Much as I have tried to find alternate tests that they will accept, my hospital insists that I take COVID PCR Nasal tests in advance of two upcoming out-patient procedures.

I've read many concerns about the swabs being used. Some can be called conspiracy theories. But many come from trained and qualified doctors and nurses.

These concerns range from the swabs being just in general dirty and contaminated, to being seeded with the Covid virus itself, to containing nanoparticles, to having been exposed to high concentrations of cancer-causing decontaminates.

So, is there anything I can do to mitigate or nullify any impact being done to my body via those sinus passages?

For example, immediately use a colloidal silver spray?
