What Is Your Sedrate?

Why Your Doctor Ordered This Blood Test


Updated May 23, 2014

Definition: A sedrate, also referred to as the erythrocyte sedimentation rate or ESR, is a blood test used to determine if an abnormal level of inflammation exists in the body, but it is nonspecific regarding the cause.

The test measures the rate at which red blood cells fall to the bottom of a tube over time. An elevated sedrate corresponds to increased inflammation in the body. (Full Explanation of Sedimentation Rate)
