摘要:

当体外诊断试剂厂商仅按医药行业标准对某个定性检测项目声明了空白限(LoB)时,临床实验室应完成该项目检出限(LoD)的性能验证。文章对多个医学相关个行业标准中LoD、LoB的定义进行分析,并指出其在各文件中的异同。同时将定性项目中C50浓度、C95浓度与定量项目中LoD、LoB的相互联系进行归纳、整理。

关键词: 检出限, 空白限, 临界值

Abstract:

Clinical laboratories should complete the performance verification of the limit of detection(LoD) of qualitative test items,when the manufacturer of in vitro diagnostic reagents only declares the limit of blank(LoB) according to the standards of pharmaceutical institutions. The definitions of LoD and LoB in several medical related institution standards are analyzed,and the similarities and differences are pointed out. C50 concentration and C95 concentration in qualitative test items are correlated with LoB and LoD in quantitative test items.

Key words: Limit of detection, Limit of blank, Cut-off value
