Sed Rate (ESR) for a male under 50 is typically within which range?

• A. 0-15 mm/hr
• B. 0-10 mm/hr
• C. 0-20 mm/hr
• D. 5-15 mm/hr

Answer: (A)

ESR reference ranges depend on age and sex. For a male under 50, the typical upper limit is about 15 mm/hour. Healthy young men usually have ESR values at or below this level, while higher values can suggest inflammation or other processes (though ESR alone isn’t diagnostic). A range up to 10 would miss many normal values in the 11–15 range, and a range up to 20 would be too permissive for this group. A lower bound of 5 excludes normal low values seen in healthy people. So, 0–15 mm/hr best reflects the normal range for a man under 50.
