A Sedimentation Rate Test is a blood test used to detect inflammation in the body. It is not a stand-alone diagnostic tool because it cannot pin-point the cause of inflammation. It is combined with other tests to determine the cause of your symptom. Polymedco, Inc. can help you deliver value based medicine to your patients with the erythrocyte sedimentation rate (ESR) test.
