The assessment of liver function is primarily monitored through the levels of certain enzymes, with aspartate aminotransferase (AST) and alanine aminotransferase (ALT) being two of the most important. These enzymes are found predominantly in the liver and are released into the bloodstream when liver cells are damaged or inflamed. Elevated levels of AST and ALT indicate potential liver conditions such as hepatitis, cirrhosis, or fatty liver disease, making them key indicators for evaluating hepatic function and integrity.

Monitoring these enzyme levels allows healthcare providers to assess the state of the liver more effectively than other values. For instance, blood urea nitrogen (BUN) and serum creatinine levels are primarily used to evaluate kidney function, while white blood cell counts are indicative of infection or inflammation rather than liver health. Thus, measuring AST and ALT provides direct insight into liver damage and helps guide further investigative and therapeutic approaches.
