摘要
目的：评价日本SYSMEX生产的XT-4000i多功能全自动血细胞分析仪（以下简称XT-4000i分析仪）体液模式的性能。方法采用XT-4000i分析仪分别检测体液模式下各项参数（WBC和RBC ）的精密度、准确度、携带污染、仪器测定线性验证。结果 WBC-BF精密度为0．90％～5．54％，RBC-BF精密度为1．13％～5．13％。携带污染率WBC、RBC分别为0．09％、0．14％；仪器有较宽的WBC和RBC的检测线性；仪器测定与手工镜检的比较结果均满足要求。结论 XT-4000i分析仪体液模式各性能均符合仪器的要求范围，可用于临床体液分析检测。
Objective To evaluate the performance of the body fluid mode on the automatic analysis system-XT-4000i .Methods XT-4000i analyzer was used to detect the precision ,accuracy ,carryover rate ,meanwhile to validate the detection limit of the pa-rameters（WBC and RBC） .Results The range of the precision for WBC-BF was 0 .90% -5 .54% ,for RBC-BF was 1 .13% -5 .13% .The carry over rates were 0 .09% for WBC and 0 .14% for RBC ,respectively .As for as the analyzer range ,the results of the linearity and the detection limit verification were in line with the requirements of the analyzer ;the comparison between the man-ual microscopy results and the analyzer results meet the requirements of XT-4000i analyzer .Conclusion The performance of XT-4000i analyzer is in line with the requirements of the instrument range ,which can be used for clinical body fluid analysis and detection .
