Gamma-glutamyl transferase (GGT) is an abundant enzyme found in many tissues throughout the body, but with the highest amounts in the liver. It is made in the liver and is one of the 4 liver enzymes that is tested in order to evaluate liver and bile duct function. This enzyme is typically the first one to rise when there is obstruction in the bile ducts, and is very sensitive for diagnosing this. It can also be used to evaluate liver function and aid in the detection of liver disease like hepatitis and liver cancer, but GGT is not the most specific enzyme for this. This test measures the amount of GGT in the blood.
This test is performed in following conditions such as:
