Aspartate Amino Transferase

Alias: AST

Discipline: Clinical Chemistry

Test information: Aspartate aminotransferase (AST) is widely distributed, principally in liver, heart, skeletal muscle, kidney and red blood cells. Increased concentrations are found in diseases involving these tissues. Specifically hepatobiliary diseases including cirrhosis, metastatic cancer and viral hepatitis increase serum AST levels. Following myocardial infarction, AST is elevated and reaches a peak 2 days after onset.
