GAMMA GLUTAMYL TRANSFERASE (GGT)

What is Gamma Glutamyl Transferase?

A Gamma Glutamyl Transferase test measures the amount of GGT, a liver enzyme, in the body. This test is used to check for any blockage in the bile ducts and monitor the treatment response of liver diseases such as jaundice and hepatitis.

What does Gamma Glutamyl Transferase measure?

Gamma-Glutamyl Transferase (GGT) is an enzyme found in various organs, with the highest concentration in the liver. Usually, this enzyme is present in low levels in the blood. However, when there is liver damage or disease, GGT is released into the bloodstream, causing an increase in GGT levels. In addition to the liver, GGT can also be elevated in conditions affecting the bile ducts or the pancreas. It is usually, the first liver enzyme to rise in the blood when there is any damage or obstruction in the bile duct, making it one of the most sensitive liver enzyme tests for detecting bile duct problems.
