enished due to insufficient production capacity or lack of international transport. Therefore, increasing daily test capacities for RT-qPCR–based diagnostics for SARS-CoV-2 RNA detection is currently limited. To accelerate and optimize such diagnostics, new scalable methods for RNA isolation and the detection of viral genomes are needed. An alternative to RT-qPCR is reverse transcription loop-mediated isothermal amplification (RT-LAMP) (5–7). RT-LA
