GGT Test (Gamma Glutamyl Transferase)

This blood test is used to measure levels of Gamma Glutamyl Transferase (GGT) to help evaluate for liver disease or damage.

Increased levels of GGT can indicate diseases of the liver, kidneys, gallbladder, bile ducts and/or pancreas.

Elevated GGT is found in all forms of liver disease. Measurement of GGT is used in the diagnosis and treatment of alcoholic cirrhosis, as well as primary and secondary liver tumors. It is more sensitive than alkaline phosphatase, the transaminases, and leucine aminopeptidase in detecting obstructive jaundice, cholangitis, and cholecystitis.
