Which test is commonly used to evaluate liver function?

The ALT (alanine aminotransferase) test is a specific enzyme that is primarily found in the liver, making it a reliable indicator of liver function. When liver cells are damaged or injured, ALT is released into the bloodstream, leading to elevated levels in blood tests. This is why the ALT test is widely used in clinical practice to assess liver health and identify conditions such as hepatitis or liver cirrhosis.

In contrast, other tests listed serve different purposes. The creatinine test is primarily used to evaluate kidney function, the blood glucose test assesses blood sugar levels, and a complete blood count evaluates overall blood health but does not specifically provide insights into liver function. Therefore, the ALT test stands out as the most relevant choice for evaluating liver function.
