Multicenter evaluation of BD Veritor System and RSV K-SeT for rapid detection of respiratory syncytial virus in a diagnostic laboratory setting

The recently introduced BD Veritor System RSV laboratory kit (Becton Dickinson, Sparks, MD, USA) with automatic reading was evaluated and compared with the RSV K-SeT (Coris BioConcept, Gembloux, Belgium) for the detection of respiratory syncytial virus (RSV) using 248 nasopharyngeal aspirates of children younger than 6years old with respiratory tract infection. Compared to reverse transcriptase polymerase chain reaction as gold standard, both tests had an identical sensitivity of 78.1% and a specificity of 96.8% and 95.8% for the BD Veritor System and RSV K-SeT, respectively. Both antigen tests can be used to reliably confirm RSV in young children. However, a negative result does not definitively exclude the presence of RSV.
