Category: Article Summary
Topic: Testing and Treatment
- Compared to clinician-collected swabs, home-based self-collected swabs had a sensitivity of 80.0% (95% CI: 63–91%) and a specificity of 97.9% (95% CI: 94–99.5%). These results were based on a cohort of 185 symptomatic people who presented at drive-through clinics in Washington State who underwent both an unsupervised home self-collected swab and a clinician-collected nasopharyngeal swabs for diagnosis of SARS-CoV-2 infection by RT-PCR.
