혈청 LDH 효소분석 검사의 표준화에 관한 연구

Abstract

Since the Korean Association of Quality Assurance for Clinical Laboratory was established in 1976, the numbers of the participating hospitals nowadays were increased from 40 to 450 or moer hospitals all over the country. In the early day the both intemal and extemal quality control programs were started at the same time, howerver, the extemal QC programs prevailed over the internal ones putting the cart before the horse. The accuracy and the precision of the data are not satisfying in spite of the 20 years experiences of quality control programs. All the daily data should be reprted after the validity is assured by the self-evaluation not by third party evaluation. It is regret that the CVs of enzymatic tests in extenal QC are exceeding 10% and there is no sign of diminishing CVs. One ofthe major reasons is that the types of anaytical instrurments and reagents are diverisified. Moreover, most of them are subject to the standards of the respective country of manufactuer. Accordingly, we can make a suggestion that the reagents and instruments should be imported or supplied meeting the established requirements for korean standafdization.
