An ESR (Erythrocyte Sedimentation Rate) test, also called sed rate, measures how quickly red blood cells settle to the bottom of a test tube. Faster settling indicates inflammation in the body.
What This Test Measures
Erythrocyte Sedimentation Rate (ESR):
When inflammation is present, proteins released into the blood cause red blood cells to clump together and fall faster. ESR is a nonspecific marker – it detects inflammation but not the cause.
Reference Ranges
• Men under 50: 0-15 mm/hr
• Men over 50: 0-20 mm/hr
• Women under 50: 0-20 mm/hr
• Women over 50: 0-30 mm/hr
Who Should Consider This Test
• Symptoms of inflammatory conditions
• Monitoring autoimmune diseases (rheumatoid arthritis, lupus)
• Unexplained fever or fatigue
• Joint pain or stiffness
• Suspected infections
• Monitoring response to treatment
What Elevated ESR May Indicate
Inflammatory Conditions:
• Rheumatoid arthritis
• Lupus
• Inflammatory bowel disease
• Temporal arteritis
• Polymyalgia rheumatica
Infections:
• Bacterial infections
• Tuberculosis
• Endocarditis
Other:
• Cancer
• Kidney disease
• Anemia
• Pregnancy
ESR vs. CRP
Both measure inflammation, but:
• ESR changes more slowly (days to weeks)
• CRP changes rapidly (hours)
• ESR is better for monitoring chronic conditions
• CRP is better for detecting acute inflammation
