blood gamma-glutamyltransferase activity level +
The amount of enzymatic activity of gamma-glutamyltransferase (GGT) in a specified sample of blood. GGT catalyzes the transfer of the gamma-glutamyl moiety of glutathione to an acceptor such as amino acid, a peptide or water. Blood GGT level is used as an enzymatic marker for liver disease or damage.
