【摘要】 文献中有多项方法检出限评估标准,如何正确理解和运用这些标准得到可比较的参数对基层实验室具有指导意义。对目前国内外方法检出限评估方法标准进行了系统总结和梳理,介绍了不同方法的特点、适用范围和注意事项。利用实验室实例和文献数据,比较了三种代表性方法计算结果。基于科学性和可操作性的原则,针对不同需求,提出了检出限评估改进建议及实施方案。更多还原

【Abstract】 Several evaluation standards of method detection limit(MDL)have been reported in literatures.It is important to understand and use correctly these standards so that it could obtain reliable parameters for guiding base laboratories.In this paper,the evaluation standards of MDL at home and aboard were systemic analyzed and summarized,and their features,application scope and key points were introduced.Comparison results of three typical evaluation standards were presented using real data sets from literatures and the author’s laboratory.The modified procedure for the evaluation of MDL was proposed for different laboratory requirements according to scientific and maneuverability principles.更多还原
