摘要
目的评价本室几台血细胞分析检测结果的准确性和一致性,探讨有效检测范围对血细胞分析仪的评价。方法选择一台性能较好的血细胞分析仪作为参考比对仪器,采用新鲜抗凝全血及全血质控物同时在几台血细胞分析仪上检测,比较各仪器与参考比对仪器的精密度、高中低值检测结果的相对偏差和有效检测范围。结果CD-1700、CelltacF与KX-21N检测结果间一致性好,偏差在允许误差内。与KX-21N比较,CD-1600、Pentra120、Celltacα的HCT测定、CD-1600WBC测定及Pentra120RBC测定的有效检测范围不合质控要求,有效检测范围比相对偏差更能全面评价仪器性能。结论有效检测范围结合精密度评价血细胞分析仪检测结果的准确性和一致性更全面有效。
Objective To evaluate the veracity and consistency of the results obtained from several automated hematology analyzers by valid analysing range. Methods Anticoagulative peripheral blood and QC blood were determined by one automated hematology analyzer with best performance as reference analyzer and other ones respectively. The precisions and complete blood count results were compared with those among automated hematology analyzers by relative bias and valid analysing range. Results Compared with the results of KX-21N, the results by CD-1700 and Centac F showed excellent consistency, the results of HCT and RBC showed difference by Pentra 120, HCT showed difference by CD-1600 and Celltac α, respectively. Valid analysing range, compared with relative bias, was better effective in evaluation of hematology analyzer. Conclusions Valid analysing range joined with precision is of better effective in evaluation of hematology analyzer.
