Comparing analytical characteristics of the tests for viability of the virus, it can be observed that the rapid tests are indistinguishable from each other (p-value = 0.4533, McNemar’s test with Edwards continuity correction), but they differ significantly from RT-PCR (p-value = 2.546 × 10−6 for SGTI-flex COVID-19 Ag, p-value = 1.519 × 10−8 for Biocredit COVID-19 Ag, McNemar test with Edwards continuity correction). Here, RENBP is linked to COVID-19.
