MEK-7222K 血细胞分析仪器性能评价

摘要

目的：评估M EK‐7222K血细胞分析仪的各项性能参数是否符合相关要求，能否应用临床。方法以M EK‐7222K血细胞分析仪作为评价仪器，分别进行空白检测、批内和批间精密度测试、携带污染率测试、线性验证，并将M EK‐7222K血细胞分析仪全血白细胞计数结果与显微镜手工分类计数结果进行比对，评估仪器的测量准确度。结果仪器的空白值、批内精密度、批间精密度、携带污染率均满足要求；线性验证通过；白细胞分类合格率满足白细胞分类计数准确度的要求。结论 M EK‐7222K血细胞分析仪的各项性能参数符合要求，可应用于临床。%Objective To assess the whether the performance parameters of MEK‐7222K hematology analyzer conforming to the related requirements and applying in clinic .Methods MEK‐7222K hematology analyzer was used as the target analyzer .The blank test ,intra‐batch and inter‐batch precision test ,carryover rate test and linear verification were respectively performed .The whole blood WBC count detection results were compared between the MEK‐7222K hematology analyzer and the microscopic manual count for evaluating the accuracy of instrument measurement .Results The MEK‐7222K hematology analyzer met the requirements in the blank value ,intra‐batch precision ,inter‐batch precision and carryover rate ;the linear validation was passed ;the qualification rate of WBC classification met the accuracy requirement of WBC classification count .Conclusion The various performance parameters of the M EK‐7222K hematology analyzer meet the requirements and can be used in clinic .
