Description

The Gamma-Glutamyl Transferase (GGT) test is used to determine if you have a possible liver or bile duct disease or to differentiate between liver and bone disease as a cause of elevated alkaline phosphatase (ALP). It can also be used to screen for or monitor alcohol abuse. It measures GGT, an enzyme found mostly in the liver. Elevated levels of GGT can indicate you have a disease that could cause damage to your liver or bile ducts.

Overview

GGT is an enzyme found mainly in the liver. This test measures the level of GGT in the blood to help detect liver and bile duct disorders. It is often done alongside other liver function tests.

Risk assessment

Risk Assessment / Indications:

  • Suspected liver disease (e.g. hepatitis, cirrhosis)

  • Alcohol abuse monitoring

  • Bile duct obstruction

  • Evaluating unexplained elevated alkaline phosphatase (ALP)

  • Screening for chronic alcohol consumption

  • Medication-related liver injury

 

Ranges

Normal Range:

  • Men: 7 – 50 U/L

  • Women: 5 – 40 U/L
    (May vary slightly by lab)

Test result interpretation

Interpretation:

  • High GGT:

    • Liver damage

    • Bile duct problems

    • Chronic alcohol use

    • Pancreatic or heart disease

    • Certain drugs (e.g., phenytoin, barbiturates)

  • Normal/Low GGT:

    • Usually indicates no liver damage

    • Low GGT alone is typically not a concern

Note: GGT levels must be interpreted in conjunction with other liver enzymes (ALT, AST, ALP).
