Human GPT/ALT is an enzyme that catalyzes the reversible transfer of an amino group from alanine to a-ketoglutarate. Human alanine aminotransferase (ALT) is found in serum and in various bodily tissues but is most commonly associated with the liver. Also called serum glutamate pyruvate transaminase (SGPT) or alanine aminotransferase.

Elevated levels of Alanine transaminase (ALT) often suggest the existence of other medical problems such as alcoholism, viral hepatitis, congestive heart failure, liver damage, biliary duct problems, infectious mononucleosis, or myopathy.
