Liver Function
The liver function panel groups chemistry markers related to hepatocellular injury, cholestatic enzyme activity, bilirubin handling, and circulating proteins. It includes ALT, AST, alkaline phosphatase, GGT, bilirubin, albumin, total protein, and calculated globulin.
Frequently Asked Questions
Why are ALT and AST shown alongside alkaline phosphatase and GGT?
ALT and AST are commonly used for hepatocellular injury, while alkaline phosphatase and GGT help identify cholestatic or biliary patterns. The combined pattern is more informative than a single enzyme.
Why do bilirubin and albumin belong on the same liver page?
They add different kinds of context. Bilirubin reflects pigment handling, while albumin, total protein, and calculated globulin describe different parts of the circulating protein profile.
