Abstract

In good laboratory practice (GLP), analytical method validation prior to toxicity testing is important in terms of concentration setting and sample preparation. The testing agency performed validation of the two requested test substances using high-performance liquid chromatography (HPLC), and as a result, the analysis satisfied the criteria for specificity, system suitability, linearity, intra-day reproducibility, homogeneity, stability, concentration analysis, and quality control. The method was established and validated. However, the content of standard substances in the test report of the requesting institution was found to be 1.34 and 1.17 times higher than the results of the testing institution, confirming that deriving results through validation of analysis methods suitable for GLP is important in terms of securing reliability and stability.

비임상시험관리기준에서 독성시험 전 분석법 밸리데이션은 농도 설정 및 시료 제조 측면에서 중요하다. 시험기관에서는 의뢰받은 시험물질 2종에 대한 밸리데이션을 고성능액체크로마토그래피를 이용하여 수행한 결과 특이성, 시스템 적합성, 직선성, 일내 재현성, 균질성, 안정성, 농도분석, 품질관리를 판정 기준에 만족하는 분석방법을 확립 및 검증하였다. 하지만 의뢰기관의 시험성적서상 표준물질 함량은 시험기관의 결과보다 1.34배, 1.17배 높은 결과로 나타나 비임상시험관리기준에 적합한 분석법 밸리데이션을 통한 결과 도출이 신뢰성과 안정성 확보 측면에서 중요함을 확인하였다.
