ABSTRACT
EVALUATION OF LIVER FUNCTION ■ Several lab tests evaluate the presence of liver damage or
impairment of liver function. These tests are loosely termed “liver function tests.”
■ It can be helpful to subcategorize liver function tests to reflect specific patterns of liver injury: ▲ Markers of cholestasis ▲ Markers of hepatocellular injury ▲ Markers of biosynthetic function
■ Commonly used liver function tests and their normal values are listed in Table 1. ▲ Normal values can vary with age, sex, ethnicity, and body
mass index and are determined by the lab of each institution.
