How long to eat gluten before blood test

Hello, I have been eating gluten for 24 years with no diagnosis of celiac. I have always had stomach problems but never got checked out. Recently, I tried a gluten free diet and I feel a lot better with symptoms improving. My PCP just gave me a blood test order and he told me to go back to eating gluten for 1 week before I get tested. I've been gluten free for just over a month. Is 1 week long enough to get a valid result?

No. The mayo clinic official recommendation for the gluten challenge leading up to the serum antibody test is to consume an amount of gluten equivalent to 2 slices of wheat bread daily for 6-8 weeks.

The Mayo clinic recommends eating at least 2 slices of bread for 6-8 weeks before a blood screening for celiac disease, and 2 weeks for an endoscope:

Can I get the biopsy without the blood test?

The normal protocol would be to get the blood panel done first:

and if you have positive results, possibly get a biopsy after.

I know that's the norm but is it possible to just ask for a biopsy if I can't eat gluten for 6-8 weeks

Certainly! That is if your physician is willing to go that route. Actually, the biopsy is considered the gold standard of celiac diagnosis. Physicians may be bound by insurance guidelines, however, that demand they do the much less expensive serum antibody testing first.

I don’t think you should put yourself through torture to see if you are gluten intolerant.   If gluten makes you sick, then you are gluten intolerant.  You don’t need to have a gene for it.  It can happen to anyone at any time.  If other grains like rice make you sick too, then you can give them up too.  You don’t need any grains at all.  Also, if the test comes back negative, are you going to eat gluten again?  Of course not because gluten makes you sick.  The test is just a waste of time and money.  Also you might make yourself severely sick.

      Gluten-Free Diet Linked to Reduced Inflammation and Improved Outcomes in Multiple Sclerosis (+Video)

      I worried at one point on my journey whether I had MS, having many of the symptoms myself. However, my symptoms improved dramatically with high dose thiamine hydrochloride, Benfotiamine, and Thiamine TTFD. Thiamine deficiency symptoms overlap with MS symptoms, including changes on brain MRIs. Thiamine deficiency affected my eyes (light sensitivity),...

      Unexpected gluten exposure risk from cultivated mushrooms

      Welcome to the celiac.com communiuty, @Matthias! Yes, we have been aware that this can be an issue with mushrooms but as long as they are rinsed thoroughly it should not be a problem since the mushrooms don't actually incorporate the gluten into their cellular structure. For the same reason, one needs to be careful when buying aged cheeses and products...

      Unexpected gluten exposure risk from cultivated mushrooms

      The one kind of food I had been buying and eating without any worry for hidden gluten were unprocessed veggies. Well, yesterday I discovered yet another pitfall: cultivated mushrooms. I tried some new ones, Shimeji to be precise (used in many asian soup and rice dishes). Later, at home, I was taking a closer look at the product: the mushrooms were growing...

      IBS-D vs Celiac

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that y...

Yes, we have been aware that this can be an issue with mushrooms but as long as they are rinsed thoroughly it should not be a problem since the mushrooms don't actually incorporate the gluten into their cellular structure. For the same reason, one needs to be careful when buying aged cheeses and products containing yeast because of the fact that they are sometimes cultured on gluten-containing substrate.

      The one kind of food I had been buying and eating without any worry for hidden gluten were unprocessed veggies. Well, yesterday I discovered yet another pitfall: cultivated mushrooms. I tried some new ones, Shimeji to be precise (used in many asian soup and rice dishes). Later, at home, I was taking a closer look at the product: the mushrooms were growing from a visible layer of shredded cereals that had not been removed. After a quick web research I learned that these mushrooms are commonly cultivated on a cereal-based medium like wheat bran. I hope that info his helpful to someone.

Incidentally, I don't like quinoa either. Reminds me and smells to me like wet grass seed. When its not washed before cooking it makes me ill because of saponins in the seed coat. Yes, it can be difficult to get much dietary calcium without dairy. But in many cases, it's not the amount of calcium in the diet that is the problem but the poor uptake of it. And too much calcium supplementation can interfere with the absorption of vitamins and minerals in general because it raises gut pH.

      IBS-D vs Celiac

      By Scott Adams · Posted

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that you carry HLA-DQ2.2 means celiac disease is absolutely possible, even if it’s less common than DQ2.5, and many people with DQ2.2 present later and are under-diagnosed. Your hesitation to reintroduce gluten is completely understandable — quality of life matters — and many people in your position choose to remain strictly gluten-free and treat it as medically necessary even without formal biopsy confirmation. If and when you’re ready, a physician can help you weigh options like limited gluten challenge, serology history, or documentation as “probable celiac.” What’s clear is that this wasn’t just random IBS — you identified the trigger, and your body has been very consistent in its response.
