Ttg Positive After 1 Year Gluten Free?

Hi everyone. I need to ask the experts on this board.

I asked my doc (who I adore, by the way, and never would have been diagnosed if he had not suggested celiac) to run a celiac panel on me, as I am still having occasional *gluten* symptoms, and would like to rule out that I am still accidentally ingesting gluten. I have been gluten-free for one year.

They tested TTG (IgA, I think) and that came back positive. I think my result was 89 (it was over 200 last year). My EMA came back negative.

I thought all the tests were supposed to go negative if you're gluten-free? My doc said it just meant that I was still I celiac, and that my EMA was negative, which showed him I'm doing a good job with my diet.

What do you guys think?

Thanks!

I think that you are having problems with cross contamination.

Your doctor is not running the correct test to see if you are ingesting gluten. The tTg IgA tests for intestinal damage and other autoimmune problems can also make this elevate. This is why it is run in conjunction with the other tests in the panel. What he needs to run is the AGA IgA test, which is the anti-gliadin measurement of whether you are making antibodies to gluten from your diet. If this is positive, then you are ingesting it somewhere.

The EMA is not an indicator test of gluten ingestion and is never used to re-check levels. It is a diagnostic tool only and very specific for Celiac Disease.

Thanks for the info, very helpful. I'll check with him next time I see him. I think our labs just have one panel that they run for celiac, I'm not sure that they do the AGA IgA test. I'll find out.

I hope that I don't have another autouimmune disease going on. Maybe my intestines are just taking some time to heal.

I actually just read a study that showed that 61% of folks with diagnosed celiac disease on a gluten-free diet still had positive TTG IgA readings after one year. This number included both people who were extremely strict and those who were only mostly compliant. Let me know if you'd like me to send you the study; I know it made me feel a lot better!

Hi.

You might be having a reaction to another food. The IgA test is less common and a bit limited and needs to be done by a very experienced person. The IgG and IgE tests, when elevated, mean you are negatively reacting to a food, any food.

It is very easy to accidentally be eating gluten so recheck all your food and beverages and make sure everything is gluten-free. If it is, you might want to request a general food allergy blood test that measures both IgE and IgG against a whole list of foods.

I didn't know I had a problem wiht dairy until I had a cold and quit dairy but stayed off the gluten and after 2 weeks I ate some dairy and had what felt like a gluten reaction. Turns out it was the cheese.

Tunibell's post is interesting. I'd say cover your bases, be diligent and be patient and you will get this figured out and feeling fine in no time.

Best of luck to you~

      IBS-D vs Celiac

      What you’re describing really does not read like typical IBS-D.

      how much gluten do I need to eat before blood tests?

      oh that's interesting... it's hard to say for sure but it has *seemed* like oats might be causing me some vague issues in the past few months. It's odd that I never really connect specific symptoms to foods, it's more of an all over feeling of unwellness after eating them. If it happens a few times after eating the same foods- I cut back...

      IBS-D vs Celiac

      By Scott Adams · Posted

      What you’re describing really does not read like typical IBS-D. The dramatic, rapid normalization of stool frequency and form after removing wheat, along with improved tolerance of legumes and plant foods, is a classic pattern seen in gluten-driven disease rather than functional IBS. IBS usually worsens with fiber and beans, not improves. The fact that you carry HLA-DQ2.2 means celiac disease is absolutely possible, even if it’s less common than DQ2.5, and many people with DQ2.2 present later and are under-diagnosed. Your hesitation to reintroduce gluten is completely understandable — quality of life matters — and many people in your position choose to remain strictly gluten-free and treat it as medically necessary even without formal biopsy confirmation. If and when you’re ready, a physician can help you weigh options like limited gluten challenge, serology history, or documentation as “probable celiac.” What’s clear is that this wasn’t just random IBS — you identified the trigger, and your body has been very consistent in its response.

      oh that's interesting... it's hard to say for sure but it has *seemed* like oats might be causing me some vague issues in the past few months. It's odd that I never really connect specific symptoms to foods, it's more of an all over feeling of unwellness after  eating them.  If it happens a few times after eating the same foods- I cut back or avoid them. for this reason I avoid dairy and eggs.  So far this has worked well for me.  oh, I have some of Bob's Red Mill Mighty Tasty Hot cereal and I love it! it's hard to find but I will be looking for more.  for the next few weeks I'm going to be concentrating on whole fresh fruits and veggies and beans and nuts and seeds. I'll have to find out if grains are truly necessary in our diet. I buy brown rice pasta but only eat that maybe once a month at most. Never liked quinoa. And all the other exotic sounding grains seem to be time consuming to prepare. Something to look at later. I love beans and to me they provide the heft and calories that make me feel full for a lot longer than a big bowl of broccoli or other veggies. I can't even tolerate the plant milks right now.  I have reached out to the endo for guidance regarding calcium intake - she wants me to consume 1000mgs from food daily and I'm not able to get to more than 600mgs right now.  not supposed to use a supplement until after my next round of testing for hyperparathyroidism.   thanks again- you seem to know quite a bit about celiac.

      IBS-D vs Celiac

      By trents · Posted

      Welcome to the celiac.com community, @SilkieFairy! You could also have NCGS (Non Celiac Gluten Sensitivity) as opposed to celiac disease. They share many of the same symptoms, especially the GI ones. There is no test for NCGS. Celiac disease must first be ruled out.

      By trents · Posted

      Under the circumstances, your decision to have the testing done on day 14 sounds very reasonable. But I think by now you know for certain that you either have celiac disease or NCGS and either way you absolutely need to eliminate gluten from your diet. I don't think you have to have an official diagnosis of celiac disease to leverage gluten free service in hospitals or institutional care and I'm guessing your physician would be willing to grant you a diagnosis of gluten sensitivity (NCGS) even if your celiac testing comes up negative. Also, you need to be aware that oats (even gluten free oats) is a common cross reactor in the celiac community. Oat protein (avenin) is similar to gluten. You might want to look at some other gluten free hot  breakfast cereal alternatives.
