The erythrocyte sedimentation rate (ESR) is a nonspecific test that can indicate tissue necrosis and inflammation. It measures the rate at which red blood cells settle in a test tube over a period of one hour. In conditions such as infections or tissue necrosis, the ESR is usually elevated due to the increase in certain proteins in the blood that cause the red blood cells to clump together and settle faster. Therefore, an elevated ESR is a useful indicator of acute infections related to tissue necrosis.
