【摘要】 目的配合１９９７年全国碘缺乏病监测工作，更好的完成新生儿脐带血ＴＳＨ水平测定，对全国省级实验室进行外部质量评定。方法分为ＥＬＩＳＡ、ＩＲＭＡ两种测定方法，２７个实验室中采用ＥＬＩＳＡ方法的有８个，采用ＩＲＭＡ方法的有１９个，评价指标为准确度和可比性。结果测定结果落在参考值范围内的省份，ＩＲＭＡ方法高、低浓度样品各有１６个、１４个，ＥＬＩＳＡ方法高、低浓度样品各有７个、５个；相对误差＜１０％的省份，ＩＲＭＡ方法高、低浓度样品分别为１５个、１３个，ＥＬＩＳＡ方法高、低浓度样品分别为５个、４个；并且多数省份的结果之间呈现较好的可比性。结论新生儿脐血ＴＳＨ水平测定质量还存在一定问题，我们应尽快建立统一的测定方法，加强技术培训和质量管理工作。更多还原

【Abstract】 Objective To cooperate 1997 China IDD survei llance and complete neonatal TSH level assay better,external quality control evaluation for provincial laboratories was made.Methods ELISA and IRMA methods were used.8 of 27 laboratories used ELISA and 19 of 27 used IRMA.Results The laboratories used IRMA that their measuring results were in the reference range were 14 and 16 for QC A and QC B.The laboratories used ELISA were 5 and 7.The laboratories used IRMA that their relative errors were <10% were 13 and 15 for QC A and QC B.The laboratories used ELISA were 4 and 5.Moreover,the results of most laboratories were comparable.Conclusions The assay quality of neonatal TSH level still has some problems.So we should establish unified assay method and reinforce skill training and quality management.更多还原
