[quote=Anonymous]BMJ wiki on false positives. Even with a 99.9% test specificity (like for rapids), you still get a high percentage of your positives being false positives. For example, stick in a 44% test sensitivity (like for rapids in asymptomatic individuals) and a 99.9% test specificity, with a true positivity rate of 1%. You get 23% of your positives are false positives. https://www.bmj.com/content/373/bmj.n1411/rr [/quote]
