Which of the following lab results is commonly associated with liver function?

The correct answer is commonly associated with liver function because ALT, or alanine aminotransferase, is an enzyme found predominantly in the liver. It plays a critical role in the metabolism of amino acids, and its levels in the blood are used as a key indicator of liver health. When liver cells are damaged or inflamed, as seen in conditions like hepatitis or cirrhosis, ALT is released into the bloodstream, leading to elevated levels. Therefore, measuring ALT is a standard practice in assessing liver function and identifying liver-related issues.

The other choices are related to different aspects of bodily functions. BUN (Blood Urea Nitrogen) is primarily used to evaluate kidney function. Creatinine is also a marker for kidney health, reflecting renal function and muscle metabolism. Glucose levels are associated with carbohydrate metabolism and are primarily used in the context of diabetes management or assessing metabolic diseases. None of these are specific indicators of liver function like ALT is.
