Can Celiac Bloodwork Change?

Hi, my husband has celiac, and we kept my daughter gluten-free til about 12 months of age. Then around age 2, Dr did the bloodwork that came out completely negative (I was told) We have changed pediatricians since then, and my current dr doesn't have those records.

Now, my daughter is a very healthy 9 year old, but has been having sharp tummy pains off and on = usually middle of the day, sometimes in her back she says, maybe lasting 1-3 minutes.

So, my question is - if the bloodwork came out negative at age 2, would that change to now? Doesn't it check for genetic predisposition?

Current dr is going to order new bloodwork just to be sure.

Hello and welcome!

Depending on what type of tests they ran on your daughter, yes they can change. At two years old, blood tests are often inaccurate. If they did a genetic test, that would show whether she carried the genetic marker for Celiac, but many people carry the marker and do not ever develop Celiac.

If they only did blood tests, having her retested was a great idea. It takes time for the intestinal damage to occur to the point that it shows up on the tests if, in fact, she does have Celiac.

Please stick around and make yourself at home. Ask any questions; there are so many people here with so many different stories that can really be a great deal of support.

blood work can change for a number of reasons. here are four that apply to your case:

1. tests in children under two are unreliable and generate false negatives at a higher than normal rate

2. celiac isn't "on" from birth - it can develop at any age; tests before that will be negative, after will be positive

3. tests from different labs use different reference ranges; the same result may show positive for some labs, negative for others

4. it may take time for enough damage to occur for the antibodies that are usually tested for (they don't usually do genetic tests) to show up in the blood stream

WOW, just found the ped that ran the original results and faxed them to me.

Endomysial Antibioties, IgH - None Det

Endomysial Antibiodies, IgA - None Det

Transglutiminase IGA Autoantibiodies = < 10 U/ML (Reference Range <10)

Endomysial Antiboidies, IgA G None Det

Anyone care to interpret for me?!?!?!

THANKS SO MUCH for all your input!

So does this mean she should be tested yearly? (Providing that this time we come back with negative results?)

If she has suspicious symptoms, absolutely. Otherwise, probably not. She may never develop Celiac, and stressing about something that may never happen isn't good for you either.

Obviously, your daughter has developed suspicious symptoms. Sharp stomach pains sure aren't normal! If her tests come back negative, I would have her tested with Open Original Shared Link, as their tests will detect antibodies BEFORE the villi are pretty much destroyed, while the blood tests are only accurate when there is lots of villi damage already.

And, of course, there is always the most accurate test of them all, which is trying the gluten-free diet to see if those stomach problems go away.

How old was she again when tested? Did they run a total iga count? IF she is IGA deficient, then some of the Celiac tests will come back negative no matter what since they depend on IgA numbers. I'm wondering why nothing was detected. Even my daughter's .1 was recorded on her lab results. But if this was several years ago as I think I read, then that may be all they did then. Our latest results had the following tests run

Anti-gliadin IgG ELISA (AGA IgG)

Anti-gliadin IgA ELISA (AGA IgA)

Anti-human Tissue Transglutaminase Iga Elisa (TTG IgA)

Anti-Endomysial IgA IFA (EMA IgA)

TOtal Serum IgA by NEphelometry (TOTAL IgA)

We had one run 4 days off of wheat and one run 68 days on wheat. The numbers went up some. We will have another run at some point to see if they go down.

i was told to make sure the lab used was Prometheus since they do a lot of this type of testing. And to make sure you get a total Iga count to make sure that is normal.

Well if you keep them gluten free and then get bloodwork done then the it is likely that the bloodwork will show up negative. That is the way they keep track of how celiacs are doing with their diet. Like when I had blood tests done that showed positive they checked me after being gluten free for 6 months and it came back negative and thats the way they monitor compliance because not everyone can tell from symptoms.

I checked back at the records. We kept her gluten-free till about 10 months. Her weight was dropping a little bit and the dr was worried that she wasn't getting enough to eat. Knowing that a gluten-free diet would not show up on a bloodtest, we put her on reg food, and at 13 months did the bloodwork. (4 months on reg food)

I repeatedly asked the pediatrician over the years if the test needed to be re-done, and every one told me NO, that bloodwork doesn't change.

Now, Im mad at myself for not persuing it further.

I only have results from those 3 tests done in 2000. The "interpretative data" sasy - Endomysial antiboides are screened using an ELISA tissue transglutiminase (tTg) assay. All samples wich are positivtitered by IFA. The endomysial antigen has been identified protien cross-linking enzyme known as tissue transglutimines

Here in Holland I think at least some doctors recommend that family members be tested every five years or so, unless they have suspicious symptoms and should be tested sooner. Why don't you just request the blood tests now, just in case?

Here in the US , they only "recognize" two Celiac genes--but in Europe, I think they recognize 7 genes as being associated with celiac. Definitely something to keep in mind!

I totally agree that sharp tummy pains are NOT normal. Something is causing them.

My kids' occasional tummy pains disappeared on a gluten-lite diet (I was gluten-free, and didn't want to cook 2 dinners or breakfasts, so they only had gluten in their school lunches)--that clued me in to the need to have them go totally gluten-free.

Even though your husband is Ceoliac, it could be possible that your daughter isn't ceoliac... She still may however be Gluten Intolerant..

