Evaluation of Sysmex Hematology Analyzers with Fresh Blood / 现代检验医学杂志

ABSTRACT

Objective To investigate comparability between Sysmex different hematology analyzers.The consistency of all he-matology analyzers with the same fresh sample.Methods Selected Sysmex XE-2100 as reference instrument which attend external quality assessment.Fresh high,medium and low blood were detected in Sysmex XS-800i,Sysmex XT-4000i and Sys-mex XT-1800i,compared results of WBC,RBC,HGB,HCT,MCV and PLT.Results The bias of XS-800i and XE-2100 was WBC 2.85%,RBC 1.44%,HGB 0.75%,HCT 2.11% and PLT 5.53%.The bias of XT-4000i and XE-2100 was WBC 1.26%,RBC 0.95%,HGB 0.68%,HCT 1.35% and PLT 2.68%.The bias of XT-1800i and XE-2100 was WBC 5.21%, RBC 1.96%,HGB 1.60%,HCT 1.96% and PLT 4.95%.It had good compatability.All various parameters was in the al-lowed range.Conclusion Should maintenance and compare the hematology analyzers periodically,found the problem then calibration instruments in time,ensure the consistency of measurement results between different instruments and guarantee accuracy of the results.
