What This Value Measures

Gamma-GT is an enzyme found in the liver and bile ducts. It reacts sensitively to stress on the liver and the biliary tract.

Elevated Value

An elevated level may indicate alcohol consumption, fatty liver, medications, or impaired bile flow.

Low Value

Low levels generally have no clinical significance.

Reference ranges are typical guide values for adults and vary depending on the laboratory, measurement method, age and sex — always compare with the range stated on your own report. A value outside the range does not automatically mean an illness, and a value within the range does not rule one out. The trend and overall picture are usually more informative than a single value. The doctor's assessment is always decisive.
