I recognize youve heard things like “50% sensitivity”

In light of your comments it’s clear there are key pieces youve missed

Sensitivity nears 100% to catch potential superspreaders and others currently transmitting, for example.

See https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)00425-6/fulltext

50% sensitivity is vs PCR. But as CDC (and hopefully you) know, PCR remains pos long after isolation & contagiousness end

Rapid Ag tests don’t stay positive past the infectious stage.

50% isn’t a lack of sensitivity of Ag... it’s a lack of specificity of PCR for infectiousness

And importantly, public health screening w rapid tests should not detect people after they have been infectious. Simply, when you say 50% sensitivity, you’re comparing apples and oranges.

One, a medical diagnostic. The other, a public health tool to answer “Am I infectious now”
