Yes, that’s fine. But what concentration is likely to be on the test swabs? And how much of it transfers to the mucosa or bloodstream?
it would be minor but as with radiation or many other poisons it can build up in the body over time - that’s what the nurse is saying...if you get swabbed every week for a long time it could build p.
Now....do I agree that the build up will be sufficient to cause problems... no not really, but some people are more susceptible.
