A 40% false positive may be acceptable for purposes of quarantining, so long as the false negative rate is low and the percentage of healthy people being tested is relatively low. It'd be a bit like a bloom filter of quarantine. Can this person skip quarantine? Test says okay. Can this other person leave? Test says no, but that's not solid evidence that they have the disease.

Oh, well in that case, yeah, I agree, that's not very useful.
