Which laboratory value would indicate liver dysfunction?

Elevated liver enzymes such as AST (aspartate aminotransferase) and ALT (alanine aminotransferase) are key indicators of liver dysfunction. These enzymes are primarily found in the liver, and their release into the bloodstream typically signifies that liver cells are damaged or inflamed. Conditions such as hepatitis, fatty liver disease, or cirrhosis can cause these enzymes to rise. Monitoring these levels is crucial in diagnosing and managing liver-related illnesses.

In contrast, serum creatinine typically reflects kidney function rather than liver health, while low hemoglobin indicates potential anemia, which might not specifically correlate with liver dysfunction. An increased white blood cell count often points to infection or inflammation rather than direct liver impairment. Thus, the elevation of liver enzymes serves as a reliable marker for assessing the state of liver health.
