So, is it that 4 of the 10 were
JC antibody negative, BUT, had
JC viral in their blood? If so, wonder how the ab test doesn't catch this...
Guess this extra knowledge requires a degree in immunology, lol
I wonder further how frequent it is that people test positive for certain virus in blood but ab negative.
Again, I'm on a big learning curve here. So, if my thinking out loud if off because I'm misinterpreting the facts I apologize.
