Has anyone done a successful gluten challenge for testing?

My GI wants to test me for celiac. I have microscopic colitis, osteopenia and lactose intolerance.

I have been gluten-free for several years now. My doctor says maybe I haven't done a very good job because of cross contamination.

I need to do a gluten challenge to be tested.

Has anyone done a challenge successfully for testing? I know the rate of false negatives is high.

I am on week 4.  She is going to do the biopsy first since the blood takes longer to register then we'll do that after.

What did you eat? Does it matter whether it is whole wheat or white bread? What are the best foods? How about soft pretzels? How much? There doesn't seem to be an agreement even among the experts.

Please share your experiences on what you did (ate and for how long) I know for some adults it can be up to a year.

It is important to me because if it is positive it can impact my children and my likelihood of other diseases.

Thank you in advance for your insights.

Oh, if you show damage but not enough Marsh 3 did they call it negative, or did they decide it wasn't long enough?

Half a slice of bread at least a day, some have used a few tsp of pure wheat germ or wheat gluten. If you show any damage period that is a sign you have celiac, if you show no damage consider the size of your intestines and the chance they could have missed it. There is also the condition NCGS that could be the issue.

 I opted out of my last gluten challenge retest...my symptoms are so severe and apparent it is not worth it and life threatening. If the doctor insist I might consider eating a monte cristo or pizza in the doctors office, they can observe me lose motion control collapse on the floor and start vomiting unable to move hoping I do not choke on the floor like last time.  But I would require substantial monetary compensation to even consider the act first.

okay first i would start w different gi doc bc if you are going get tested you should not be gluton free! that will affect test! as for bread u hv eat gluton free bread if u are celiacs! gluton is in or is flour its not  its just weat! flour is in alot of things! some plp that hv celiacs are allergic to dairy. i know alot abt this bc several plp including me in my life that are celiacs! things to avoid would be salads w croutons, most soups out bc the broth made w flour, all bread unless its specified gluton freee n baked goods unless otherwise specified gluton free!

Hi Tootie!  

Four weeks of consuming 1 to 2 slices of bread (or equivalent) should be enough  time for an endoscopy per all the experts.  The blood test requires a much longer period of 8 to 12 weeks.  I would go as long as possible, if you can stand it.  Some people develop antibodies fast and others develop them slowly (it can take a long time for them to diminish as well).   It is one  of the reasons that there is no consensus among celiac experts ( that and a lack of studies).  It is good that you are under  a doctor's care.

Eat cake, sourdough, cookies..... all your favorite foods.   I did that between my blood test and biopsy.  I just had anemia, but after gorging on gluten filled foods, by the end of seven weeks, I could tell that gluten was not good for me.  My biopsies confirmed this.   I was also willing to give up gluten for life too. 

Because we are all unique, healing times vary.

Thank you.

I am going to try to go 12 weeks before the biopsy. I want to get the biggest bang for my buck with what I eat, because I fear this may just be a waste of time. So that is why I am asking what people ate that avoided a false negative.

I have read anywhere from 1/2 slice of bread to 4-6 slices of bread. Some sites say white bread has more gluten? But I've been eating whole wheat. I've also been considering seitan (which is basically vital wheat gluten- vegan meat apparently)

From the studies I've read only 50-85% of known celiacs test positive within 3 months. Ugg. Probably lower for others.

My GI said if the biopsy is result questionable because of time (some damage, but not enough) we could do the gene testing as well. I know that test only rules it out, not in.

Whatever the result is, I just want to be confident that it is accurate, but that is probably not possible.

You say you have been gluten free for several years. Have you noticed any increase in symptoms, even not GI related, since you went back on gluten 4 weeks ago?  As far as how much to eat if you can tolerate it just go with a regular gluten filled diet for the rest of the challenge. If you are having severe symptoms then just a couple slices of bread might be enough. Use the time to go to your favorite restaurants and eat your favorite gluten filled foods that you might have missed while you were gluten free.  As far as the chance that you might have been getting CC previously do check out the Newbie 101 thread at the top of the Coping section. You may be able to spot stuff you have or haven't been doing that could have been CCing you. I hope you get clear answers when you get your testing done.

Did you have symptoms that went away and now they are back? 

And why did you go gluten-free in the first place? Did you suspect celiac and not get tested? Why test now?

I am getting tested now because I am currently seeing a GI because I developed chronic watery D for 6 months now. I had a biopsy of my colon and was positive for lymphocytic colitis for which they have no cure. The GI said there is a high correlation between celiac and LC and since I have other issues that could correlate I should be tested. (osteopenia and lactose intolerance).

I originally stopped gluten because I took my son off it due to a ruptured stomach and gerd also possible ASD tendancies. I started with him in solidarity and because I won't require them to do anything I wouldn't do myself. But after a time, I found I felt better and my arthritis pain went away and I haven't developed a bone spur since I stopped, which I was getting in my fingers regularly. So I remained gluten free.

Since I started back a month ago, the symptoms haven't been horrible. Some of these could just be coinsidence, not related to the gluten.  I have intermittent abdominal pain, still have D, extreme gas and bloating to the point I feel like my abdomen could actually pop, lol, headaches (which I never get) but have had them every day, an upper eyelid twitch like tightening (but only when I blink)  and a slight numbness around the same eye (comes and goes), feels like food gets stuck in my throat. Also, fatigue but that is likely due to all the carbs I've been eating, because I was low carb before so I think I'm just not used to it.

Hey There.

I was successfully diagnosed Coeliac a few months ago after 11 years of false negatives.

This came after a positive match for villus atrophy with a gastroscopy/biopsy.

I ate pies, toast, sausage rolls and pasta every day for 4 weeks. I did get very sick and the blood results came back positive for the antibodies.

