Decoding the Gamma GT Blood Test: Purpose, Procedure, and Results

The Gamma-Glutamyl Transferase (GGT) test is a blood test that measures the level of the GGT enzyme in your bloodstream. The gamma gt blood test helps detect liver damage, bile duct issues, or alcohol-related liver disease. Elevated GGT levels can indicate liver damage, bile duct issues, or alcohol-related liver disease. Healthcare providers often use this test alongside other liver function tests to diagnose or monitor liver conditions. Symptoms prompting a GGT test include jaundice, fatigue, and abdominal pain. No special preparation is typically required, though avoiding alcohol before the test is advisable.
