AST Aspartate aminotransferase

AST Aspartate aminotransferase; Serum glutamic-oxaloacetic transaminase; SGOT
 is an enzyme found in high amounts in heart muscle and liver and skeletal muscle cells. It is also found in lesser amounts in other tissues.

The normal range is 10 to 34 IU/L.

Note: IU/L = international units per lite
What Abnormal Results Mean

Diseases that affect liver cells increase the levels of AST. However, increased levels of AST alone do not specifically indicate liver disease.Heart attack
Hereditary hemochromatosis
Infectious mononucleosis
Lack of blood flow to the liver (liver ischemia)
Liver necrosis
Liver tumor
An increase in AST levels may indicate:
Acute hemolytic anemia
Acute pancreatitis
Acute renal failure
Multiple trauma
Primary muscle disease
Progressive muscular dystrophy
Severe deep burn
Skeletal muscle trauma
Use of drugs that are poisonous to the liver

Recent cardiac catheterization or angioplasty
Recent convulsion
Recent surgery.
