Frontiers | Imaging Erythrocyte Sedimentation in Whole Blood
Introduction. The erythrocyte sedimentation rate (ESR) is one of the oldest diagnostic methods. Already in ancient times it was known that the sedimentation of the red part of the blood can be very different (Kushner, 1988).In fact, it was known even before the thermometer was invented that many diseases cause a higher ESR (Bernhardt and …
