The Gamma-Glutamyl Transferase (GGT) blood test is a test that measures the levels of GGT in the blood. GGT is an enzyme found in many tissues in the body, with the highest levels found in the liver. Elevated levels of GGT in the blood may indicate liver damage or disease, such as hepatitis, cirrhosis, or liver cancer.
The GGT blood test is often used in conjunction with other liver function tests to help diagnose and monitor liver diseases. It may also be used to monitor alcohol consumption, as heavy drinking can cause an increase in GGT levels.
To prepare for the GGT blood test, it is usually recommended to fast for 8-12 hours before the test, as certain foods and medications can affect the results. It is important to follow any instructions given by the test provider before the test.
If your GGT levels are found to be elevated, further testing may be needed to determine the underlying cause and appropriate treatment.
