We recommend to perform NPS after elevation of the tip of the nose in order to reduce the risk of contamination from the nasal vestible, and to let it flow over the floor of the nasal cavity in parallel to the hard palate in order to reach the nasopharynx. Then the tip of the swab should be left in place for few seconds, and then rotated in order to achieve the largest absorption of nasopharyngeal secretions. Regards OPS, gentle anterior tongue depression should be used to avoid swab contamination from the oral cavity during collection of secretions from the posterior pharyngeal wall. These procedural tricks would enhance diagnostic reliability.
