Objective To evaluate the main performance of Sysmex XN-9000 fully-automatic blood and body fluid analyzer. Methods According to the guidelines EP15-A2 and EP6-A2 of clinical and laboratory standards institute (CLSI), the precision, contamination rate, linearity range and accuracy of XN-9000 analyzer were verified based on the detection results of Beckman LH750 full-automatic blood analyzer which were choosed as assessment basis. Then the verification results of XN-9000 analyzer were compared with performance indicators declared by its manufacturer or recognized quality standards. Results The intra-assay and inter-assay coefficient variations (CV%) of major parameters including WBC, RBC, HGB, HCT and PLT measured by XN-9000 analyzer were 0.11%~2.42% and 0.12%~2.50%, respectively. The correlation coefficient (r ) of linear correlation analysis between observational values and theoretical values of the above parameters was 0.99991~0.99999 while the contamination rate of the above parameters was 0.00%~0.38%. The correlation coefficient (r ) of comparative correlation analysis between the detection indicators of XN-9000 analyzer and those of Backman LH750 analyzer was greater than 0.999. The Bias of accuracy verification of the above parameters of XN-9000 analyzer was -0.67%~0.96%. Conclusion The main parameters including precision, contamination rate, linearity range and accuracy of XN-9000 analyzer can meet the requirements of relevant standards.
