What do the results mean?
If your results show higher than normal levels of GGT, it may be a sign of liver damage. The damage may be due to one of the following conditions:
Hepatitis
Cirrhosis
Alcohol use disorder
Pancreatitis
Diabetes
Congestive heart failure
Side effect of a drug. Certain medicines can cause liver damage in some people.
The results can't show which condition you have, but it can help show how much liver damage you have. Usually, the higher the level of GGT, the greater the level of damage to the liver.
If your results show you have low or normal levels of GGT, it means you probably don't have liver disease.
Your results may also be compared with the results of an ALP test. ALP tests help diagnose bone disorders. Together your results may show one of the following:
High levels of ALP and high levels of GGT means your symptoms are likely due to liver disorder and not a bone disorder.
High levels of ALP and low or normal GGT means it's more likely you have a bone disorder.
If you have questions about your results, talk to your health care provider.
