Serum glutamic oxaloacetic transaminase (SGOT): An enzyme that is normally present in liver and heart cells. SGOT is released into blood when the liver or heart is damaged. The blood SGOT levels are thus elevated with liver damage (for example, from viral hepatitis) or with an insult to the heart (for example, from a heart attack). Some medications can also raise SGOT levels. SGOT is also called aspartate aminotransferase (AST).
