Glutamyl Transferase (GGT) – GGT levels are elevated in all types of liver illnesses. GGT levels are measured to diagnose and treat alcoholic cirrhosis, as well as primary and secondary liver cancers. In identifying obstructive jaundice, cholangitis, and cholecystitis, it is more sensitive than alkaline phosphatase, transaminases, and leucine aminopeptidase. GGT levels are normal in skeletal disorders, hence GGT in serum can be utilized to determine if a high alkaline phosphatase indicates a skeletal or hepatobiliary condition.
Fasting for 12 hours is required.
