Clinical Utilities

ESR results become elevated due to the formation of erythrocyte rouleaux ,which is caused mainly by alterations in plasma and erythrocyte factors.  Erythrocyte sedimentation is accelerated by an increase in the plasma concentration of "acute phase proteins", which are elevated in acute tissue damage, chronic infection, chronic inflammation, and pregnancy.
