ABSTRACT
Without global mass vaccination, COVID-19 will continue to infect and cause serious illness, disproportionately in low- and middle-income countries. Point-of-care and home-based nucleic acid amplification tests (NAATs) are valuable tools to control COVID-19 transmission. Here we present a rapid isothermal NAAT for duplexed detection of SARS-CoV-2 and an MS2 bacteriophage internal control. This assay amplifies RNA in less than 15 minutes, utilizes a low temperature of 39°C, and has fluorescence or visual lateral flow readout. This positions our assay for use in low-cost paper-based nucleic acid diagnostic devices for ultrasensitive and reliable COVID-19 detection in POC or home-based settings. © 2021 MicroTAS 2021 - 25th International Conference on Miniaturized Systems for Chemistry and Life Sciences.
