What does Serum Gamma GT level mean?

Serum Gamma GT (GGT) level is a blood test that measures the amount of the enzyme gamma-glutamyl transferase in the bloodstream. Elevated GGT levels can indicate liver disease, bile duct obstructions, or excessive alcohol consumption, as the enzyme is primarily found in the liver and bile ducts. It is often used in conjunction with other liver function tests to assess liver health and diagnose potential disorders. However, elevated GGT can also be influenced by factors such as certain medications and other medical conditions.
