The erythrocyte sedimentation rate. Guidelines for rational use.

Area of Science:

• Clinical pathology
• Diagnostic testing

Background:

• The erythrocyte sedimentation rate (ESR) is a common blood test.
• Its utility as a standalone diagnostic tool is often debated.

Purpose of the Study:

• To evaluate the diagnostic value of ESR in various clinical scenarios.
• To determine the effectiveness of ESR in screening and monitoring diseases.

Main Methods:

• Review of clinical utility of ESR.
• Analysis of ESR in asymptomatic individuals and specific diseases.

Main Results:

• ESR is not a useful screening test for asymptomatic persons.
• Unexplained ESR elevations are typically transient and not indicative of serious illness.
• ESR is most valuable for diagnosing temporal arteritis and monitoring treatment response.
• ESR has limited diagnostic value in rheumatoid arthritis but can aid in monitoring disease activity.
• ESR is often normal in cancer, infection, and connective tissue diseases, limiting its use in excluding these conditions.

Conclusions:

• ESR is most useful in specific conditions like temporal arteritis.
• ESR has limited utility as a general screening tool or for excluding common diseases.
• Clinical correlation with patient history and physical examination is crucial when interpreting ESR results.
