Aspartate aminotransferase or Serum glutamic-oxaloacetic transaminase (SGOT).

An AST test is done to measure the amounts of the AST ensyme in your blood.  Elevated AST ensymes, while not specific for liver disease,  can aid in the diagnosing and monitoring of the course of liver disease. 

Your provider will test your AST level, for instance, if you are taking a long-term medication that can affect your liver cells.

The normal range for AST is 10 - 34 IU/L.
