A regional quality control program was established using simulated clinical specimens introduced into the routine workload of participating laboratories in such a way that they were not detected as quality control specimens. Comparison of performance between these specimens and lyophilized cultures showed that additional information was obtainable with the former. In particular, it was observed that common pathogens such as Escherichia coli are poorly identified in clinical material. The examination of urines was inferior to examination of other types of specimens. The implications of these findings for the practice of diagnostic bacteriology are discussed.
通过将模拟临床标本引入参与实验室的日常工作量中，建立了一个区域质量控制程序，其方式是使这些标本不被检测为质量控制标本。这些标本与冻干培养物之间的性能比较表明，前者可获得更多信息。特别是，观察到临床材料中常见病原体如大肠杆菌的鉴定效果不佳。尿液检查不如其他类型标本的检查。讨论了这些发现对诊断细菌学实践的影响。
