What Is Gamma GT? Gamma-glutamyltransferase or Gamma GT (GGT) is an enzyme found predominantly in the liver. The blood level of GGT increases if the liver becomes injured or if the bile ducts become obstructed affecting the flow of bile. Therefore, GGT is a good biomarker for detecting liver disease and bile duct injury.
Why take a Gamma GT blood test?
Gamma-glutamyltransferase is a good biomarker for detecting liver disease, especially alcohol-related liver disease. You may require a GGT test if you are displaying symptoms of liver injury. It can also help to identify why the concentration of alkaline phosphatase (ALP) may be increased. For example, if both ALP and GGT are raised then this is indicative of some liver disease or disease of the bile duct. Whereas a raised ALP level alone usually indicates bone disease.
