Description

ESR is a blood test that measures the rate at which red blood cells settle at the bottom of a test tube over a period of one hour. It is a simple and non-specific test used to detect the presence of inflammation in the body.

An increased ESR indicates that there may be inflammation due to infections, autoimmune conditions, or other medical disorders, while a normal or low ESR usually suggests the absence of significant inflammation.

Overall, ESR is used as a supportive test to help in the diagnosis and monitoring of various inflammatory and disease conditions rather than providing a specific diagnosis.
