摘要(Abstract):

目的:应用极差分析法对4台检测原理相同的Sysmex全自动血细胞分析仪进行比对,探讨检测结果的可比性。方法:依据极差检验可比性方案,选择合适浓度标本,在4台编号分别为J-724-LJ、J-727-LJ、J-729-LJ、J-734-LJ的血细胞分析仪上检测WBC、RBC、Hb、HCT、MCV、MCH及MCHC、PLT,记录测定结果,计算极差,进行比对。结果:Sysmex全自动血细胞分析仪J-734-LJ的RBC、HCT、MCH、MCHC检测结果偏高,超出允许范围;排除来自仪器J-734-LJ的极端值后重新计算比对,J-724-LJ、J-727-LJ、J-729-LJ三台仪器的8大项目检测结果的极差均小于临界差值,具有可比性,检测结果差异无统计学意义。结论:极差分析法可用于检测原理相同的血细胞分析仪检测结果的比对。
Objective: Application of range analysis method to four Sysmex automated hematology analyzers in order to investigate the comparability. Methods : According to range analysis method,appropriate concentrations of specimens were chosen,tested on four automated hematology analyzer,the determination results were recorded. Results: RBC,HCT,MCH,MCHC test results of Sysmex automated hematology analyzer J-734-LJ were high,beyond the permitted range. After excluding the extreme value of J-734-L,range analysis test results of eight items of J-724-LJ,J-727-LJ,J-729-LJ were less than the critical difference,and the results were comparable,there was no significant difference among instruments. Conclusion: Range analysis method is suitable for detecting comparability among hematology analyzers with the same principle.
