Gamma Glutamyl Transferase (GGT)
Measures a liver enzyme in the blood to check liver and bile duct health and alcohol-related damage.
What is a Gamma Glutamyl Transferase (GGT) Test?
Gamma Glutamyl Transferase (GGT) measures the level of the GGT enzyme in your blood. This enzyme helps move antioxidants and other molecules in and out of liver cells and bile ducts. GGT is an important marker of liver and bile duct health. High levels may signal liver injury, bile duct blockage, alcohol-related liver damage, or certain drug effects. Doctors use GGT alongside other liver tests to find the cause of abnormal results. It helps tell whether a raised alkaline phosphatase comes from the liver. Clinicians also use it to monitor treatment, check ongoing liver damage, and support evaluations for alcohol use or suspected liver disease.
Gamma Glutamyl Transferase (GGT) Test Preparation
Do not eat or drink anything except water for 8-12 hours before the test
Gamma Glutamyl Transferase (GGT) Test Parameters
The Gamma Glutamyl Transferase (GGT) test evaluates various parameters related to the different components. Here are the main parameters that are checked in the test:
Why Take a Gamma Glutamyl Transferase (GGT) Test?
GGT is often ordered as part of a liver function panel when doctors suspect liver or bile duct problems. It is requested for symptoms like jaundice, abdominal pain, dark urine, or unexplained fatigue and when other liver tests are abnormal. Abnormal results can come from alcohol use, fatty liver, hepatitis, bile duct obstruction, or certain medicines. Family history of liver disease may prompt earlier or repeated testing.
