Erythrocyte Sedimentation Rate Test Overview

What is the Erythrocyte Sedimentation Rate (ESR) Test?

The Erythrocyte Sedimentation Rate (ESR) test measures how quickly red blood cells settle at the bottom of a test tube over one hour. It is a non-specific indicator of inflammation in the body and can help detect conditions such as infections, autoimmune diseases, and chronic inflammatory disorders.

An elevated ESR may indicate the presence of inflammation due to conditions like rheumatoid arthritis, lupus, infections, or certain cancers. Conversely, a lower-than-normal ESR could be associated with conditions such as polycythemia or abnormal red blood cell shapes.

This test is commonly used alongside other laboratory tests to monitor disease activity, assess treatment response, or investigate unexplained symptoms such as persistent fatigue, fever, or joint pain. Understanding ESR levels can help doctors make informed decisions about further diagnostic tests or interventions and manage underlying inflammatory conditions effectively.

Why Take the Erythrocyte Sedimentation Rate (ESR) Test?

This test is recommended if you:

• Have unexplained persistent fever, fatigue, or joint pain

• Are being monitored for autoimmune or inflammatory conditions like rheumatoid arthritis or lupus

• Need assessment for chronic infections or inflammatory disorders

• Want to track response to treatment for a known inflammatory condition

How is the Erythrocyte Sedimentation Rate (ESR) Test Carried Out?

• A small blood sample is drawn from a vein in your arm.

• The sample is placed in a vertical tube, and the rate at which red blood cells settle is measured over one hour in the lab.

• The test is simple, quick, and minimally invasive.

How do I Prepare for the Erythrocyte Sedimentation Rate (ESR) Test?

• Diet: No special dietary restrictions; drink water as usual.

• Activity: No limitations; maintain your normal routine.

• Medications: Inform your doctor if you are taking drugs that may affect inflammation or red blood cells.

Next Steps

If abnormal ESR levels are detected, your doctor may:

• Recommend additional tests to identify the underlying cause of inflammation (e.g., CRP, autoimmune panels)

• Assess disease activity or progression in chronic inflammatory conditions

• Adjust medications or treatments as needed

• Monitor ESR periodically to evaluate treatment response
