Gamma-glutamyl transferase (GGT) test measures the levels of enzyme GGT in the blood. It is very useful in diagnosing hepatobiliary disease.
If you have symptoms of hepatobiliary disease presented as hepatomegaly, hypoalbuminemia and ascites, jaundice or icterus and so on, you may need this test.
Reference values of GGT for adults are as follows:
- Normal values of GGT for adult males range between 8-61 U/L.
- Normal values of GGT for adult females range between 5-36 U/L.
Increased levels of GGT are related with hepatobiliary disease.
Normal levels of GGT are related with skeletal disease.
