不同分析系统电解质检测结果比对分析

Comparison analysis between different analysis systems for the detection of electrolytes

目的分析德国罗氏公司Cobas8000型全自动生化分析仪(简称Cobas8000分析仪)和日本奥林巴斯公司AU640型全自动生化分析仪(简称AU640分析仪)K^+、Na^+、Cl^-检测结果的可比性。方法参照美国临床实验室标准化委员会EP9-A2文件,采用两套分析系统对新鲜血清标本K^+、Na^+、Cl^-进行检测,评价AU640分析仪检测结果的精密度,计算两套分析系统检测结果的相关系数。结果 AU640分析仪K^+、Na^+、Cl^-检测结果精密度较高,批内、批间变异系数均小于2%;两套分析系统K^+、Na^+、Cl^-检测结果的相关系数均大于0.975。结论 Cobas8000分析仪和AU640分析仪K^+、Na^+、Cl^-检测结果一致性较高,具有良好的可比性,均能为临床提供准确、可靠的检测结果。

Objective To investigate the comparability of K ^＋ ,Na^＋ and Cl^- measurement between Cobas8000 analyzer and AU640 analyzer .Methods According to the EP9‐A2 document of the National Committee for Clinical Laboratory Standards ,the precision of AU640 analyzer for the detection of K ^＋ ,Na^＋ and Cl^- was evaluated ,and the correlation between the detected results of the two analyzers were also analyzed .Results AU640 analyzer were with high precision for the detection of K ^＋ ,Na^＋ and Cl^- ,in‐tra‐assay and inter‐assay coefficient of variation of which were both less than 2% .The correlation coefficients of the two analyzers were higher than 0 .975 .Conclusion Cobas8000 analyzer and AU640 analyzer might be with fine comparability for the detection of K^＋ 、Na^＋ and Cl^- ,both of which could provide accurate detected results .
