e
Serum gamma glutamyltransferase (GGT) is a sensitive indicator of alcohol use. ALT will be elevated in acetaminophen overdose and viral hepatitis. AST is raised in acute liver damage, but also seen in red blood cells, skeletal muscle, and cardiac muscle. Alkaline phosphatase elevation is seen in Pagetís disease. Direct bilirubin is elevated in bile duct obstruction by gallstones or cancer
