PCR can’t amplify RNA that’s not on the swab, and you need ~300 copies to work reliably. The question is will there be adequate RNA in the nose if replication is inhibited in the nose. Not saying I have the answer, it’s a question.

My understanding of the protocol is that normally they only did a PCR if there was an antigen +. They also did PCR on everyone at the end. I'd expect all antigen+ to be PCR+. Do you think if the virus is replicating in the lungs but inhibited in the nose that this doesn't affect PCR performance?

My question when I saw that paper was how much of the effect is azelastine just interfering with the test? I.e. if we grant that azelastine inhibits, what if you get COVID and then squirt some up your nose, and then later swab your nose, will the inhibition make the test go negative?

Yeah this sounds awesome!
