Mark you have made an incorrect assumption.

The info re the filter paper test came from a friend of mine who is a chemist. This was not a challenge but a simple statement of fact in the face of a lack of evidence based denial.

I spoke of the actuality of my circumstance, not research.

I am not a cyberchondriac, nor did the neuro ever infer anything like this, but rather booked the necessary tests that may add info for diagnosis.

Feel free to ask for clarification.
