Comparison of the BD Directigen Flu A+B Kit and the Abbott TestPack RSV With a Multiplex RT-PCR ELISA for Rapid Detection of Influenza Viruses and Respiratory Syncytial Virus

Clin Microbiol Infect. 2005 Oct;11(10):848-50. doi: 10.1111/j.1469-0691.2005.01223.x.


The Directigen Flu A+B enzyme immunoassay and the Abbott TestPack RSV enzyme immunoassay were each compared with a multiplex RT-PCR ELISA by testing 635 nasopharyngeal aspirates collected from children aged < 16 years who had been hospitalised with acute respiratory tract infection during the epidemic season 2002-2003. In this study, the sensitivity of the Directigen Flu A+B assay was unacceptably low (29.3% and 10.0%, respectively) for the detection of influenza A and B viruses. The sensitivity of the Abbott TestPack RSV assay (77.4%) was acceptable and in agreement with the multiplex RT-PCR ELISA.
