Abstract

This is the report of fourth-year trial of external quality assessment for immunoassay in Korea. We attempted one trials of external quality assessments in 1998. A total of 7 specimens were distributed with a response of 225 laboratories (79.5%). We used home-made pooled sera as the control material for all the immunoassays. The results are summarized as follows. 1. Laboratories participating in external quality control program of immunoassay increased in its number compared to previous years. 2. Abbott AxSYM analyser is most widely used for immunoassay tests. Use of chemiluminescence analyser, such as ACS 180 of Chiron Corp., Elecsys of Roche Corp. are increasing in similar numbers in some of test items. 3. Among member laboratories using same type of analysers showed large coefficient of variations in some of test items. We suspect that some laboratories may fail to analyse high value specimens using dilution method. 4. In evaluation of serum immunoglobulines, member laboratories are using automated analysers such as nephelometer or turbidimeter instead of RID plates (manual methods) for fast and accurate result reports.
