Rapid diagnosis of respiratory syncytial virus infection by using Pernasal swabs.

摘要

The sensitivity and specificity of direct immunofluorescence microscopy performed on Pernasal swab specimens and compared with those of nasopharyngeal aspirates were 93 and 99%, respectively. Posterior nasopharyngeal swabs applied immediately to microscope slides allow a rapid and simple screening procedure for the diagnosis of acute respiratory syncytial virus infections.
