Abstract :

MicroSED-10� (Electra Lab,Italy) is automated method for measurement of erythrocyte sedimentation rate (ESR). The aim of our study was to compare the ESR values by MicroSED-10� against the standard Westergren�s method. Study was conducted in outpatient department of pathology at P.D.U. MEDICAL COLLEGE & HOSPITAL-RAJKOT on 209 patients. The samples taken were as per the recommendations charted out by International Council for Standardization in Haematology (ICSH). Bland and Altman statistical analysis was applied for evaluation. The analysis revealed a low degree of agreement between the manual and automated method especially for higher ESR values[>25mm/hour],mean difference~2.58�9.17(95% limits of agreement,-15.39 to 20.55) as compare to lower ESR value[<25mm/hour],mean difference~1.22�1.90(95% limits of agreement,-2.50 to 4.94) & Over all whole ESR data analysis shows, mean difference~2.37�8.34(95% limits agreement,?13.94 to 18.68) for 1 hour. The fully automated system MicroSED-10� for ESR measurement tends to underestimate the manual ESR readings especially at higher ESR values.
