" Don’t depend on an unapproved diagnostic tool, like the opinion of a naturopathic doctor or the popular Cyrex Array tests recommended by Dr. Perlmutter. Why not? Just ask Dr. Alessio Fasano: When you develop a new drug or test, there are these rules created by the American Medical Association that [we are asked] to obey. We don’t take this lightly since we are dealing with health and therefore the well-being of human beings, so we want to make sure that we do this right. If somebody will develop a new tool, a new biomarker, a new test—first and foremost, it needs to be validated. The tests that are offered for gluten sensitivity didn’t go through this vigorous validation process. "
