Test before gathering.
OK, but here’s a concern which my wife pointed out and which I now share…
False negatives were 5% to 10% on the BTNX rapid tests heavily distributed in 
; that was before Omicron. A single test done by an unpracticed hand on a virus with 4 nucleocapsid mutations (see BTNX’s statement) and we get what? Would 20% be an unreasonably high estimate for false negatives?
Would we be attending an indoor gathering with the (as of yesterday in Ontario, maximum) 10 people were it not for the test?
The Science Advisory Table advice on the tests was for a sequence of 5 used over the self-isolation period of individuals who had been in contact with a COVID case and were therefore more likely to test positive and unlikely to be exposed for the testing period.
It seems to us that people may use the tests as a green light to engage in riskier behaviours.
That might make things worse in the end…
