Reliability Of Anti-tissue Transglutaminase

I have read on this board that several people have stated that the anti-tissue transglutaminase was very specific for Celiac. According to this article: Open Original Shared Link it states that low positives are also found in Chron's disease. I know that some people were diagnosed by blood test alone, and I am just wondering how they know it isn't chron's disease they have? I'm still trying to fugure mine out!

tTG is very specific for celiac and is more of an indicator of damage. I am a fan of the complete panel because the other tests they run detect a problem with gluten in the body and are all needed for their piece of the puzzle. I was diagnosed by blood tests alone and had the full panel done. I also had a gene test which showed I carry one of the main celiac genes. In addition to that since Crohn's runs in my dads side of the family I had a small bowel series done(where you drink barium or whatever-the stuff that tastes like chalk) and that ruled Crohn's out.

      I'm not saying this is what you have, but your description reminds me of Morgellons, which are not very well understood. Here is a review from a reputable source. If it seems similar to your experience, you could raise this question with your Dr.  https://my.clevelandclinic.org/health/diseases/morgellons-disease

      Hi Trent, no dairy. Other than good quality butter. I have been lactose free for years. No corn, sugar, even seasonings and spices. I don't eat out. I cook my own food.

      @nancydrewandtheceliacclue, are you consuming dairy? Not sure if dairy is part of the carnivore diet.

      Hello Russ! Thank you so much for your reply.  I have not had an antibody test done, ever, relating to gluten. Last year I had an allergy test done via blood draw (as my insurance wouldn't cover the skin test) but this was for pollen and grasses, not food. Even on the blood test I had extremely high levels of reactions to each allergen. Could this seasonal allergy inflammation be contributing to my celiac inflammation? I am so careful, there is no way I could ingest gluten. For example, couple of months ago I tried a cough drop that says it was gluten free. I checked ingredients, it seemed fine. But just taking one of those caused me to have nausea, vomiting, and the same extreme abdominal pain. Have you ever heard of anyone else having symptoms like mine after being diagnosed celiac and strictly gluten free? The last episode I had like this was yesterday, after I ate a certified gluten-free coconut macaroon with a little chocolate on it. I have eaten coconut and chocolate before with no issue,  so I didn't see how I could all of a sudden have such a strong response.

      The sensitivity of people with coeliac disease varies greatly between individuals. The generally accepted as safe limit for most people is 10 milligrams per day. This equates to a piece of bread the size of a small pea. Some people report that they are more sensitive than this, but others can very occasionally eat a normal gluten containing meal without reacting. I don't think that touching or throwing bread around would lead to you ingesting enough to cause a reaction. There are case reports of farmers with coeliac disease reacting to the dust from gluten-containing animal feed but they were inhaling large amounts of dust over a long period of time in barns. Perhaps you episodes are caused by a reaction to something other than gluten? Have you had your antibody levels checked to see whether you are still being exposed to gluten?
