I caught Kozak in an out an out lie yesterday on a different thread. He said that PCr are always positive and you always have the disease. He hasn’t been a very good doctor learning that dead particle from months ago that are not infective can turn a PCR positive. Of course the wimp never answered. He is still under his bed
I don’t know much about antigen tests. I assume they reliably show the presence or previous presence of some bodily invader.
No doubt they could be unreliable in the COVID 19 case. Is that correct?
