Gamma-Glutamyltransferase - GGT

Gamma-glutamyltransferase (GGT) is an enzyme present in the liver, bile ducts, and kidney cells. Elevated levels often indicate liver disease, bile duct obstruction, alcohol use, or oxidative stress.

This test helps assess hepatic function and biliary health, often interpreted alongside other liver enzymes (ALT, AST, ALP) to provide a clearer picture of liver and cholestatic conditions.
