What Do I Need To Eat Before celiac disease Blood Test?

Hi there

I am very sensitive to gluten and want to be tested for celiac disease.

I know that you need to eat a load of gluten before the tests, and eating wheat bread would be intolerable for so long - I would be laid out for the whole time!!!

I know that Spelt has less of an effect on me, and I would only be deeply uncomfortable for the period if I was eating Spelt bread. (And it would give me a few weeks to enjoy the wonderful Sourdough Spelt loaf that I used to love, even if I have to suffer for it...)

Is Spelt as good as standard wheat to eat before the test?

Thanks for any advice

Guy

Well, we're all different, but I'd have to guess that a lesser outward reaction could mean a lesser immune response. Thus it might make the test results even more unreliable than they already are, if you were to eat spelt instead of wheat.

However, if the blood test is like the biopsy in terms of how long you need to be eating gluten, you're looking at at least six weeks of misery. And if you've already been gluten-free for awhile, the reaction may be worse. IMHO, you already know you cannot eat wheat, and if other gluten grains also effect you, then whether or not it is Celiac doesn't seem to make much difference in terms of diet. But, if it helps you to stick with it, then by all means get tested. Just keep in mind that the test results may be negative for Celiac, even if you do have it. Especially since you've apparently been gluten-free. In addition, if you decide to go for the biopsy (which many doctors insist upon before giving a firm diagnosis of Celiac), you would have to intentionally damage your small intestine by ingesting gluten for a sufficient period of time. How long that is seems to vary from person to person, but the two weeks which doctors often suggest has been repeatedly shown to be inadequate. Six weeks is usually suggested here on the board, as a minimum.

not necessarily.

it really depends on which test. more than likely gliadin antibodies will be present in your blood as long as you are consuming gluten (whether wheat/rye/barley/spelt). there does, however, need to be sufficient intestinal damage to result in the breakdown of the endomysium (hence, endomysial antibodies) or TTG (tissue transglutaminase).

the intestine repairs itself very quickly; remember that the intestinal tissue (just like your skin) grows quickly and replaces itself by sloughing off older cells. this means that even with a week off of gluten, you will have much less endomysial protein or TTG in your blood to stimulate the production of antibodies. it is also why you need to be consistently consuming gluten if you intend on having an endoscopy.

Thanks RiceMan and gfb1

I have been looking into it today, and do not think I can go through the 1-2 months of agony!!!! I will just assume that I am coeliac and live accordingly. It can't do me any harm. It means that I won't get all my gluten free food free on the NHS (I am from the UK), but to be honest, I know what a couple of days is like on wheat, and cannot imagine a couple of months!!!

Guy - I couldn't agree more with what RiceGuy said about suffering for something you already know to be true. I'm happy to read you are going to forgo the test, because honestly what does it do for us? We eat gluten-free and are finally HAPPY and feel GREAT, then we have to torture ourselves and destroy our bodies, for a doctor to call us and say "oh, yep, you were right." Or even worse, they call and say the test shows a negative. But you were SO miserable leading up to the test, so you will go back to gluten-free anyway because that's the only time you feel great. I agree you will be happier just continuing to eat gluten-free knowing your own diagnosis.

If it was required to have a diagnosis in order to receive treatment that would be different - but since the only treatment is changing the foods you put into your body, receiving the diagnosis is just kind of.... pointless. NOW, if you had no or low symptoms (which some Celiac's do) while eating gluten, the test would be helpful since the symptoms are so mild it is hard to tell if the diet works.

Consider you have it, and consider you might pass it on as there can be family history of Celiac.

That's how I roll. B)

:D

Thanks for this, TiffLovesBread

BTW - what bread do you love and how to you make it? I made my first gluten-free (sourdough) bread today using Rice, Tapioca, Potato, Gram and Sorghum flours, with a brown rice flour starter and small amounts of Xanthan Gum, sugar, honey and live yoghurt. Tasted great, but heavy as a brick!!! Any idea how to make it lighter???

It might be possible to use baking powder, I use that, or you can try the artisan bread recipe where you keep the dough (gluten-free) on the kitchen counter for 8 hours, and heat a cast iron pot in the oven to very hot, and then dump the dough into the hot pot and put the lid on. I read long threads about that method where they rave about it. Should be somewhere online.

In your shoes, I might still consider going back on gluten for the diagnosis. my daughter did , despite of awful symptoms. She did get a diagnosis despite of negative tests because of these terrible symptoms on gluten and that they all went away off gluten. We get about 200dollars a month with an official diagnosis.

      That and my nutritionist also said that drinking cider is one of the worst drink choices for me, given that I have candida overgrowth.  She said the combination of the alcohol and sugar would be very likely to worsen my candida problem.  She suggested that if I drink, I go for clear vodka, either neat or with a splash of cranberry.   So in summary, I am giving ciders a rest.  Whether it's a gluten risk or sugars and yeast overgrowth, its just not worth it.

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. 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. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.

      Welcome to the community! Generally, for a gluten challenge before celiac disease blood tests, Tylenol (acetaminophen) is considered safe and should not interfere with your antibody results. The medications you typically need to avoid are those like ibuprofen (Advil, Motrin) or naproxen (Aleve) that can cause intestinal irritation, which could potentially complicate the interpretation of an endoscopy if you were to have one. However, it is absolutely crucial that you confirm this with either your gastroenterologist or your surgeon before your procedure. They know the specifics of your case and can give you the definitive green light, ensuring your surgery is comfortable and your celiac testing remains accurate. Best of luck with your surgery tomorrow
