Erythrocyte Sedimentation Rate (ESR)
The ESR test measures how fast red blood cells settle in a test tube, helping detect inflammation in the body.About Test
The Erythrocyte Sedimentation Rate (ESR) Test is a simple blood test used to detect inflammation in the body.
It measures how quickly red blood cells (erythrocytes) settle at the bottom of a test tube over one hour. Normally, red blood cells settle slowly. However, in the presence of inflammation, they settle faster.
While ESR does not diagnose a specific disease, it helps doctors identify and monitor conditions such as infections, autoimmune disorders, and chronic inflammatory diseases.
