Another possibility is the type of testing that is done.
I wish I could find the reference, but a month or more ago I read that some tests (< 3 days to result ?) only detect the presence of covid-19 bugs, not whether they are dead or alive (forgive the backyard science). If the sample is cultured for longer you eliminate these false positives.
