Gamma-GT (alcohol) - Definition

Ask a question


The gamma-GT (gamma-glutamyltransferase or transpeptidase) enzymes are produced mainly by the liver; one of its characteristics is to multiply when the body is regularly exposed to alcohol. In chronic alcoholism, the levels of these proteins in the blood are increased. These levels, detected through a blood test, are not specific to alcoholism and can also be increased in other cases such as other liver diseases or certain medications. After an ultrasound for liver complications of chronic alcoholism, monitoring of gamma-GT can be done while weaning the patient off of alcohol to decrease its levels in their blood.
