GGT is an enzyme found mainly in the liver; it is very sensitive to changes in liver function. It is normally present in low levels in the blood. When the liver is injured or obstructed, the GGT level rises. It is the most sensitive liver enzyme in detecting bile duct problems. A rise in GGT can occur even when there is no identifiable cause that is related to liver disease.
