WNL (within normal limits)
WNL, or "within normal limits," is a term widely used in the medical field to describe test results, vital signs, or physical exam findings that fall within the range considered normal for a healthy individual. Healthcare providers use this term during patient evaluations to quickly convey that certain measurements or observations do not indicate any abnormalities that require further investigation or intervention. For instance, a blood pressure reading or liver function test result that is WNL would suggest that these aspects of a patient’s health are stable and unremarkable.
This term helps streamline communication among healthcare professionals by providing a simple and standard way to document normalcy. It’s a part of everyday medical vocabulary, providing reassurance to patients while expediting clinical decision-making. By indicating that everything is as expected for a person's age, gender, or specific health conditions, WNL helps narrow down the focus to any areas that may require additional attention.
Patients often hear "within normal limits" during routine check-ups or after labs and tests, reinforcing that their health metrics are on track. It is a useful, shorthand way for both doctors and patients to gauge overall health quickly.
