CLINICAL SIGNIFICANCE
Gamma-glutamyl transferase (γ-GT) is a cellular enzyme with wide
tissue distribution in the body, primarily in the kidney, pancreas, liver
and prostate.
Measurements of gamma-glutamyl transferase (γ-GT) activity are used
in the diagnosis and treatment of hepatobiliary diseases such biliary
obstruction, cirrhosis or liver tumours1,2,5,6.
Clinical diagnosis should not be made on a single test result; it should
integrate clinical and other laboratory data.