I was also tested positive for the gene to confirm that it was possible for me to be Coeliac in the case that there was another negative antibody test,

which I would recommend you do if you have nowhere left to turn.

Wow. 11 years? How many times did you test? Did you have more than one biopsy? Was it because you were gluten free before testing? My GI did mention the genetic testing if necessary. I'm glad you finally got your diagnosis.

      Shingles - Could It Be Related to Gluten/ Celiac

      By Scott Adams · Posted

      I had the same thing happen to me at around your age, and to this day it's the most painful experience I've ever had. For me it was the right side of my head, above my ear, running from my nerves in my neck. For years before my outbreak I felt a tingling sensation shooting along the exact nerves that ended up exactly where the shingles blisters appeared. I highly recommend the two shot shingles vaccine as soon as your turn 50--I did this because I started to get the same tingling sensations in the same area, and after the vaccines I've never felt that again.  As you likely know, shingles is caused by chicken pox, which was once though of as one of those harmless childhood viruses that everyone should catch in the wild--little did they know that it can stay in your nervous system for your entire life, and cause major issues as you age.

      Gluten free nuts

      By Clear2me · Posted

      Thanks for the info. I recently moved to CA from Wyoming and in that western region the Costco and Sam's /Walmart Brands have many nuts and more products that are labeled gluten free. I was told it's because those products are packaged and processed  in different  plants. Some plants can be labeled  gluten free because the plant does not also package gluten products and they know that for example the trucks, containers equipment are not used to handle wheat, barely or Rye. The Walmart butter in the western region says gluten free but not here. Most of The Kirkland and Members Mark brands in CA say they are from Vietnam. That's not the case in Wyoming and Colorado. I've spoken to customer service at the stores here in California. They were not helpful. I check labels every time I go to the store. The stores where I am are a Sh*tshow. The Magalopoly grocery chain Vons/Safeway/Albertsons, etc. are the same. Fishers and Planters brands no longer say gluten free. It could be regional. There are nuts with sugar coatings and fruit and nut mixes at the big chains that are labeled gluten free but I don't want the fruit or sugar.  It's so difficult I am considering moving again. I thought it would be easier to find safe food in a more populated area. It's actually worse.  I was undiagnosed for most of my life but not because I didn't try to figure it out. So I have had all the complications possible. I don't have any spare organs left.  No a little gluten will hurt you. The autoimmune process continues to destroy your organs though you may not feel it. If you are getting a little all the time and as much as we try we probably all are and so the damage is happening. Now the FDA has pretty much abandoned celiacs. There are no requirements for labeling for common allergens on medications. All the generic drugs made outside the US are not regulated for common allergens and the FDA is taking the last gluten free porcine Thyroid med, NP Thyroid, off the market in 2026. I was being glutened by a generic levothyroxin. The insurance wouldn't pay for the gluten free brand any longer because the FDA took them all off their approved formulary. So now I am paying $147 out of pocket for NP Thyroid but shortly I will have no safe choice. Other people with allergies should be aware that these foreign generic pharmaceutical producers are using ground shellfish shell as pill coatings and anti-desicants. The FDA knows this but  now just waits for consumers to complain or die. The take over of Wholefoods by Amazon destroyed a very reliable source of good high quality food for people with allergies and for people who wanted good reliably organic food. Bezos thought  he could make a fortune off people who were paying alot for organic and allergen free food by substituting cheap brands from Thailand. He didn't understand who the customers were who were willing to pay more for that food and why. I went from spending hundreds to nothing because Bezo removed every single trusted brand that I was buying. Now they are closing Whole foods stores across the country. In CA, Mill Valley store (closed July 2025) and the National Blvd. store in West Los Angeles (closed October 2025). The Cupertino store will close.  In recent years I have learned to be careful and trust no one. I have been deleberately glutened in a restaurant that was my favorite (a new employee). The Chef owner was not in the kitchen that night. I've had  a metal scouring pad cut up over my food.The chain offered gluten free dishes but it only takes one crazy who thinks you're a problem as a food fadist. Good thing I always look. Good thing they didn't do that to food going to a child with a busy mom.  I give big tips and apologize for having to ask in restaurants but mental illness seem to be rampant. I've learn the hard way.          I don't buy any processed food that doesn't say gluten free.  I am a life long Catholic. I worked for the Church while at college. I don't go to Church anymore because the men at the top decided Jesus is gluten. The special hosts are gluten less not gluten free. No I can't drink wine after people with gluten in their mouth and a variety of deadly germs. I have been abandoned and excluded by my Church/Family.  Having nearly died several times, safe food is paramount. If your immune system collapses as mine did, you get sepsis. It can kill you very quickly. I spent 5 days unconscious and had to have my appendix and gall bladder removed because they were necrotic. I was 25. They didn't figure out I had celiac till I was 53. No one will take the time to tell you what can happen when your immune system gets overwhelmed from its constant fighting the gluten and just stops. It is miserable that our food is processed so carelessly. Our food in many aspects is not safe. And the merging of all the grocery chains has made it far worse. Its a disaster. Krogers also recently purchased Vitacost where I was getting the products I could no longer get at Whole Foods. Kroger is eliminating those products from Vitacost just a Bezos did from WF. I am looking for reliable and certified sources for nuts. I have lived the worst consequences of the disease and being exposed unknowingly and maliciously. Once I was diagnosed I learned way more than anyone should have to about the food industry.  I don't do gray areas. And now I dont eat out except very rarely.  I have not eaten fast food for 30 years before the celiac diagnosis. Gluten aside..... It's not food and it's not safe.  No one has got our backs. Sharing safe food sources is one thing we can do to try to be safe.

      Thank you kindly for your response. I have since gotten the other type of bloods done and am awaiting results.
