May 5, 2020 · Pancoronavirus RT-PCR Assay. The pancoronavirus RT-PCR assay first analyzes the suspected clinical sample for all the coronaviruses. If a positive reaction is detected in the test, a second test is performed using gene sequencing to determine whether the coronavirus is SARS-CoV-2. Therefore, this assay can take up to 24 h to confirm COVID-19. Navaratnam, A. et al.
