Blood analyzer Sysmex XN-9000 testing in low whole blood platelet performance evaluation / 中国医学装备

ABSTRACT

Objective:To evaluate the performance of Sysmex XN-9000 automatic blood analyzer (hereinafter referred to as XN-9000) in whole blood with the low platelet (PLT). Methods:A total of 48 whole blood samples with platelet count less than 70×109/L were randomly collected from XN-9000 correlation analysis to evaluate XN-9000 the accuracy and precision of detection in low whole blood PLT and carry pollution rate, use XN-9000 and microscope count, respectively.Results: XN-9000 detection in low whole blood PLT between batch and batch of CV% 1.13% and 1.29%, respectively; XN-9000 with microscope PLT count results have high correlation, The regression equation forY=0.917X+3.217,correlation coefficientr=0.964; XN-9000 detection in low whole blood PLT carry pollution at a rate of 0.12%. Detection accuracy of PLT Bias, %(-1.25%~1.8%); Linear range(0~1206)×109/L; Clinical reportable range (0~6030)×109/L.Conclusion: The detection of XN-9000 blood analyzer is in low whole blood PLT has high precision and accuracy, carry pollution rate is extremely low, the result has the reliability, can be directly applied to clinical.
