Abstract:
Objective:To evaluate the performance of Sysmex company's new product Sysmex XN-9000 automatic blood fluid analyzer and confirm the test results. Methods: According to the American association of clinical laboratory standardization guidelines EP15-A2, the EP6-A2 requirements for Sysmex XN-9000 blood analyzer for precision, carry pollution rate, linear range and accuracy verification, to Backman LH750 comparison results for evaluating the basis, the results and the performance of manufacturer's statement or recognized quality standards. Results:XN-9000 blood analyzer determination of white blood cell (WBC), red blood cell (RBC), hemoglobin (HGB), RBC deposited (HCT) and platelet (PLT) the main parameters in the batch coefficient of variation (CV%) of 0.11%~0.11%, between the group of CV% of 0.12%~0.12%, linear correlation r is 0.99991~0.99999, carry pollution rate was 0.00%~0.38%, the correlation analysis of each index r>0.999, the indicators accuracy verification bias of 0.67~0.67. Conclusion: XN-9000 instrument for determination of main parameters of precision, accuracy, linear, carrying pollution rate and other major evaluation indexes meet the requirements, test results can be used for clinical diagnosis and treatment of related diseases and curative effect judgment.
