血细胞分析仪比对试验的应用探讨

Study on the Application of Hematology Analyzer Comparative Test

目的通过比对实验，了解本实验室不同品牌、型号血细胞分析仪检测结果的准确性和一致性，探讨有效检测范围对一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MEK-8222K与HMX检测结果间一致性好，偏差在允许误差内。与HMX比较，SF-3000的HCT、WBC测定有效检测范围不合质控要求。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 Through comparative test, understand the accuracy and conformity of outcomes of different label and style hematology analyzers and explore the evaluation of effective testing range to hematology analyzer. Methods Select one well-functioned hematology analyzer as the referring comparative analyzer and apply fresh anticoagulation whole blood and whole blood quality control product simultaneously on several hematology analyzers to test and compare the precision, relative deviation of high/medium/low testing outcomes and effective testing range of every analyzer and the referring comparative analyzer. Results Testing outcomes of MEK-8222K and HMX had good conformity and deviation was in the allowed error. Compared with HMX, HCT, WBC measuring effective testing range of SF-3000 cannot qualify for quality control. Conclusion Effective testing range combined with accuracy evaluation, the accuracy and conformity of hematology analyzer testing outcomes can be more effective.
