An Evaluation on Performance of SysmexXT-1800i Automated Hematology Analyzer

Wang Li-ping

Abstract

Objective:To evaluate the function of SysmexXT-1800i automated hematology analyzer. Methods:To examine the precision,carry over rate,linearity and total repeatability of SysmexXT-1800i,then compare its differential counts (DCs) of white blood cells with that obtained manually. Results:The precision,carryover rate,linearity and total repeatability were in the prescriptive range,and the correlation coefficients (r) between DCs of neutrophils,lymphocytes,monocytes,eosinophils,and basophils obtained by handiwork and the machine were 0.96,0.954,0.462,0.807,and 0.618,respectively. Conclusion:The main performance indexes of SysmexXT-1800i accord with the experimental requirements,which shows the machine is an ideal automated hematology analyzer.
