Rapid detection of respiratory syncytial virus in nasopharyngeal specimens obtained with the Rhinoprobe scraper

Abstract

We compared the Rhinoprobe scraping technique for collection of superficial nasal mucosa epithelial cells and rapid detection of respiratory syncytial virus by immunofluorescence with paired, swab-collected specimens for virus culture from 1,257 infants and children with acute respiratory infections. Compared with viral culture as the reference test, the sensitivity, specificity, and accuracy of the immunofluorescence test were 83.6, 93.6, and 91.3%, respectively. We found the Rhinoprobe method safe, easy to use, and helpful in obtaining large quantities of epithelial cells for detection of respiratory syncytial virus and other respiratory viruses.
