST blood test is primarily used to diagnose and monitor diseases of the liver such as hepatitis and cirrhosis. AST blood test helps to monitor recovery from or treatement for liver disease. Normal range for a AST blood test is 8 - 35 units per liter (U/L) or 5 - 40 international units per liter (IU/L). AST levels in the blood rise when there is tissue damage. Very high levels of AST in the blood indicate possible tumor, pancreatitis, cancer, cirrhosis, muscular dystrophy or heart failure.
