Erythrocyte Sedimentation Rate (ESR)
Erythrocyte sedimentation rate (ESR or sed rate) is a test that indirectly measures the degree of inflammation. Inflammation is part of the body’s immune response. It can be acute, which can show an increase in value after trauma, injury or infection. If the ESR is elevated for a long period of time, then it could be seen in conditions like autoimmune disease or cancer. The ESR is used as a screening test and not diagnostic, it provides general information about possible presence of an inflammatory condition. The ESR test has also been good indicator for diagnosis and monitoring of the following diseases, temporal arteritis, polymyaglia rheumatica, and systemic vaculitis.
