We describe a quality control (QC) log including its advantages over the more commonly used Levey-Jennings and Shewart graphic charts. It represents a practical system of analytic quality control for quantitative assays in clinical chemistry. It utilizes cumulative sum (CUSUM) techniques and comparison of means to monitor acute and chronic analytic drift, respectively. Clinically useful limits (CUL) criteria for QC decisions are used. An algorithm to facilitate the description of, training for, and use of, the QC log system is provided.
我们描述了一种质量控制（QC）日志，包括其相对于更常用的Levey-Jennings和Shewart图表的优势。它代表了临床化学定量分析中一种实用的分析质量控制体系。它分别利用累积和（CUSUM）技术和均值比较来监测急性和慢性分析漂移。使用了用于质量控制决策的临床有用限度（CUL）标准。提供了一种便于描述、培训和使用质量控制日志系统的算法。
