Abstract
A commercially available direct immunofluorescence (IF) test using a reagent consisting of a pool of two monoclonal antibodies against selected surface and internal proteins of respiratory syncytial virus (RSV) was evaluated in comparison with the indirect IF technique using a commercial bovine anti-RSV hyperimmune serum for the rapid detection of RSV in nasopharyngeal aspirates from 228 hospitalized children. Overall agreement between the two IF methods was 95%. The direct IF test was quicker to perform and easier to interpret than the indirect IF test.
