GGT serum measurement provides a very sensitive indicator of the presence or absence of hepatobiliary disease. However the usefulness of measurement of serum GGT is limited by its lack of specificity. Drugs such as phenytoin and barbiturates may cause high GGT levels (2). The reported sensitivity of a raised GGT for detecting alcohol ingestion has ranged from 52% to 94% (3,4). The linked page GGT in hepatobiliary disease details hepatobiliary causes of a raised GGT.

Gamma-Glutamyl Transpeptidase (GGT) Test. The gamma-glutamyl transpeptidase (GGT) test measures the amount of the enzyme GGT in your blood. Enzymes are molecules that are necessary for chemical reactions in your body.enerally, the higher the GGT level the greater the damage to the liver. Some of the conditions that result in increased GGT include: 1  overuse of alcohol. 2  chronic viral hepatitis. 3  lack of blood flow to the liver. 4  liver tumor. 5  cirrhosis, or scarred liver. 6  overuse of certain drugs or other toxins.
