Thank for pulling out that false positive statistic. It is incredibly irritating when an article, even a press release type one like this, makes it a point to give an exact number for the true positive / false negative rate and then fails to answer the obvious other half of the question. It made me sneer "oh yeah? Well, a magic 8 ball that only ever says 'yes you have covid you're gonna die' would catch that remaining 1.5%; why aren't you doing that?"

But as usual, the fault is in the summary, not the research.

Based on the title, my first question was "If they are asymptomatic why are they coughing?" I know there are many reasons you can cough, (acid reflux, allergies, etc) but this still seems that if its detectable its not 100% asymptomatic. Im splitting hairs(possibley wrong?), yes, but to me asymptomatic means its completely passive

The 17% false positive rate could be a large problem here depending on the prevalence of asymptomatic infection.
