Gamma-Glutamyl Transferase (GGT) details
What Gamma-Glutamyl Transferase (GGT) shows
Gamma-glutamyl transferase (GGT) is a liver enzyme particularly sensitive to bile duct problems and to alcohol consumption, often rising with even moderate regular drinking. It's frequently used alongside alkaline phosphatase (ALP) to help clarify the source of an elevated ALP: since GGT rises with liver/bile duct causes but not with bone-related causes, a normal GGT alongside high ALP points toward a bone source, while an elevated GGT supports a liver or bile duct explanation. GGT can also be a sensitive but nonspecific general marker of liver stress, so it's usually interpreted together with the fuller liver panel.
