Iga Serum Levels Question

Hi all! I have a quick question. My test results were of 3 things, the first 2, I forget what it was, I passed those, the numbers had to be say <3 or whatever, but I had a question about the IGA Serum values.

My value was 84 and it said passing was 81-300something.

My daughter has Celiac with the DQ2 gene. Do you think this means I am home free and DO NOT have Celiac or do you think that b/c I eat mostly gluten free (not totally) my number was passing but barely?

I'd say I eat 75-80% gluten-free. I eat what she eats naturally, but if we eat out I don't sweat the ingredients I have a sandwich here or there. I'm definetly NOT 100% gluten-free....so would eating 75% gluten-free effect my score?

I guess what I'm wondering is can I rest assured I don't have Celiac at the moment with a score of 84, or is that so borderline you'd check again?

IGA Serum 84 81-469 mg/dL is normal

Gliadin AB (IGA)<3 normal <11

TTA IGA <3 normal <5

Those are my numbers.

While you are in range for your total IgA serum, it is on the very low end of normal. So, theoretically, this could affect the outcome of the IgA based tests, that and the fact that you are pretty gluten light. Have you ever tried a 100% gluten-free trial and challenge to see if you react to gluten? That would be a pretty definite way to give you an answer. You could also request to have the IgG version of the celiac panel done, which is a good diagnostic tool for those with low IgA.

this could affect the outcome of the IgA based tests

How does the low serum affect the outcome of the IgA based tests? Sorry, I am so clueless!!

Here's the thing, I DO react to gluten now. I NEVER did before I started eating gluten-free for my daughter. Now my system cannot tolerate gluten heavy things - like beer. Oh geez, that kills me! Or regular pasta, sits in my stomach for days now I swear and/or I'll get the runs. Not for days on end like my daughter, just instead, um, sorry for TMI!

So yes, I do find gluten bothers me now. Would it bother anyone if they went mostly gluten-free and then went back to it or only gluten sensitive individuals?

THanks so much, I really don't understand the results. My daughter was SO clear cut that there was no question whatsover so we never had any interpretation issues. I also thought wow, I passed but wow, that is a really low number! What would happen if I WAS eating all gluten instead of mostly gluten-free?

Ok, so I googled it to try and understand. From what I read if your IgA SERUM levels are low, this can INACCURATELY make you pass your other levels. Is that what you were saying?

So if my number was 84 eating 80% gluten-free, can I assume it would be lower if I was eating more gluten? I KNOW I don't eat the equivalent of 4 pieces of bread a day! Many days I eat no gluten at all. Some days, maybe once a week I eat that much, but most days not even close.

Yes, you have it correct. If your total IgA serum is low, then because the celiac panel is IgA based, the results are going to be incorrect. With yours being so borderline, it's hard to say for sure that is what happened, but there's a fairly good chance. So, if you want to be retested, then ask your doc to run the IgG versions. They exist, but are not routine for most docs. in fact, my son's ped had to go get the book of blood tests because he didn't think I was right when I requested those also be done w/ his panel.

I don't think that the amount of gluten you eat would affect your total IgA. IgA is a part of your immune system and is involved in other immune functions. I think you either make it or you don't.

      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.

      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.
