The Evaluation of Performance of Sysmex xs-1000i Blood Cell Analyzer

Objective To evaluate the function of Sysmex xs-1000i blood cell analyzer.Methods We have done a series of tests with Sysmex xs-1000i haematology analyzer fo r precision,linear range,contamination rate,comparability and ability of scring abnormal specimens.Results The variation coefficent of Sysmex xs-1000i within batches and between bathes,reproducibility were all 5 %.Carryover 1.0 %.Excellent relevance was observed in determination of white blood cell, red blood cell,hemoglobin,and platelet as compared with Sysmex XE-2100: r 0.99.The results of WBC lassfication were related to which analysed by manual method,the data of r were between 0.519 to 0.986.The specificity of screen to abnormal morphology cells was 91.2 %.And the linear range was wider.Conclusion The function of Sysmex xs-1000i blood cell analyzer is fine,it can screen sample quickly and efficiently.
