Daughter's Anti Ttg Results - What Does This Mean?

My 7.5 year old daughter has been having stomach pain. She is quite tall for her age and very thin. She also has an IgG response to dairy, so our GI doc told me he was testing her for Celiac.

Here are the results as they pertain to Celiac:

Anti tTG IgA = 6

IgA (total?) = 92

What do these numbers make you think?

Every lab uses a different scale for measuring the results. It's hard to tell what those numbers mean without the reference ranges. Can you look at the results again and post the ranges? It will tell you what is positive, what is negative and what is in the equivocal range.

Unfortunately, the sheet faxed to me does not include the range. The tTG result does have an asterisk, indicating it is out of range. The IgA does not.

Makes me think some ding a ling office medical clerk didn't understand that you need the entire page of the lab report. :blink:

Try calling them back and sweet talking them into copying it the old fashioned way, or cutting and pasting it onto a file they can then copy, if they say they can't, tell them you paid for it, you own it, cough up the full results. Or go to the office and get a copy.

My car is rolling down the hill at 50. 50 what ? What country am I in, is it mph or kpm, and what's the speed limit, anyway ?

IgA (total?) = 92

I called and was told that the reference range on the Anti tTG IgA is: less than 19=negative.

Based on that information, it doesn't seem likely that my daughter has Celiac, correct? I understand that only a biopsy can completely rule it out, but that number makes it unlikely, doesn't it?

Unfortunately, without knowing the reference ranges for the total IgA, you won't have a true picture of whether or not she is IgA deficient. If she is, the TtG IgA will not be accurate. In such a case, the doctor would have to rely on an IgG version of the TtG antibodies.

We can't say for sure if she has it or not (we are definitely not doctors). It is definitely possible to have celiac, but have a false negative bloodwork result. This becomes even more likely when the villi damage is less severe.

      Thank you for the information ill will definitely bring it into practice .

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. 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. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.

      Welcome to the community! Generally, for a gluten challenge before celiac disease blood tests, Tylenol (acetaminophen) is considered safe and should not interfere with your antibody results. The medications you typically need to avoid are those like ibuprofen (Advil, Motrin) or naproxen (Aleve) that can cause intestinal irritation, which could potentially complicate the interpretation of an endoscopy if you were to have one. However, it is absolutely crucial that you confirm this with either your gastroenterologist or your surgeon before your procedure. They know the specifics of your case and can give you the definitive green light, ensuring your surgery is comfortable and your celiac testing remains accurate. Best of luck with your surgery tomorrow

      Thank you for the advice. I’ve actually never checked for nutritional deficiencies, but for as long as I can remember, I’ve always taken vitamin and mineral supplements — otherwise my symptoms get worse. This week I stopped eating gluten to confirm whether my symptoms are really caused by it. Starting next week, I’ll reintroduce gluten — it’s sad to go back to how I was before — but at least I’ll be able to take the necessary tests properly. I think the diagnostic process will be long, but at least I’m happy that I finally decided to address this doubt I’ve had for years.
