What is analysed?
Erythrocyte Sedimentation Rate (ESR) measures the rate at which red blood cells settle in a vertical column of blood over a certain period, typically one hour.
What does the result mean?
The result indicates the degree of inflammation or tissue damage in the body. Higher ESR values often correlate with inflammatory conditions, infections, autoimmune diseases, and certain cancers.
Why undergo the analysis?
ESR analysis helps in diagnosing and monitoring various inflammatory and autoimmune diseases, as well as assessing response to treatment.
When to undergo the analysis?
ESR analysis may be recommended when investigating symptoms of inflammation, such as persistent fever, unexplained weight loss, fatigue, joint pain, and swelling.
What sample is required?
A blood sample is required for ESR analysis.
Is any prior preparation necessary?
No specific preparation is required before the blood test. However, informing the healthcare provider about any medications or supplements being taken is advisable.
How is it used?
ESR is used as a non-specific marker of inflammation, aiding in the diagnosis and monitoring of various medical conditions.
What are the normal values?
Normal ESR values vary by age and gender but are typically lower in men and increase with age. In general, normal ESR values are below 20 mm/hr for men and below 30 mm/hr for women.
Erythrocyte Sedimentation Rate (ESR) Reference Table
| Age group | Normal ESR range (mm/hr) |
| Men | Below 20 |
| Women | Below 30 |
This table provides a reference for interpreting Erythrocyte Sedimentation Rate (ESR) values based on age and gender, assisting healthcare professionals in diagnosing and managing inflammatory conditions effectively.
What do altered values signify?
Elevated ESR values suggest the presence of inflammation or tissue damage. However, ESR alone cannot diagnose a specific condition and requires further evaluation in conjunction with other clinical and laboratory findings.
