Gamma Glutamyl Transferase

GGT is an enzyme that speeds up various chemical reactions in the body. It is abundantly found in the liver and in smaller quantities in many other body organs. The primary role of GGT is to transport molecules around the body. It also helps the liver metabolize medicines and other harmful substances (toxins) and aids in their elimination.

The GGT test is commonly used to detect liver diseases such as hepatitis, cirrhosis, or fatty liver disease. Your doctor may suggest this test when you show symptoms such as loss of appetite, belly pain and swelling, dark-colored urine, bruises, vomiting, and yellowing of the skin and eyes. It can also help identify alcohol-related liver problems, as GGT levels tend to rise with alcohol consumption. Usually, no special preparation is required for a GGT test. You may eat and drink as per your daily routine.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. Narrate your complete medical history to help the doctor correlate your clinical and laboratory findings. The test results will help them get insights into liver health, identify potential liver or bile duct issues, and formulate an overall treatment plan.
