目的：评价Sysmex XN-9000全自动血液分析仪检测全血中低值血小板(PLT)的性能。方法：随机收集XN-9000检测全血PLT计数＜70×109/L的临床标本48份，分别用XN-9000和显微镜计数，通过对两种方法所测得的结果进行相关性分析，评价XN-9000检测全血中低值PLT的精密度、相关性、准确度、携带污染率、线性范围以及临床可报告范围。结果：XN-9000检测全血中低值PLT的批内和批间CV%分别为1.13%和1.29%；XN-9000与显微镜PLT计数结果具有高度相关性，回归方程为Y=0.917X+3.217，相关系数r=0.964；XN-9000检测全血中低值PLT的携带污染率为0.12%；检测PLT的正确度(Bias%)为-1.25%～1.80%；线性范围为(0～1206)×109/L；临床可报告范围为(0～6030)×109/L。结论：XN-9000血液分析仪检测全血中低值PLT具有很高的精密度和准确度，携带污染率极低，结果具有可靠性，可直接应用于临床。
目的：評價Sysmex XN-9000全自動血液分析儀檢測全血中低值血小闆(PLT)的性能。方法：隨機收集XN-9000檢測全血PLT計數＜70×109/L的臨床標本48份，分彆用XN-9000和顯微鏡計數，通過對兩種方法所測得的結果進行相關性分析，評價XN-9000檢測全血中低值PLT的精密度、相關性、準確度、攜帶汙染率、線性範圍以及臨床可報告範圍。結果：XN-9000檢測全血中低值PLT的批內和批間CV%分彆為1.13%和1.29%；XN-9000與顯微鏡PLT計數結果具有高度相關性，迴歸方程為Y=0.917X+3.217，相關繫數r=0.964；XN-9000檢測全血中低值PLT的攜帶汙染率為0.12%；檢測PLT的正確度(Bias%)為-1.25%～1.80%；線性範圍為(0～1206)×109/L；臨床可報告範圍為(0～6030)×109/L。結論：XN-9000血液分析儀檢測全血中低值PLT具有很高的精密度和準確度，攜帶汙染率極低，結果具有可靠性，可直接應用于臨床。

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.
