Measures inflammation in the body and helps identify infections and autoimmune conditions.
1.ESR (Erythrocyte Sedimentation Rate)
Measures how fast red blood cells settle in one hour. A raised value suggests inflammation somewhere in the body.
Also known as: ESR, Erythrocyte Sedimentation Rate, Sed Rate
The ESR test measures how quickly red blood cells settle at the bottom of a tube of blood in one hour. When there is inflammation in the body, red blood cells clump together and settle faster, which raises the ESR value.
ESR does not diagnose a specific condition. Doctors use it along with other tests and your symptoms to identify infections, autoimmune disorders and chronic inflammatory conditions, and to monitor how these conditions respond to treatment.
An ESR test may be recommended if you have:
No fasting is required.

Reference ranges can differ between labs. Your report shows the range used by the lab.
