My daughter was tested at her annual appointment when she turned 4 because her brother has celiac's. She has no symptoms. She eats a lot of gluten. 

Blood work round #1 March 2024: 

-          Endomysial IgA Ab: Negative  (Range: Negative)

-          Gliadin IgA: <10.0 U/ml  (Range: <20.0 Negative)

-          IGA: 93.43 mg/dL  (Range: 27.00 - 195.00)

-          TISSUE TRANSGLUTAMINASE IGA: 9.1 U/ml  (Range: <4.0) *** this was high. the range changes for the next one, but it was noted that it was about double the range. 

We went for an endoscopy in May 2024 and it was negative. 

Blood work round #2 October 2024:

-          ENDOMYSIAL ANTIBODY TITER: 1:5 titer  (Range: <1:5) **flagged as high

-          ENDOMYSIAL ANTIBODY SCR (IGA) W/REFL TO TITER: POSITIVE  (Range: NEGATIVE) **flagged because its not negative

-          IMMUNOGLOBULIN A  TISSUE TRANSGLUTAMINASE AB, IGA:  28.8U/mL  (Range: 22 – 140.  <15.0  =Antibody not detected. >or= 15.0 =Antibody detected.) **flagged high but the ratio/range was different and about double. Note says: Serological evidence for celiac disease is present.

Blood work round #3 January 2025:

-          TTG IGA: 28.1U/mL  (Range: 22 – 140.  <15.0  =Antibody not detected. >or= 15.0 =Antibody detected.)

Now we are scheduling another endoscopy. My main concern right now is if the endoscopy is negative again…where does that leave us??? Public Schools and daycare will not feel her gluten free if its not an official diagnosis.

Since she is asymptomatic and her first biopsy was negative I would not assume she has developed celiac disease. If her upcoming biopsy shows evidence of mucosal damage you have the firm evidence you need to trigger the gluten-free protocol at the preschool. There are other causes for mildly elevated tTG-IGA levels besides celiac disease. Studies are all over the map with this statistic but there is somewhere between a 10% and an almost 50% chance that your daughter will develop celiac disease since she has a first degree relative who is a celiac (her sister).

The important thing in this scenario is to continue to monitor the situation via testing and symptoms. You are already doing this so kudos to you and your doctors.

But one question I have is, are the blood samples being tested by the same lab in each case? Different labs build these tests a little differently and there is no industry standard. So, to compare her tTg-IGA test scores from one time to the other is only useful if the analysis is being handled by the same lab.

The first lab was different because Allina switched which lab they work with in between March and October. But October and January were the same lab. All through Allina but two separate labs.

I lean towards very probably celiac disease due to the two positive tTg-IgA blood tests. Although there are other things that might cause this test to be elevated in certain individuals, the most likely cause by far would be gluten sensitivity. 

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.

Have you and you and the children's father been tested?

We have been tested and tested negative. But we have not done the gene testing.

I hope you don't have to wait too long until her endoscopy. Is she able to bring her lunch with her in the meantime?

We had the follow up endoscopy 1 year out from the first one. We left that day and they said visually it looked good so he thought she'd be negative again. Results came back this week as celiac sprue present and level Marsh 3A. So she doesn't have much damage but she is now positive for celiacs... Just thought I'd post in case in takes anyone else a year to get a diagnosis. :)

It's too bad they didn't diagnose her based on the positive tTg-IgA blood tests + family history. Marsh 3A does confirm celiac disease, but it’s great that the damage isn’t extensive! Even with moderate changes, symptoms can vary widely. Strict gluten-free eating should help heal the gut over time.

      Has someone experienced discrimination because of their illness?

      Regarding the discrimination you asked about, it is a lot more easy now to discriminate when you're supposed to answer whether or not you have celiac disease on job applications, and from what I've seen, MANY companies now include this question on their applications:

      When Home Isn't Safe: Celiac Disease, Cross-Contamination, and the Right to a Gluten-Free Space

      It's too bad relationships end because of this disease, but I suppose that being healthy may be more important than being married or living with someone who isn't on board with the gluten-free diet.

      When Home Isn't Safe: Celiac Disease, Cross-Contamination, and the Right to a Gluten-Free Space

      This is a huge topic. My ex husband didn't care. Even though I had my own area where his food wasn't allowed, I'd find crumbs. I was always constantly cleaning. I threw a lot of food away because I wouldn't be sure if he had contaminated it. It really showed what a narcissistic person he was and is. Now I'm in my own home. Much better. I do have dogs...

      Fiber-Metabolizing Bacteria Could Boost Gut Health in Celiac Disease

      People with coeliac disease have an altered gut biome compared with those who do not, which may be associated with gut inflammation. Although the gut biome recovers on a gluten-free diet, there are still significant differences at 2 years.

      Shaking/Tremors and Off Balance

      Hi Ginger38 Well done you for pushing through the pain barrier of eating gluten, when you know each mouthful is making you poorly. I went through the same thing not long ago, my biopsy was for dermatitis herpetiformis. Result positive, so 95% certain I have gut coeliacs too. But my bloods were negative, so very pleased I went for the gluten challenge...

Although the gut biome recovers on a gluten-free diet, there are still significant differences at 2 years. In a mouse model of coeliac disease, supplementation with the soluble dietary fibre, inulin, increased the number of beneficial microbes and reduced gut inflammation. Inulin is used by some plants as carbohydrate store, it is a complex polymer of fructose in the same way that starch is a complex polymer of glucose. Inulin cannot be digested by humans but serves as food source for some gut bacteria. Inulin is present in many vegetables but the richest sources are (g/100g): chicory root 41.6 Jerusalem artichoke 18.0 dandelion greens 13.5 garlic 12.5 leeks 6.5 onions 4.3 The Scientist: Fiber-Metabolizing Bacteria Could Boost Gut Health in Celiac Disease

      Has someone experienced discrimination because of their illness?

      By Scott Adams · Posted

      When symptoms like fatigue, brain fog, or low energy change how we interact, others sometimes misinterpret that as disinterest, rudeness, or negativity—especially if they don’t understand the underlying condition. That doesn’t make their behavior okay, though. You don’t deserve to be treated poorly for something outside your control. Often, it reflects a lack of awareness or empathy on their part, not a fault in you. It can help to explain your condition to people you trust, but it’s also completely valid to set boundaries and distance yourself from those who respond with hostility. Your experience—and your reaction to it—makes sense. The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium.  Unfortunately many doctors, including my own doctor at the time, don't do extensive follow up testing for a broad range of nutrient deficiencies, nor recommend that those just diagnosed with celiac disease take a broad spectrum vitamin/mineral supplement, which would greatly benefit most, if not all, newly diagnosed celiacs. Because of this it took me decades to overcome a few long-standing issues I had that were associated with gluten ataxia, for example numbness and tingling in my feet, and muscle knots--especially in my shoulders an neck. Only long term extensive supplementation has helped me to resolve these issues.

      HLA-DQ2 POSITIVE it's nothing

      By Scott Adams · Posted

      Being HLA-DQ2 positive doesn’t diagnose celiac disease by itself, but it does mean he has the genetic potential for it, so it absolutely deserves careful follow-up if symptoms or concerns are present. You’re right that celiac is often downplayed, but it’s a serious autoimmune condition—not an allergy—and it can affect the brain, nervous system, and overall health if untreated. Given everything your son has been through, you’re doing the right thing by advocating and asking questions. I would strongly recommend getting a full copy of his records, and if possible, consulting a gastroenterologist who understands celiac disease well so you can get clear answers and, if needed, proper testing and monitoring.
