Abstract

A premarket trial of the Becton Dickinson Directigen respiratory syncytial virus membrane-based enzyme immunoassay compared the test with virus isolation for the detection of respiratory syncytial virus in 583 nasopharyngeal aspirates. After modification, the Directigen test showed a sensitivity of 83% and a specificity of 90%. It offers the potential for an efficient bedside test--without the need for any equipment--for the diagnosis of respiratory syncytial virus infection and requires only a 0.25-ml sample volume. However, for optimum reliability, freezing-thawing of samples and access to a confirmatory test were shown to be necessary.

摘要

一项针对贝克顿·迪金森公司基于呼吸道合胞病毒膜的酶免疫测定法的上市前试验,将该检测方法与病毒分离法进行了比较,以检测583份鼻咽抽吸物中的呼吸道合胞病毒。经过改进后,迪瑞直检法显示出83%的灵敏度和90%的特异性。它具有进行高效床边检测的潜力——无需任何设备——用于诊断呼吸道合胞病毒感染,且仅需0.25毫升样本量。然而,为了获得最佳可靠性,样本的冻融处理以及进行确认性检测被证明是必要的。
