Elevated Erythrocyte Sedimentation Rate (ESR)
Definition
Elevated erythrocyte sedimentation rate (ESR) is a non-specific laboratory test that measures the rate at which red blood cells (erythrocytes) settle in a test tube over a period of one hour. An increased ESR indicates the presence of inflammation or other abnormal conditions in the body, but it does not provide information about the specific cause or location of the problem.
