The Erythrocyte Sedimentation Rate (ESR) test is a blood test that measures the distance that red blood cells settle in a tube in one hour. An adjusted ESR helps account for factors like age and gender.

This test is often used as a screening tool to detect inflammation associated with conditions such as infections, cancers, and autoimmune diseases. However, it cannot pinpoint the exact cause of inflammation.

The reference range for ESR is typically between 0–20 mm/hr, but it can vary based on individual factors. Elevated levels may prompt further diagnostic testing to identify the underlying condition.

Frequently asked questions

What conditions can cause an elevated ESR?
Conditions such as infections, rheumatoid arthritis, systemic lupus erythematosus, and some cancers can cause elevated ESR levels.
Is ESR testing specific for any disease?
No, ESR is a non-specific marker of inflammation and cannot diagnose a specific disease on its own.
