Positive Tissue Transglutaminase Iga Test

I am so confused. I have just been diagnosed with Celiac via the tissue transglutaminase IGA test & having symptoms for years that have gotten much worse in the past several months. I asked my Dr about doing the endoscopy biopsy for confirmation and he said it was not necessary since i tested positive high for antibodies and am having symptoms. The nutritionist also told me i didn't need biopsy. But, then other people have said biopsy is required and a lot of the websites i have been reading.... I did my first gluten free shopping trip and was all mentally set to start the diet Monday.

I just want to see what others say about biopsy and if it is really necessary at this point? I feel confused about all of this.

THANKS :)

Biopsy is NOT necessary. The only real way to tell if you have a gluten problem (when you have symptoms) is to go on a gluten free diet. For the lucky (like yourself) you can get a Dx with just bloodwork. Biopsies are often neg. because damage can be spotty. If they dont take samples from the right places, it wont show villa damage.

You are SMART and RIGHT ON to start the diet right away.

If your tTG IgA is positive, then that is conclusive for celiac as I understand it. The full panel includes other tests which are required to rule out a false negative if the tTG IgA is low because of another problem causing all IgA levels to be low.

Many doctors still want to do the biopsy which was the only tool before the current blood tests for antibodies became available.

Unless you have a specific need to have a documented diagnosis, I would skip the biopsy and just start the gluten free diet.

In some circumstances, a documented medically proven diagnosis may be useful. It may be needed to convince a school, camp, hospital, or other care facility that the need for a completely gluten free diet is genuine. One day, we hope that all doctors will accept the tTG IgA as proof. For now, many don't.

I have just been diagnosed with Celiac .. ... .

I say diagnosed is diagnosed.

Don't know your symptoms, but once gluten-free chances are, before long, you'll feel better than you have in many years.

I'm thinking if your doctor dignosed you, then that's the end of it--you have been diagnosed. I don't think anyone is going to dig deeper and see exactly how he came to that conclusion--unless I'm missing something....

You have a great doctor there. You have been diagnosed and now you can start healing. You found the right place for any guidance and support you may need.

The Celiac Sprue Association is also a good source for a starting point on the diet. I really like that they give a starting diet and an 'expanding' one for after you heal. Here is a link.

      I'd go with a vodka tonic, but that's just me😉

      That and my nutritionist also said that drinking cider is one of the worst drink choices for me, given that I have candida overgrowth.  She said the combination of the alcohol and sugar would be very likely to worsen my candida problem.  She suggested that if I drink, I go for clear vodka, either neat or with a splash of cranberry.   So in summary, I am giving ciders a rest.  Whether it's a gluten risk or sugars and yeast overgrowth, its just not worth it.

      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.
