What does the acronym WNL signify in a medical report?

The acronym WNL stands for "Within Normal Limits." This phrase is commonly used in medical reports to indicate that a patient's test results, physical examination findings, or vital signs fall within the established normal range for a healthy population. When healthcare professionals document that values are WNL, it suggests that there are no significant abnormalities present that would require further examination or intervention. This terminology helps in efficient communication among medical staff regarding the patient's health status. Using this standardized language also helps to maintain clarity and consistency in medical documentation.
