The Comparative Analysis on the Results among the Hematology Analyzers by Range Analysis Method

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.
