They have 10 minute 99.5%+ accurate PCR tests? When did that happen?
I just want to interject with my anecdotal input. My father had fever last week, took two covid tests at the beginning of the week, one rapid and one non-rapid but same day. Both negative. Fever was persistent, so he retested Friday. Covid positive.
Obviously he could be in the statistical minority, or his fever was unrelated (highly unlikely), but the one story I know of someone who took the test gave a false negative IMO. (Yes, he seems to be fine, thanks for asking.)
