ALT

Aliases: Alanine Transaminase, ALT, SGPT, Glutamic-Pyruvic Transaminase, GPT

Group: Liver function

Description:

Alanine transaminase is an enzyme found mainly in the liver. When liver cells are damaged, they release ALT into the blood. Elevated ALT levels in the blood can be a sign of liver injury or disease. Some types of liver disease cause elevated ALT levels before they cause symptoms. Therefore, an ALT blood test can help diagnose some liver diseases early.
