Abstract

Background: Broad diagnostics of respiratory infection by molecular assays has not yet won acceptance due to technical difficulties and high costs.

Objectives: To evaluate clinical applicability of multiplex real-time PCR.

Study design: An assay targeting influenza virus A (IfA) and B (IfB), parainfluenza 1-3 (PIV), human metapneumovirus (MPV), respiratory syncytial virus (RSV), rhinovirus (RV), enterovirus (EV), adenovirus (AdV), human coronaviruses (229E, OC43, NL63), M. pneumoniae and Ch. pneumoniae was developed and run daily on consecutive clinical nasopharyngeal swab samples.

Results: An etiology was identified in 48% of the 954 samples, with IfA in 25%, RV in 20%, MPV in 10% and M. pneumoniae in 10% of the positive. By a rational procedure costs could be reduced and the customer price set relatively low (euro33 per sample).

Conclusion: Streamlined testing and cost limitation is achievable and probably critical for implementation of a broad molecular diagnostics of respiratory infections.
