Comparison of nasopharyngeal flocked swabs and aspirates for rapid diagnosis of respiratory viruses in children.
The quality of clinical specimens is a crucial determinant for virological diagnosis. ⋯ NPA remains the optimal specimen for diagnosis of respiratory infections by RT-PCR and DIF. However, collection of NPFS is easier to perform in an out-patient setting, was more acceptable to parents and less likely to generate aerosols than NPA engendering potentially less infection control hazard.
