Preparation and Application of ISE Reagent Kit for Beckman CX Series Automatic Chemical Analyzer

摘要:目的: 研制贝克曼CX系列全自动生化分析仪电解质配套试剂盒。方法 评价自配电解质试剂盒的主要性能指标:准确度、精密度、线性范围、稳定性和相关性,并与原装试剂进行临床标本测定结果比较。结果 自配试剂盒测定定值血清Na+、K+、Cl平均相对偏差均小于2%;批内精密度、批间精密度较好,变异系数(%)均小于2%;与原装试剂测定结果高度正相关,相关系数〖WTBX〗r 均大于099。结论 自配试剂完全可以取代进口试剂进行临床应用。Abstract: Objective: To develop ISE(ion selective electrode) reagent for Beckman CX series automatic chemistry analyzer. Methods : Validation the main performances of selfmade reagent, including accuracy, precision, linear range, stability, and relevance, and carried clinical comparison test with the original reagent kit. Results : The main performances of selfmade reagent achieved the experimental anticipated request. As analyzing the valued serum, the average relative deviations of Na+,K+,Clwere less than 2%; withinrun precision and betweenrun precision were good,coefficient of variations were less than 2%; the selfmade reagent was highly correlated with the original reagent kit,correlation coefficient was greater than 099 Conclusion : Selfmade reagent could substitute the original reagent kit for clinical laboratory.
