I saw a video where some people took the swabs used for the tests, and they left odd fibers, very straight and short, not curly like you would expect from a swab, imbedded in a piece of raw chicken? they used as the surrogate for a mucus membrane. The same people also showed static electricity causing what looked like regular cottom fibers, to "dance", and they thought it meant they were alive, so who knows if the odd, straight fiber thing is either real or significant, but I wouldn't put it past all involved to have the tests doing something to everyone.
