Lab Question

Hello! I have hashimoto's and asked my doctor to check labs for celiac. My ttg iga and ttg igg both cameback positive at 39 and 37, greater than 10 is positive. I'm going for an endoscopy in two weeks. I've heard that having an autoimmune thyroid condition could maybe cause a false positive lab. I'm just wondering what your labs were and if your biopsy ended up being positive or not. Thank you so much!

I don't know if I've seen a study that examined % of the false positives from other AI diseases.

Bottom line, lots of people with Hashis are Celiac. That's what the endoscopy and gluten-free trial are for.

Perhaps you can search PubMed, etc.and you can find a study or article?

      High blood test numbers - with scales. Any advice?

      By Scott Adams · Posted

      I agree with @RMJ, you have multiple positive tests so celiac disease is likely.  This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease.

      Newly gluten free… withdrawal?

      By trents · Posted

      One small study found that 50% of celiacs react to the dairy protein "casein" like they do to gluten. It is also common for celiacs to be lactose (the sugar in milk) intolerant, though that often disappears in time as the villi heal. About 10% of celiacs react to the oat protein "avenin" like they do gluten.

      Newly gluten free… withdrawal?

      By K6315 · Posted

      Thank you so much Trents (Scott?)! I have started working with a dietitian and did a deep research dive as soon as I got the diagnosis. I am aware of what you mentioned in the first two paragraphs, and was not aware of anything in the third, so I am grateful for that information, and will talk to the dietitian about that. I think I was most interested in the withdrawal process - it gives me hope that, although I have felt unwell recently, I just need to be patient (not a strong suit). I have printed the article you sent and will look at it more closely. Thanks again!

      By trents · Posted

      Welcome to the forum, @K6315! Gluten withdrawal typically lasts for a period of a few weeks. But there is a real learning curve involved in actually attaining to a gluten free dietary state. Much more is involved than just cutting out major sources of gluten such as bread and pasta. It's all the places that gluten is hidden in the food supply that is difficult to ferret out, like soy sauce and canned tomato soup, canned chili and canned pork n' beans, some "lite" pancake syrups, potato salad, flavorings, etc., etc. Gluten-containing grain products are hidden through alternate terminology and found in places you would never expect.  There is also "cross contamination" where naturally gluten free foods come into contact with gluten-containing grains during farming, transportation, storage and manufacturing processes. Then there is the issue of "cross reactivity" whereby you may be having gluten-like reaction to food proteins whose structure is similar to gluten. Chief among these are dairy, oats (even gluten-free oats), soy, corn and eggs. I am including this article that you might find helpful:
