Topic:

  • [pre-print, not peer-reviewed] Hanson et al. compared healthcare worker-collected nasopharyngeal swabs (NPS) to self-collected anterior nasal swabs (ANS) and saliva for diagnosis of SARS CoV-2 infection in adults accessing drive through testing (n=268). The positive percent agreement between NPS and ANS or saliva was 86.3% and 93.8%, respectively. Negative percent agreement was 99.6% for NPS vs. ANS and 97.8% for NPS vs. saliva. All participants had symptoms suggestive of COVID-19 infection.
