It may. I thought that the antigen tests really only work if taken during the viral outbreak. Once the body destroys the virus there is no need to produce antibodies, and thus no antigen available that would show up in the test. So iirc, the antigen test is fairly useless after several months past recovery.
Open to and appreciate any corrections.
“Open to and appreciate any corrections.”
A totally valid point.
I have no idea, but if currently poorly distinguishing, better tests would seem to be available to be developed.
