A GGT (gamma-glutamyl transferase) is a test to look for GGT in your blood. GGT is a protein (enzyme) that speeds up chemical reactions in the body. It is found mainly in the liver and the bile ducts.
Gamma-glutamyl transferase is also called gamma-glutamyl transpeptidase.
The test is done to check for alcohol problems, liver disease, and bile duct blockage. It is usually done along with other tests, such as alanine aminotransferase, or ALT.
In general, you don’t need to prepare before having this test. Your doctor may give you some specific instructions.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and
call your doctor or nurse call line if you are having problems. It's also a good idea to keep a
list of the medicines you take. Ask your doctor when you can expect to have
your test results.
