Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infection in children. Rapid identification of RSV infections would allow for specific chemotherapy. We evaluated a means of rapid diagnosis, the Abbott enzyme immunoassay (EIA), by using 314 stored nasopharyngeal aspirates. RSV antigens were identified in 62 of 66 RSV culture-positive specimens. An additional 37 specimens from which RSV was not isolated were positive in the EIA. Of these, 29 were confirmed as truly positive by a blocking assay, for a total of 95 (66 + 29) positive specimens. The sensitivity of the EIA for total positive samples was 96% (91/95) versus 69% (66/95) for cell culture. The specificity of the EIA was 96% (211/219). In these stored specimens, Abbott EIA was superior to cell culture for the detection of RSV.
呼吸道合胞病毒(RSV)是儿童下呼吸道感染的主要病因。快速识别RSV感染将有助于进行特异性化疗。我们通过使用314份储存的鼻咽抽吸物评估了一种快速诊断方法,即雅培酶免疫测定法(EIA)。在66份RSV培养阳性标本中的62份中鉴定出了RSV抗原。另外37份未分离出RSV的标本在EIA中呈阳性。其中,29份通过阻断试验确认为真正阳性,总计95份(66 + 29)阳性标本。EIA对总阳性样本的敏感性为96%(91/95),而细胞培养为69%(66/95)。EIA的特异性为96%(211/219)。在这些储存的标本中,雅培EIA在检测RSV方面优于细胞培养。
