The SGOT (Serum Glutamic-Oxaloacetic Transaminase) test, now called the AST (Aspartate Aminotransferase) test, measures levels of the AST enzyme in your blood, primarily to check liver health but also heart, muscle, and kidney function, as elevated levels signal cell damage in these organs. It’s a key part of a liver panel, often done with SGPT, detecting issues like hepatitis, alcohol damage, or medication side effects, indicated by symptoms like fatigue, jaundice, or abdominal pain
