Specificity assessment of the RT-LAMP assays for SARS-CoV-2 RNA detection using primer sets ORF1ab, E, N5, and N15. A panel of 13 purified RNA isolates of related viruses obtained from infected patients are included: Coronavirus NL63, Coronavirus OC43, Bocavirus, Rinovirus, Metapneumovirus, Respiratory Syncytial Virus A, Respiratory Syncytial Virus B, Enterovirus, Parainfluenzae 1, Influenza H1N1, Influenza A H3, Influenza A H1, and Influenza B. One sample contained RNA from two viruses (Influenza B + Coronavirus OC43); other sample contained RNA from three viruses (Influenza A H1 + Coronavirus OC43 + Adenovirus).
