What is the primary function of hepatic function tests?

The primary function of hepatic function tests is to evaluate liver health. These tests measure various substances produced by the liver, including enzymes, proteins, and bilirubin, which can indicate how well the liver is functioning and whether there are any liver diseases or conditions present. By analyzing the levels of these substances in the blood, healthcare providers can gain insights into potential liver damage, inflammation, or cholestasis (a condition where bile cannot flow from the liver to the duodenum).

Monitoring enzyme levels such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST) helps assess liver cell integrity, while tests for alkaline phosphatase (ALP) and bilirubin can help determine bile duct obstruction or liver-specific conditions. Therefore, hepatic function tests play a crucial role in diagnosing and managing liver-related health issues.

The other choices focus on different bodily functions. Assessing kidney function, measuring blood glucose, and checking for infections pertain to other organ systems or conditions and do not relate directly to the evaluation of liver health.
