Your Liver and the GGT Test: What the Numbers Mean

The Gamma-Glutamyl Transferase (GGT) enzyme is an important indicator of liver health. The ggt blood test measures the amount of this enzyme in your blood, helping detect liver damage, bile duct issues, or alcohol-related liver disease. It’s often used with other liver function tests to provide a clearer diagnosis. Symptoms like fatigue, jaundice, or abdominal discomfort may prompt this test. No special preparation is needed, though avoiding alcohol beforehand is recommended. Early detection through this test can support timely medical care.
