What are the normal reference values for aspartate aminotransferase (AST)?

The reference values for aspartate aminotransferase (AST) are crucial for diagnosing and monitoring liver conditions and other health issues. The correct range of 0-35 units/L indicates the normal levels of AST that can typically be expected in a healthy adult.

When assessing AST levels, it's important to recognize that elevated levels can indicate liver damage, heart problems, or muscle disorders. The reference range can vary slightly among different laboratories due to variations in testing methods and population demographics, but the commonly accepted upper limit is around 35 units/L. This range helps healthcare professionals identify abnormal elevations that may warrant further investigation.

The other ranges provided do not align with the standard reference values established by medical guidelines. While they provide numerical values, they exceed the normal limits typically recognized in clinical practice, which can lead to misinterpretation of patient health status.
