Abstract
Specimen taken from the surface of the respiratory mucosa is an established procedure used to evaluate patients with suspected upper respiratory infection. Nasopharyngeal (NP) swabs are regarded as highest-yield sample to detect respiratory viruses (1). This method gained further attention during coronavirus infectious disease 2019 (COVID-19), one of the deadliest pandemics in history. The procedure involves the insertion of a long flexible swab through the nostril along the floor of the nasal cavity towards the nasopharynx. NP swabs need to be performed by trained professionals and fortunately adverse events are rare.
