Liver tests are unreliable guides to the presence or absence of fatty liver disease. Implementing these strategies may help lower ALT levels. Recent studies have identified a single nucleotide pleomorphism near the IL28B gene that can predict the response to treatment in hepatitis C.

Elevations of the unconjugated bilirubin level when the conjugated bilirubin level remains normal may also indicate an increased load of bilirubin caused by hemolysis.
