Nonserologic test for COVID-19: How to manage?

ABSTRACT:

Background

Diagnosis of Severe Acute Respiratory Coranavirus-2 (SARS-CoV-2) infection is currently based on real-time PCR (RT-PCR) performed on either nasopharyngeal (NPS) or oropharyngeal (OPS) swabs; saliva specimen collection can be used, too. Diagnostic accuracy of these procedures is suboptimal, and some procedural mistakes may account for it.

Methods and results

The video shows how to properly collect secretions from the upper airways for nonserologic diagnosis of COVID-19 by nasopharyngeal swab (NPS), oropharyngeal swab (OPS), and deep saliva collection after throat-cleaning maneuver, all performed under videoendoscopic view by a trained ENT examiner.

Conclusions

We recommend to perform NPS after elevation of the tip of the nose in order to reduce the risk of c
