Two simple methods of using sophisticated statistical techniques to analyse intralaboratory quality control data are described. One method uses a plastic grid to assess the cumulative sum (cusum) graph. An equivalent procedure, which may be carried out by a laboratory computer, gives automated on-line quality control of the Coulter S blood counter. The possible development of simple apparatus to carry out the same function is discussed.
本文描述了两种运用复杂统计技术分析实验室内质量控制数据的简单方法。一种方法是使用塑料网格来评估累积和(cusum)图。另一种等效程序可由实验室计算机执行,实现库尔特S型血液计数器的自动化在线质量控制。文中还讨论了开发执行相同功能的简单仪器的可能性。
