-Erythrocyte Sedimentation Rate (ESR) is the rate at which red blood cells precipitate in a period of one hour.
-This is a nonspecific test for inflammatory and lymphoproliferative disorders.
-To measure ESR, non coagulated blood is placed in an upright tube, the rate at which red blood cells fall is measured and expressed in millimeters per hour.
-Normal value of ESR is 3-7 mm/hr
-Pro sedimentation factor is fibrinogen and anti sedimentation factor is -ve charge on RBCs.
-ESR is raised in pregnancy, rheumatoid arthritis etc. and decreased in polycythemia, sickle cell anemia, hereditary spherocytosis, CHF.
It is used to find out the degree of inflammation in the blood depending on how fast the individuals blood settles after an hour.
