Higher than normal levels of bilirubin may indicate different types of liver or bile duct problems. SGOT:-SGOT:- The SGOT test is a blood test that's part of a liver profile. It measures one of two liver enzymes, called serum glutamic-oxaloacetic transaminase. This enzyme is now usually called AST, which stands for aspartate aminotransferase. An SGOT test (or AST test) evaluates how much of the liver enzyme is in the blood.
