GGT is an enzyme found in the liver and bile ducts. It's one of the most sensitive markers for liver and bile duct problems. GGT is particularly useful for detecting alcohol-related liver damage and bile duct obstruction. It's often ordered alongside other liver enzymes to help differentiate between liver and bone sources of elevated alkaline phosphatase.
