What is the GGT Test?
The GGT test measures gamma-glutamyl transferase, an enzyme found mainly in the liver and bile ducts. It rises when bile flow is blocked and with alcohol use. It is often used to tell whether a raised alkaline phosphatase comes from the liver or from bone.
GGT Test normal range
| Measurement | Typical adult value |
|---|---|
| Men | About 8–61 U/L |
| Women | About 5–36 U/L |
Ranges vary by lab and method. GGT is naturally higher in men and rises with age and body weight.
Ranges differ between laboratories and methods. The reference range printed on your own report is the one to read your result against.
What your GGT Test result means
- High
- Common causes are alcohol, fatty liver, bile duct blockage and some medicines such as phenytoin or carbamazepine. A high GGT with a high ALP points to the liver or bile ducts rather than bone.
- Normal with high ALP
- Suggests the raised ALP is more likely from bone than from the liver.
One result is not a diagnosis. A doctor reads it with your symptoms, history, medicines and other tests.
Why is the GGT Test done?
- A high alkaline phosphatase, to check whether the liver is the source
- Suspected bile duct blockage
- Assessing regular alcohol use
- As part of an extended liver function test
