Annual Report on External Quality Assessment of Immunoassay Subcommittee in Korea (2003) / 임상검사와정도관리

ABSTRACT

Two trials of external quality assessment were performed in 2003. Thirteen test items of immunoassay with ten control materials were surveyed. The response rate of external quality assessment for Immunoassay Subcommittee were 93.8% and 92.8%. Ten control materials were consisted of 8 home-made pooled sera and 2 commercial control sera. The results are summarized as follows. 1. Laboratories participating in external quality control program of immunoassay were 259 laboratories and the response rate were 93.8% and 92.8% in 2003. 2. Chemiluminiscence immunoassay autoanalyzer was now widely introduced comparing to previous years and now it is the most popular analyzer in the field of immunoassay testing. 3. Still some test items show big variations of the test results of the same control material according to autoanalyzer. Generally the quality of the participating laboratories seems to be thought being improved. And in the following years, new planning of the statistic analysis and some standardization protocols could be introduced.
