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 one of the liver enzymes that are usually restricted to the areas of the liver and some other organs but when there is some kind of liver disease, the levels of this enzyme increase because the enzyme starts to leak out of the liver into the bloodstream.levated GGT levels themselves do not mean anything as the levels of GGT tend to fluctuate during the day; however, the presence of jaundice is usually confirmation enough of some kind of liver damage. A GGT test should then be compared with an ALP test.
