The Gamma-Glutamyl Transferase (GGT) Test at Pamel Laboratories measures the level of the GGT enzyme in your blood. GGT is primarily found in the liver, and elevated levels may indicate liver damage, bile duct problems, or excessive alcohol use. This test is often used alongside other liver function tests to give a clearer picture of liver health.
GGT is particularly sensitive to bile flow obstruction and can help detect liver disease at an early stage, even when other tests appear normal.
What the Test Measures:
Purpose of the Test:
-
Diagnose and monitor:
-
Liver disease (hepatitis, cirrhosis)
-
Bile duct obstruction
-
Alcohol-related liver damage
-
Fatty liver or liver tumors
-
Used to:
-
Determine cause of elevated alkaline phosphatase (ALP)
-
Evaluate liver health in people on medications affecting the liver
-
Assess alcohol consumption levels in chronic alcohol users
Sample Type: Blood sample (serum)
Fasting Required: Yes (8–12 hours is preferred)
Turnaround Time: Same day or within 24 hours

-
Elevated GGT: Suggests liver or bile duct dysfunction, heavy alcohol use, or drug-induced liver damage
-
Normal or low GGT: Generally indicates no active liver or bile disease
