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. Reference: (1) Goldberg DM, Martin JV (1975).
The GGT test is sometimes used to help detect liver disease and bile duct obstructions. It is usually ordered in conjunction with or as follow up to other liver tests such as ALT, AST, ALP, and bilirubin. low or normal GGT test result indicates that it is unlikely that a person has liver disease or has consumed any alcohol. A high GGT level can help rule out bone disease as the cause of an increased ALP level, but if GGT is low or normal, then an increased ALP is more likely due to bone disease. ^ Back to top.
