A simple statistical calculation was applied to 8 years of data on routine control sample and duplicate analyses from a laboratory quality control program. This provided standard deviations truly representative of this laboratory at no additional analytical expense, and accurate information on how they varied with concentrations. From these, the detection limit of the method, upper warning limits, and upper control limits for differences between duplicate analyses were calculated. These values were conveniently used for quality control in determinations of lead in blood and of mercury in urine.
对某实验室质量控制程序中8年的常规对照样品和重复分析数据进行了简单的统计计算。这在不增加额外分析费用的情况下提供了真正代表该实验室的标准偏差，以及关于它们如何随浓度变化的准确信息。据此计算出了该方法的检测限、上限警告限以及重复分析之间差异的上限控制限。这些值便于用于血液中铅和尿液中汞测定的质量控制。
