Doesn't matter what I think. See what Celiac experts think:
"Why don’t you recognize tests (stool tests or otherwise) for non-celiac gluten sensitivity that are currently available through companies like Enterolab or Cyrex?
We only embrace tests that have endured rigorous scientific evaluations. So far, these tests have received no evidence-based support.
Enterolab has never successfully published anything on the accuracy of stool tests (nor have any other stool test manufacturers, to our knowledge) making it difficult to confirm the research results. Because of this, we must make our decisions based on what has been published; Harvard, UCSD, and the American College of Gastroenterology all agree that stool tests are simply not sensitive or specific enough methods in screening for celiac disease.
We can say therefore with confidence that the test currently being used by these labs is not good enough. In fact, while it is true that about 40% of people with proven gluten sensitivity have elevated AGA-IgG, it is also true that about 15-25% of the healthy individuals who have absolutely nothing wrong also have elevated AGA-IgG. Hence, about 60% of gluten sensitive people do not have elevated AGA-IgG (making the test not sensitive enough); and about 20% of normal, non-gluten sensitive people have elevated AGA-IgG for no apparent reason (making the test not specific enough).
