Diagnostic Accuracy of the Panbio SARS-CoV-2 Antigen Rapid Test Compared with Rt-Pcr Testing of Nasopharyngeal Samples in the Pediatric Population.

We conducted a multicenter clinical validity study of the Panbio COVID-19 Antigen Rapid Test of nasopharyngeal samples in pediatric patients with COVID-19 compatible symptoms of ≤5 days of evolution. Our study showed limited accuracy in nasopharyngeal antigen testing: overall sensitivity was 45.4%, and 99.8% of specificity, positive-predictive value was 92.5%.
