Liver Function Tests

GGT is raised when there is bile obstruction or inflammatory conditions that produce more unconjugated bilirubin than the liver can handle. Albumin is made in the liver so low levels indicate liver disease or bile duct blockage. ALP rises more than ALT in liver damage and hepatitis, while ALT and AST indicate inflammation and cell death in the liver.
