VesMATIC 20/20 PLUS TM is an automated method for measurement of erythrocyte sedimentation rate (ESR) used widely in many laboratories.Aims:The aim of our study was to compare the ESR values provided by VesMATIC 20/20 PLUS TM against the modified Westergren method.Materials And Methods:This cross-sectional study was conducted at the Clinical laboratory in Kasturba Hospital, Manipal on 100 patients. The samples taken were as per the recommendations charted out by International Council for Standardization in Hematology (ICSH) for comparing automated and manual Westergren method.Statistical Analysis Used:Bland and Altman statistical analysis was applied for evaluating VesMATIC 20/20 PLUS TM with the conventional Westergren method.Results:The analysis revealed a low degree of agreement between the manual and automated methods especially for higher ESR values (25mm/hr). This discrepancy was less evident for ESR values in the normal range <25 mm/hour.Conclusions:The fully automated system Ves MATIC 20/20 PLUS TM for ESR measurement tends to underestimate the manual ESR readings.Further studies and validation experiments would be required.
