Help, blood work, false negative?

Hello everyone and btw please excuse me if my english is bad ): ! the idea of having celiac has been around my head since a significant time ago, i have anti thyroid autoantibodies and a borderline t4 and tsh, dry eye, multiple joint and muscle pain, acid reflux, stomach pain, diarrhea alternated with constipation, floating and weird stoles, psoriasis, nausea, dizziness, vitamin A deficit, vitamin b12 decifit, vitamin D deficit, random bleeding from lady parts, not related to ovulation, menstruation or anything, im tired all the time and im done feeling like crap everyday, my medic of course suspect celiac so i have a blood work done, it come back negative, i also had what i think was herpetiform dermatitis, sadly i didn't know about it at that time and as i have psoriasis gutata too and it looks kind of similar i think it was the same thing at the beginning, they were blisters that itch a lot on my knees, i should have gone to the doctor but now its too late since they are gone so i cant, the thing is, i was gluten free almost 100% for a very long time, it was kind of intuitive, i didn't think i had celiac at that point, but notice a significant difference eating that way so i "follow my instinct", the dermatitis and psoriasis disappear, later i started consuming gluten once in a while but not in a regular way, maybe one week i eat something, the next week anything, etc etc (i had symptoms this way and thats why i went to the doctor), i was told by my doctor to eat gluten for at least two weeks before the blood work, and i was so bad that i had to go to the urgency's, a lot of stomach pain and constipation, fever, diarrhea, it was hell, so i eat as much as i can but maybe not as regular as i should, Now that i see that all antibodies are completely normal i feel lost and crazy, should i do the biopsy anyway? i dont know any other way to explain the multiple vitamin deficit since i eat really healthy, could this have to be with the fact that i was gluten free for a long time? (the absence of antibodies) even tho i consume gluten once in a while at those times? every antibody come back negative and i had a total IGA and im not deficient. I dont know what to think, i was on my period when blood work was done and i also had flu like syntoms, my immune system was hitting rock bottom as always on these days, maybe that's the reason? idk what to think really... any advice or thought

If a person with Celiac is eating gluten-free, then the antibodies should be negative.  It sounds like you were gluten-free, so you wouldn't expect to have any antibodies.

Thanks for your answer, i was eating gluten before the test, my doctor said i should eat at least two weeks and that's what i did, but not everyday, since i had to stop for 2 or 3 days because of awfull symptoms, i should eat gluten for 12 weeks? that is a lot, :S, in the page you quoted said that 2 weeks is okay for biopsy but blood work takes more, so you can have enought damage on your insides before having antibodys? on the antitransglutaminasa IGG i got 6,9 , 10 is considered positive, even tho is negative is not 0, could it mean something? btw when i ate gluten those 2 weeks i eat full meal, not slices of bread so i thought it would take less time for antibodys to build up, idk

Two weeks (experts say 2 to 4 weeks) on a gluten challenge can be enough to obtain tissue samples (biopsy) through an endoscopic procedure.  I  am sorry that your doctor is not knowledgeable about celiac disease.  Karen is right that it's about 12 weeks for the blood tests.

The intestines can be damaged rather quickly if you have celiac disease, but it takes time for antibodies to build and circulate in the blood.  Your blood result?  Most people never have a 0.  You need to go above the range (in your case a "10").

Two weeks may not be enough of a challenge.  Figure 2 in this paper:

shows a very slight increase in some antibody levels at two weeks but it really took four weeks for the bigger increase.  If you're so sick during the challenge it certainly says that your body can't handle gluten.

Thanks everyone, the graphic was very interesting!, ill keep eating gluten in case i need a biopsy but im unable to keep a diary intake, do i have to eat gluten absolutely everyday? im going to talk with my doctor and see if he HOPEFULLY want to recheck my blood in a moth or so, to see if antibodies build up on me, but im worry he send me back home with a "you are not celiac, you just have ibs" , at least i hope he wants to do the biopsy, he also send me quite a disgusting study that checks for steatorreah, i have to eat 100 gr of butter everyday for 5 days and then collect the last 2, any experience on this subject? Van de Kamer is called i think... im scared because it sounds so aggressive even for a healthy bowel and in general oily food make me feel sick u.u

      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.
