Title: Sensitivity of nasopharyngeal swabs and saliva for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Cord-id: 36ijzvox Document date: 2020_6_25
ID: 36ijzvox
Snippet: We enrolled 91 consecutive in-patients with COVID-19 at six hospitals in Toronto, Canada, and tested one nasopharyngeal swab/saliva sample pair from each patient using real-time reverse transcriptase polymerase chain reaction for SARS-CoV-2. Sensitivity was 89% for nasopharyngeal swabs and 72% for saliva (p=0.02); difference in sensitivity was greatest for sample pairs collected later in illness.
