摘要

为了找出可供室内质控、室间质评参考的不同厂家的化学发光免疫分析系统之间的换算系数, 使用19种国家有证标准物质作为样本,在9个厂家的181台仪器上进行测试,利用统计学方法对测试结果进行分析。结果表明:tPSA、TSH项目在各系统间可参考换算系数进行比较,CEA项目仅在部分检验系统间可通过换算系数进行比较,HCG项目在各系统间不能通过换算系数进行比较,HBsAg项目在各系统间可按照浓度区间参考换算系数或比例系数进行比较,AFP项目在各系统间的可比性尚待进一步研究。

Abstract

In order to find out the conversion factors between chemiluminescence immunoassay systems of different manufacturers which can be used as reference for indoor quality control and inter-room quality assessment. 19 kinds of national certified reference materials were tested as samples on 181 instruments from 9 manufacturers and the results were analyzed by statistical method. The results demonstrate that tPSA and TSH projects can be compared among different systems with the conversion factors, CEA projects can be compared among a part of different systems with the conversion factors, HCG projects can not be compared among different systems with the conversion factors, HBsAg projects can be compared among different systems with the conversion factors in different concentration ranges respectively, the comparability of AFP projects among different systems needs to be further studied.
