GBS Testing

Hi Gene
I am living in the bay area (norcal). I really appreciate your input! My family thinks the neurologist can’t be wrong, but I just don’t understand how he can effectively rule out GBS with 100% certainty unless he gives me that test you are talking about. I would love a second opinion but am not sure if my insurance will cover a visit to another neuro. I was thinking about visiting the Stanford Hospital’s dept of Neurology. They seem to have a clinic where they do all the tests.
