Liver and Muscle Health Check - Aspartate Aminotransferase (AST) Test

Aspartate aminotransferase (AST), formerly known as GOT, is an intracellular enzyme involved in amino acid metabolism. It is found in high concentrations in liver cells, heart (myocardium), skeletal muscle, kidneys, and brain. Its serum level rises when cell membranes in any of these tissues are damaged, making it less specific for the liver than ALT.
