ESR Pipette
The erythrocyte sedimentation rate (ESR), also called a sedimentation rate or Westergren ESR, is the rate at which red blood cells sediment in a period of one hour.
It is a common hematology test, and is a non-specific measure of inflammation.
To perform the test, anti-coagulated blood is placed in at upright tube, known as a Westergren tube, and the rate at which the red blood cells fall is measured and reported in mm/h.
