Is there any information available on the false positive rate for NaNose's COVID-19 detection? I've yet to see any. Even a low false postive rate could make it near useless for many purposes when the COVID-19 infection rate is low: https://en.wikipedia.org/wiki/Base_rate_fallacy. An airline, for example, couldn't use the system without other tests if most people pinged aren't actually infected.
