What are your symptoms? What has brought you to the point where you sought celiac disease testing?

Thanks so much. This is what I thought but really wanted a second opinion. I appreciate this. 

I have heard about numerous food sensitivity tests blood and the prick and how nothing is very reliable I think trial and error probably best bet.

As ShariW explained, soy itself doesn't contain gluten but most soy sauces sold in stores and used in restaurants contain wheat as an ingredient so they are not gluten free. As I understand it, there are two traditional ways of making soy sauce. One way contains wheat and one doesn't. The most popular one found out there in the wild does contain wheat, however. Kikkoman offers a line of gluten-free soy sauce and Teriyaki products that are often sold by grocery store chains like Safeway. There are food allergy/food sensitivity tests available and your physician can order them or give you a referral. They fall into two categories, the skin prick kind and the blood test kind. One you might look into is called the ALCAT test which might be the most helpful for foods. However, the reliability of these things is questionable. The results can be helpful as a place to start but the results often don't match up with real life experience. There are reasons for this and you might do well to research food sensitivity testing reliability on the Internet. 

The IGA TTG (aka, TTG-IGA) is the centerpiece of celiac disease blood antibody testing. A high value in this test indicates probable celiac disease, though there are other reasons (some other diseases, some medications and in some cases, even some non-gluten foods) that can cause it to be elevated. And it is not unusual at all for other celiac antibody tests to be normal when the TTG-IGA is high. Normally, when the TTG-IGA is elevated, the physician will order an upper GI with biopsy of the small bowel lining to check for the damage characteristic of celiac disease. The biopsy is then sent out for microscopic analysis. This is to confirm the results of the blood testing and is considered the gold standard diagnostic test. You should not begin a gluten free diet until the endoscopy/biopsy is complete. This is very important because otherwise the results will be invalidated.  This article on celiac disease blood antibody tests might be helpful to you while you are waiting for feedback from the physician:
