Description
The Erythrocyte Sedimentation Rate (ESR), Westergren Method, is a blood test that measures how quickly red blood cells settle at the bottom of a test tube over a specific period. A faster-than-normal rate may indicate the presence of inflammation or infection in the body.
The ESR test is commonly used alongside other diagnostic tools to monitor autoimmune diseases, chronic inflammatory conditions, and infections.
Purpose of the Test
- Detect inflammation in the body
- Monitor autoimmune disorders such as rheumatoid arthritis or lupus
- Evaluate chronic infections or inflammatory conditions
- Assess response to therapy in inflammatory diseases
- Support diagnosis of conditions causing unexplained fatigue, fever, or joint pain
Who Should Consider This Test?
- Individuals with joint pain, swelling, or stiffness
- Patients with autoimmune conditions or suspected inflammatory disorders
- People with chronic infections or unexplained symptoms
- Healthcare providers monitoring treatment response in inflammatory or autoimmune disease
What the Test Measures
- Erythrocyte Sedimentation Rate (ESR):
- Measures the rate at which red blood cells settle in a tube over one hour.
Elevated ESR may indicate inflammation, infection, or autoimmune activity.
Normal ESR typically suggests low or no significant inflammatory activity.
Note: ESR is a non-specific test and is usually interpreted along with other laboratory and clinical findings.
Fasting Required?
No fasting required.
