ESR (Erythrocyte Sedimentation Rate)

The ESR is the speed at which non-clotted red blood cells settle to the bottom of a test tube.

Increased rates of RBC settling are caused by changes in the plasma proteins. In some diseases, the ESR can be particularly rapid (high ESR). These include:

  • Infection
  • Inflammatory diseases
  • Auto-immune diseases
  • Trauma/tissue injury
  • Many cancers

Normal Values*

Men 0-15 mm/hr
Women 0-20 mm/hr
Children 0-10 mm/hr

*These are general values taken from a variety of sources. The actual normal values may vary from lab to lab and from one type of testing protocol to another.
