We propose a statistical procedure for long-term quality-control of laboratory instruments, including daily, day-to-day, and monthly evaluations. The procedure is based on the unique and unequivocal interpretation of five results for control sera by calculation of a Reliability Index and further manipulations of this unitless parameter. This method, which we have tested during the past two years, allows for monitoring analytical performance and making comparisons with results of interlaboratory surveys. The monthly analytical variability, expressed as "total error," is an indicator of the clinical usefulness of analytical results.
我们提出了一种用于实验室仪器长期质量控制的统计程序，包括每日、逐日和每月评估。该程序基于通过计算可靠性指数以及对这个无量纲参数的进一步处理，对对照血清的五个结果进行独特且明确的解释。我们在过去两年中测试了这种方法，它能够监测分析性能并与实验室间调查结果进行比较。以“总误差”表示的每月分析变异性是分析结果临床实用性的一个指标。
