Abstract Objective To verify and evaluate the performance of SysmexXN9000 automatic hematology analyzer with two analysis modules. Methods According to “Health Standard of the People′s Republic of China WS/T406-2012”, performance of SysmexXN9000 (A1+B4) automatic blood analyzer for complete blood count, leukocyte classification, reticulocyte count, etc was verification and evaluated. Results Blank counting, carrying contamination rate, precision (within and between batches), accuracy and linearity all meet the standard requirements. Leukocyte classification and reticulocyte were correlated with manual count (P ＜ 0.01), and the correlation coefficients of A1 and B4 modules were 0.675 and 0.678, respectively, which were smaller than other parameters. Conclusion The SysmexXN9000 (A1+B4) automatic blood analyzer has good performance and high clinical value.
