SGPT medical definition

Serum pyruvate aminotransferase; an enzyme in serum and body tissues that catalyzes the transfer of amino acid groups from L-alanine to 2-ketoglutarate or the reverse, thus allowing nitrogen to be excreted or incorporated into other compounds, used to measure liver function. Also called alanine aminotransferase, ALT, glutamic-pyruvic transaminase, GPT.
