Which of the following is not typically part of a standard liver function panel?

Creatine kinase is a marker of muscle injury, not liver function. A standard liver function panel is designed to assess hepatocellular injury and biliary function, so it includes enzymes like ALT and AST (which come from liver cells), GGT (biliary involvement), and often alkaline phosphatase, along with bilirubin and albumin. Since CK reflects muscle energy and damage rather than liver health, it isn’t routinely included in this panel. If there’s a concern about muscle injury or a heart issue, CK might be ordered separately, but it doesn’t belong in the typical liver function assessment. The other choices are enzymes commonly used to evaluate the liver, making them appropriate for a liver function panel.
