What is the Westergren ESR reference range for males?

The Westergren erythrocyte sedimentation rate (ESR) reference range for males is primarily accepted to be 0-15 mm/hr. This test measures the rate at which red blood cells settle in a tube over a given period, and it is used as a nonspecific marker of inflammation in the body. The reference range can vary slightly based on factors such as age and laboratory standards, but for adult males, 0-15 mm/hr is widely recognized as the standard.

Understanding the significance of the ESR is crucial; it helps in diagnosing conditions associated with acute and chronic inflammation, infections, and autoimmune diseases. Variations in the ESR reference ranges highlight the importance of laboratory protocols and individual patient considerations when interpreting test results.
