Our study shows the clinical usefulness of tongue, nasal, or mid-turbinate samples collected by patients as compared with nasopharyngeal samples collected by health care workers for the diagnosis of Covid-19. Adoption of techniques for sampling by patients can reduce PPE use and provide a more comfortable patient experience. Our analysis was cross-sectional, performed in a single geographic region, and limited to single comparisons with the results of nasopharyngeal sampling, which is not a perfect standard test. Despite these limitations, we think that patient collection of samples for SARS-CoV-2 testing from sites other than the nasopharynx is a useful approach during the Covid-19 pandemic.
Swabs Collected by Patients or Health Care Workers for SARS-CoV-2 Testing
Aumenta la posibilidad de las autotomas de Pcr, ello unido a la estrategia de pcr por lotes (viajeros de una avión ó grupos de viajeros) podría ser muy interesante. El problema de esto ultimo puede ser la inhibición por dilución que creo que hay que estudiar más.
