Swabbing for respiratory viral infections in older patients: a comparison of rayon and nylon flocked swabs	2010-09-18		.txt	text/plain	3364	185	55	The purpose of this study was to compare the sampling efficacy of rayon swabs and nylon flocked swabs, and of oropharyngeal and nasopharyngeal specimens for the detection of respiratory viruses in elderly patients. Regardless of the sampling site, a calculated 4.8 times higher viral load (95% confidence interval [CI] 1.3–17, p = 0.017) was obtained using the nylon flocked swabs as compared to the rayon swabs. Samples for the diagnosis of a respiratory viral infection can be obtained by swabbing the oropharynx, the nasal cavity, the nasopharynx or alternatively, by nasopharyngeal aspiration (NPA) or nasopharyngeal washings (NPW). The aim of this study was to compare the respective efficacies of rayon swabs and nylon flocked swabs in providing material for direct respiratory virus detection by real-time PCR in adults above 60 years of age. Using monoplex (RSV and human metapneumovirus) or multiplex (influenza A/B, adenovirus/internal control and parainfluenza virus 1-4) PCR methods, the specimens were examined for, in total, nine different respiratory viruses (Table 2) .	./cache/cord-349562-ivu632j2.txt	./txt/cord-349562-ivu632j2.txt
