About test
What does Gamma Glutamyl Transferase (GGT) measure?
The Gamma Glutamyl Transferase (GGT) test measures the level of GGT, an enzyme found mainly in the liver and bile ducts. It may be used to help evaluate liver or bile duct irritation, possible blockage of bile flow, or alcohol-related liver effects. Healthcare professionals may also order it alongside other liver tests to help interpret abnormal liver enzyme results and monitor known liver or biliary conditions.
