Description
The gamma-glutamyl transpeptidase (GGT) test measures the amount of the enzyme GGT in your blood. Enzymes are molecules that are necessary for chemical reactions in your body. GGT functions in the body as a transport molecule, helping to move other molecules around the body. It plays a significant role in helping the liver metabolise drugs and other toxins.
Precaution
Our doctor may instruct you to fast for eight hours before the test and to stop taking certain medications.