There is only a small number of people that are ceoliac...

I am Ceoliac, but my sister is only Gluten Intolerant...

      Taken Seriously

      By Scott Adams · Posted

      Your post demonstrates the profound frustration and isolation that so many in the Celiac community feel, and I want to thank you for channeling that experience into advocacy. The medical gaslighting you endured for decades is an unacceptable and, sadly, a common story, and the fact that you now have to "school" your own GI specialist speaks volumes about the critical lack of consistent and updated education. Your idea to make Celiac Disease a reportable condition to public health authorities is a compelling and strategic one. This single action would force the system to formally acknowledge the prevalence and seriousness of the disease, creating a concrete dataset that could drive better research funding, shape medical school curricula, and validate the patient experience in a way that individual stories alone often cannot. It is an uphill battle, but contacting representatives, as you have done with Adam Gray, is exactly how change begins. By framing it as a public health necessity—a matter of patient safety and protection from misdiagnosis and neglect—you are building a powerful case. Your voice and your perseverance, forged through thirty years of struggle, are exactly what this community needs to ensure that no one else has to fight so hard just to be believed and properly cared for.

      Allergy medication: cetirizine by the HealthA2Z is it gluten free?

      By Scott Adams · Posted

      Navigating medication safety with Celiac disease can be incredibly stressful, especially when dealing with asthma and severe allergies on top of it. While I don't have personal experience with the HealthA2Z brand of cetirizine, your caution is absolutely warranted. The inactive ingredients in pills, known as excipients, are often where gluten can be hidden, and since the FDA does not require gluten-free labeling for prescription or over-the-counter drugs, the manufacturer's word is essential. The fact that you cannot get a clear answer from Allegiant Health is a significant red flag; a company that is confident its product is gluten-free will typically have a customer service protocol to answer that exact question. In situations like this, the safest course of action is to consider this product "guilty until proven innocent" and avoid it. A better alternative would be to ask your pharmacist or doctor to help you identify a major national brand of cetirizine (like Zyrtec) whose manufacturer has a verified, publicly stated gluten-free policy for that specific medication. It's not worth the risk to your health when reliable, verifiable options are almost certainly available to you. You can search this site for USA prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/

      Protein or fat?

      By Scott Adams · Posted

      What you're describing is indeed familiar to many in the Celiac community, especially in the early stages of healing. When the intestinal villi are damaged from Celiac disease, they struggle to properly digest and absorb fats, a condition known as bile acid malabsorption. This can cause exactly the kind of cramping and spasms you're seeing, as undigested fats can irritate the sensitive gut lining. It is highly plausible that her reactions to dairy and eggs are linked to their higher fat content rather than the proteins, especially since she tolerates lean chicken breast. The great news is that for many, this does improve with time. As her gut continues to heal on a strict gluten-free diet, her ability to produce the necessary enzymes and bile to break down fats should gradually return, allowing her to slowly tolerate a wider variety of foods. It's a slow process of healing, but your careful approach of focusing on low-fat, nutrient-dense foods like seeds and avocado is providing her system the best possible environment to recover. Many people with celiac disease, especially those who are in the 0-2 year range of their recovery, have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy. The good news is that after your gut heals (for most people who are 100% gluten-free this will take several months to two years) you may be able to slowly add some these items back into your diet after the damaged villi heal. This article may be helpful: Thank you for sharing your story—it's a valuable insight for other parents navigating similar challenges.

      Diagnosed celiac for 1-2 months ago and everything makes me bloated.

      By Beverage · Posted

      I had a very rough month after diagnosis. No exaggeration, lost so much inflammatory weight, I looked like a bag of bones, underneath i had been literally starving to death. I did start feeling noticeably better after a month of very strict control of my kitchen and home. What are you eating for breakfast and lunch? I ignored my doc and ate oats, yes they were gluten free, but some brands are at the higher end of gluten free. Lots of celics can eat Bob's Red Mill gluten-free oats, but not me. I can now eat them, but they have to be grown and processed according to the "purity protocol" methods. I mail order them, Montana Gluten-Free brand. A food and symptoms and activities log can be helpful in tracking down issues. You might be totally aware, but I have to mention about the risk of airborne gluten. As the doc that diagnosed me warned . . Remember eyes, ears, nose, and mouth all lead to your stomach and intestines.  Are you getting any cross contamination? Airborne gluten? Any pets eating gluten (they eat it, lick themselves, you pet them...)? Any house remodeling? We live in an older home, always fixing something. I've gotten glutened from the dust from cutting into plaster walls, possibly also plywood (glues). The suggestions by many here on vitamin supplements also really helped me. I had some lingering allergies and asthma, which are now 99% gone. I was taking Albuterol inhaler every hour just to breathe, but thiamine in form of benfotiamine kicked that down to 1-2 times a day within a few days of starting it. Also, since cutting out inflammatory seed oils (canola, sunflower, grapeseed, etc) and cooking with real olive oil, avocado oil, ghee, and coconut oil, I have noticed even greater improvement overall and haven't used the inhaler in months! It takes time to weed out everything in your life that contains gluten, and it takes awhile to heal and rebuild your health. At first it's mentally exhausting, overwhelming, even obsessive, but it gets better and second nature.
