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.

GGT is concentrated in the liver, but itâs also present in the gallbladder, spleen, pancreas, and kidneys. GGT blood levels are usually high when the liver is damaged. This test is often done with other tests that measure liver enzymes if thereâs a possibility of liver damage.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.
