摘要
Abstract
Objective:To evaluate the performance for the Sysmex XN20 A1 automation blood cell analyzer.Methods: The precision, contaminative rate, linear range, blank, accuracy and various sample models were verified, and low values of blood platelet were compared with the methods of microscopy and dye.Results:The contaminative rate was lower than 0.4%. The linear arrange and precision were well for the analyzer. The values of RBC, HGB and PLT were within the range of 1±0.05 and the correlation coefficients were higher than 0.975. The bias of average and constant values by the accuracy verification samples test met the demands of accuracy. And the relative differences of various sample models meet the requirements of the comparability. The variable coefficient of low values of PLT was lower than 4% by the dye method.Conclusion: The Sysmex XN20 A1 automation blood cell analyzer has the characteristics of perfect precision, accuracy, low contaminative rate, broad linear arrange and good repeatability for the low level PLT. It can be applied in clinical laboratory.关键词
