Ask a question


The gamma-glutamyltransferase (gamma-GT), also known as gamma-glutamyl transpeptidase are proteins, specifically enzymes naturally produced by the body, mainly in the liver. The levels of gamma-GT in the blood are normally less than 60 international units per liter, but some causes may be responsible for an increase in this amount. The most common cause is chronic alcoholism. Gamma-GT may also be increased in other diseases such as hepatitis and any liver damage in general, diabetes, medications, and certain infections.
