Hi Shelly,

The most commonly ordered tests for celiac disease are:
anti-tTG and/or anti-endomysial
total IgA (this rules out IgA deficiency, which would affect the other results)

I think Prometheus lab includes antigliadin antibodies on their panel, although it is falling out of favor because the newer tests above are more specific to celiac disease. However, some still believe that antigliadin antibodies are important...so, hopefully they were included!

I have read that some people with Crohn's do respond to a gluten free diet, and others to a yeast free diet. Yeast sensitivity is the more common in Crohn's.

There are some studies and information in the following links that might provide some useful info. You will see a few references to Anti-Saccharomyces cerevisiae antibodies (ASCA).

IBS, IBD, Crohn's

Food Allergy & Leaky Gut Syndrome

Information on celiac disease diagnostics and much more can be found on other pages of The Gluten File....just scan down the right bar.

Hope this helps,

Cara

P.S. Those with autoimmune thyroid disease (looks like you might have it) have a higher risk of having celiac disease. In fact, some suspect the gluten sensitivity comes first, but goes unrecognized. There are some isolated reports of thyroid antibodies decreasing with a gluten free diet if begun soon enough.

After 18 months on gluten-free diet, the anti-thyroid antibodies titre decreased significantly, and we could discontinue thyroid substitutive therapy.

In a prospective study of 90 patients with celiac disease, we found that the prevalence of diabetes and thyroid-related serum antibodies was 11.1% and 14.4%, respectively. Like antiendomysium autoantibodies, these organ-specific antibodies seem to be gluten-dependent and tend to disappear during a gluten-free diet.
