This test is used to evaluate the functioning of liver, bile duct and pancreas. It is widely used for the diagnosis of any kind of liver damage. Screening of this enzyme, along with some other (Aspartate aminotransferase (AST) and alanine aminotransferase (ALT), provides information about the status of liver function. The GGT test is recommended to determine the underlying causes of increase in ALP (alkaline phosphatase levels), which is also elevated in different bone diseases. Low levels of GGT and high level of ALP are determinants of bone diseases, whereas high levels of AST, ALT, ALP and GT are increased in hepatitis and have been used as markers of acute hepatitis. GGT is found to be elevated in 75% of alcohol abusers and thus is used for the screening of such individuals.
