在这项研究中，Oxoid Aura图像抗生素敏感性测试系统，作为一个独立的设备，进行了比较，手动区域测量和使用的模板，用于确定敏感性。当区域之间的差异在3 mm以内时，观察到使用Aura图像系统测量的区域直径和手动测量的区域的总体相关系数为0.99; 5.4%的区域显示手动和自动测量之间的区域直径差异>3 mm。使用模板方法进行解释获得的结果不如区域测量可靠，头孢呋辛和氨苄西林对肠杆菌科和不动杆菌属进行了试验。当连接到实验室患者数据库时，条形码和光盘识别设施避免了与手动数据输入相关的错误。
In this study the Oxoid Aura image antibiotic sensitivity test system, used as a stand-alone device, was compared with manual zone measurement and use of a template, for the determination of sensitivities. An overall correlation coefficient of 0.99 was observed for zone diameters measured using the Aura image system and zones measured manually, when the differences between zones were within 3 mm; 5.4% of zones showed a difference in zone diameter between manual and automated measurement of >3 mm. The results obtained using the template method for interpretation were less reliable than zone measurement, with cefuroxime and ampicillin tested against Enterobacteriaceae and Acinetobacter spp. When linked to a laboratory patient database, the bar code and disc identification facilities avoided errors that were associated with manual data entry.
