What this test is
The test measures GGT in blood. The enzyme is concentrated in the liver and bile ducts, so higher values indicate impaired bile flow or effects from alcohol and drugs.
Category: Clinical Chemistry
Gamma glutamyl transpeptidase (GGT)
GGT is an enzyme sensitive to liver and bile duct problems, often raised by alcohol, liver-affecting medicines and cholestasis. It helps clarify the cause of a high ALP.
What it is used for, and who should test
- Distinguishing whether a raised ALP comes from liver or bile ducts, where GGT usually rises too
- Monitoring regular drinkers and people on long-term medicines
- Assessing cholestasis in certain chronic liver diseases
Sample and preparation
- Sample
- 2-3 mL of blood in a serum tube
- Preparation
- Fast for 8-10 hours and avoid alcohol for 24-48 hours, as GGT is particularly alcohol-sensitive.
