Yes. I get that, that's why I said you need to use RNA tests for virus presence to enable containment, which is why I don't get MfA's concerns about antibodies confusing containment.
But additional to that, no test method is proving to be that accurate yet, so no matter how you test, you can't completely rule out someone being or having been infected.
