Limit of detection of the LAMP assay was evaluated by using a nasopharyngeal (NP) swab sample infected with SARS-CoV-2 for which the viral load was quantified using digital droplet PCR (see Supplementary Methods). Twenty four replicates from a serial dilution containing 25-50 copies of SARS-CoV-2 which equates to 1X LOD (patient sample NP swab in VTM viral load confirmed by digital droplet PCR) per reaction were tested using dual-target RT-LAMP (Table 3) . The dual-target RT-LAMP test for SARS-CoV-2 developed in this study has comparable analytical sensitivity and specificity, limit of detection, precision, and achieved excellent agreement compared to the reference RT-PCR methods used internationally. ./cache/cord-343136-kftffes0.txt ./txt/cord-343136-kftffes0.txt
