We read with interest the recent paper from Fowler et al. on the use of a reverse transcriptase loop mediated isothermal amplification (RT-LAMP) assay for rapid detection of SARS-CoV-2 infection1 and the subsequent recommendation of its suitability for asymptomatic staff testing.2 Lateral flow device (LFD) antigen tests have also been proposed as rapid point-of-care diagnostics for SARS-CoV-2 infection and have the advantage over the RT-LAMP assay in that they can be self-delivered by healthcare workers at home with immediate results.
