Description: GGT is an enzyme found in many organs such as the kidney, spleen, and pancreas. However, the main source of GGT is the liver. GGT is used to help detect liver disease and bile duct obstructions. Elevated GGT levels may be caused by liver disease, congestive heart failure, alcohol consumption and/or other conditions. While increased levels may indicate that the liver is being damaged, it does not specifically point to what may be causing the injury.
