What is Erythrocyte Sedimentation Rate?
Erythrocyte Sedimentation Rate (ESR) is a laboratory test that measures the rate at which red blood cells settle at the bottom of a test tube over a specified period. It is a common test used to detect inflammation in the body.
How is ESR Measured?
The test involves drawing a small amount of blood from the patient and placing it in a tall, thin tube. The rate at which the red blood cells fall is measured in millimeters per hour (mm/hr). Higher rates typically indicate the presence of inflammation or other medical conditions.
Why is ESR Important?
ESR is a valuable diagnostic tool that helps physicians identify and monitor various conditions, including infections, autoimmune diseases, and cancers. It is often used alongside other tests to provide a comprehensive view of a patient’s health.
