This probably explains why at least one third of patients infected with hepatitis C virus have persistently normal serum ALT levels despite the presence of inflammation on liver biopsy.6,7 Patients with cirrhosis often have normal or only slightly elevated serum AST and ALT levels. Because factor VII has a short half-life of only about six hours, it is sensitive to rapid changes in liver synthetic function. Elevated liver enzymes are determined by taking a blood test, and are often a sign of liver damage from alcoholism and some types of prescription drugs. Typical ranges can vary between the sexes, based on age and at different laboratories.

The ALT distributions in males and nonwhites (i.e., blacks and Hispanics) tend to have a larger tail at the high end, so that more values fall above the upper limits of normal set for the average population.10,11. 1998-2023 Mayo Foundation for Medical Education and Research (MFMER).

Measurement of total bilirubin includes both unconjugated (indirect) and conjugated (direct) bilirubin. Rare individuals have chronically elevated AST levels because of a defect in clearance of the enzyme from the circulation.14 For both AST and ALT, the average values and upper limits of normal in patients undergoing renal dialysis are about one half of those found in the general population.15 Mild elevations of ALT or AST in asymptomatic patients can be evaluated efficiently by considering alcohol abuse, hepatitis B, hepatitis C and several other possible diagnoses (Table 2).5.
