I need clarifications on the preparation for the test because when I asked my neurologist about the preperation - he said nothing. Its like thyroid test that I could come in anytime of the day with no preparation. But, when I read the Gluten File, preparation should include eating gluten for weeks prior to the test. Or does this preperation refer to only the biopsy and not to the bloodwork?

I would appreciate clarification on this.....

Thank you.
