ESR, EDTA Blood – E0005
Test Overview
The Erythrocyte Sedimentation Rate (ESR) test measures how quickly red blood cells settle at the bottom of a test tube over a specified period. It is a simple, non-specific blood test used to detect inflammation in the body.
This test helps identify underlying conditions associated with acute or chronic inflammation.
Why This Test is Important
