Abstract

It was the second-year trial of external quality assessment for immunoassay in Korea. We attempted two trials of external quality assessments in 1996. A total of 4 specimens were distributed in two trials. In first trial, specimens were distributed to 406 laboratories with a response of 212 laboratories (52.9%). In second trial, specimens were distributed to laboratories who participated in 1st trial and 10 newly joined laboratories in 1996. Among 222 laboratories, 201 laboratories (90.5%) participated in 2nd trial. Besides of using commercially available control material, we also used home-made pooled sera as one of control material. The results are summarized as follows. 1. Most of the member laboratories use EIA method more than RIA method. Member laboratories are adopting analysers using chemiluminescence method and these chemiluminescence analysers are increasing in its number. 2. Abbott IMx and AxSYM analysers are most widely used for immunoassay tests in member laboratories. Some of IMx analysers are replaced to AxSYM analysers. 3. Among member laboratories using same type of analysers showed large coefficient of variations in some of test items. 4. In evaluation of serum immunoglobulins, member laboratories are using automated analysers such as nephelometer or turbidimeter instead of RID plates -manual method- for fast and accurate result reports.
