title: Application of pooled monoclonal antibodies for 1-hr detection of respiratory syncytial virus antigen in clinical specimens.
abstract: A fluorescein isothiocyanate-conjugated pool of monoclonal antibodies (MoAb) to respiratory syncytial virus (RSV) was prospectively evaluated for its utility as a direct, 1-hr test for the diagnosis of RSV infection. Direct nasopharyngeal swab smears collected from 109 infants and children with acute respiratory illnesses were studied and compared with results obtained by indirect immunofluorescence using bovine polyclonal anti-RSV antibody on eluted cells derived from pooled nasopharyngeal and throat swab specimens (a 2.5-3 hr procedure), and culture. The MoAb-direct smear method was at least 86%-89% sensitive and 95%-100% specific compared with either of the other procedures. Additional prospective evaluations, as well as retrospective studies on a selected bank of slides stored from the preceding year, established that this MoAb could also be used with confidence in testing where direct smears are not employed.
