Question About Iga

6 posts in this topic

Hi-

My son was diagnosed last Septmeber with Celiac Disease. Since I also have issues with food, I am trying to determine whether I may also have a gluten intolerance.

I discussed it with my doctor who seemed to not have a lot of knowledge about the subject. I asked for the gluten IgA antibody test. The nurses in the office never had to write up that blood test before and they called the lab directly and asked what test it was and filled out a slip for me to take to them.

I had the test done and am waiting for results. My problem is, I have very little confidence that anyone knows what they are doing. I wonder if they did the right test, and I wonder if my doctor will understand the results. I called up and wanted the nurse to give me the antibody level over the phone, but she said she can't. The doctor would let me know if anything was "wrong" when he calls later.

Is there an exact name for the blood test I need? And can anyone tell me the proper number that I, an an adult female, should be over or under to consider myself either tolerant or intolerant? Thanks. I think it shouldn't be over 30, but I'm not sure. If it shows that I am intolerant, I am just going to go gluten free regardless. So I don't know if I need to go ahead with an endoscopy. I won't be eating it anymore anyway.

If it's the EMA IgA, it will only read positive or negative (with no numbers). They probably ran the Antigliadin IgA. For that test, normal levels are less than 18. For the tTG IgA, normal levels are less than 13, but I suspect it'll be the antigliadin :)

Now, one positive test isn't enough to diagnose you completely or completely dismiss celiac. It's helpful also to do the Antigliadin IgG.

This table explains whether you should suspect celiac disease or not, based on which tests are positive or negative.

EMA IgA/AGA IgA/AGA IgG/Interpretation

+ + + celiac disease 99% Probable

+ - + celiac disease probable

+ + - celiac disease probable

+ - - celiac disease probable

- + + celiac disease less likely

- - + celiac disease less likely

- + - celiac disease less likely

- - - celiac disease very unlikely

Hi-

Well, I have my results, only, they are not plus's or minus's like the chart above.

My IGA is 6, my IGG is 15. What does that sound like?

My doctor will not likely run any further tests because in his opinion, these blood tests are negative. If I do the entero lab, do I need to eat large amounts of gluten first, or can I take it anytime? Thanks.

The results don't come in plus and minus' like above. He was using that to interpret the resulsts. The + means a positive and the - means negative and then they are color coded with IgA, IgG, etc. To me the levels don't seem high.. I think they are in the normal range but I am not sure about that one. Did they test you for tTG? There are certain tests that are more specific for celiac then others.

Both are within normal range. Did he do an EMA IgA or just the antigliadin. If the EMA came back positive (it only comes back pos. or neg.), then celiac disease is probable. Otherwise, it is very unlikely that you have celiac.

The + and - symbols said that if you have a positive result in this and a positive result in that, then...it's very likely, unlikely, etc. For actual normal ranges, the Antigliadin IgA is less than 18 (you're 6) and for the Antigliadin IgG, it's less than 24 (you're 15). You tested negative in both. So, if you look at the color-coded thing I had in an above post, you'd see that a positive EMA IgA would mean that you're probably celiac...if the EMA was negative, it's extremely unlikely that you have celiac disease.

Oh, Kaiti was right. They do come in numbers, not as positive or negative. The only test that comes back as + or - is the EMA IgA

Yeah the one says positive or negative right on the results but the others come in numbers. celiac3270 is right it is very unlikely if EMA came back negative along with your other ones then you probably do not have it. One thing about just the IgA anti-gliadan is that many celiacs can be IgA deficient so you should get the EMA done and other tests done specifically for celiac :D

    • Hi everyone, I've been reading this forum sporadically and have some questions of my own. I'm in my 40s and was diagnosed with celiac last December by biopsy and blood work after months of tests by my primary and then a gastro. My husband, around the same age as me, was dx'd with stage 4 cancer a month later, so admittedly it's took me longer than I'd have liked to learn about celiac. Now I feel pretty on top of my diet. I mostly make my own food - proteins and veggies, with some certified gluten-free snacks in the mix - and am pretty strict about what I will/won't eat at friend's houses or in restaurants (I prefer to go to dedicated gluten-free kitchens whenever possible). I'm doing okay on the diet, but still getting glutened every so often, usually when I let me guard down outside the home. I also periodically see my primary and a naturopath (who happens to have celiac!), but still, I have many questions if anyone would care to answer:

      -FATIGUE. I'm still so tired, fatigued so much of the time. My doctors blame this on the stress of my husband's diagnosis and my periodic trouble sleeping. But even during weeks where I'm sleeping enough (8-10 hrs a day), eating right, exercising as I can, trying to keep stress at bay, I'm still so bleeping tired. Maybe not when I wake up, but by late afternoon. Often my legs even feel weak/wooden. Has anyone else experienced greater fatigue early on after being diagnosed? This will pass, yes? I know I could cut out the sweets and that could help, but also, being a caregiver is hard and sometimes it's nice to eat your feelings between therapy sessions.  

      -SYMPTOMS CAUSED BY FATIGUE? Sometimes I'll have other "feels like I've been glutened" symptoms if I haven't gotten enough sleep, though I'm trying so hard to sleep at least 8 hours a night these days. Hasn't happened in a while thankfully, but there was a point this summer where my insomnia was bad and my arms were achy and I had some crazy flank/back pain I'd never experienced before. For weeks. Doctor ordered me to sleep sleep sleep, taking Benedryl if needed. I did, and the symptoms went away, but weird, yes? Has this happened to you? I ask because I want to make sure I'm getting all strange pains tested to the full extent if there's a chance it's something other than celiac. I do sometimes still feel that strange side stitch after a CC incident.

      -SKIN PROBLEMS. I have had a smidge of eczema since I was a teen and it - and the dermatitis herpetiformis I've acquired with my dx - are out of control right now. I recognize the connection with stress, but also, has anyone found any great natural remedies for DH to stop the itching? I've tried so many useless ointments and medicated creams, a number of them given to my by a dermo months ago. I see my naturopath this week, but thought I'd ask here too.

      -MOSTLY gluten-free KITCHEN GOOD ENOUGH? My husband is supportive of my diet and mostly eats gluten free meals with me, but we still keep a gluten-y toaster for him and the gluten-y dog food in a corner of the kitchen and he still makes the occasional meal with gluten for himself on his own cookware (ravioli, pizza, mac n cheese, etc). Or sometimes I make eggs/toast and the like for him when he's too sick to move. Otherwise, we're militant about how we cook, which cookware we use, etc. He even has a kitchen nook off our den where he makes sandwiches. But sometimes I wonder if having two separate sponges in our shared-ish main kitchen is enough and I should just banish all gluten whatsoever from the kitchen. I can't be the only one with a mixed kitchen, right? How do you do it if you have a mixed-eating family?

      Thank you so much!  
    • Hang in there!  Count your blessings.  Do something you like to do and relax. I know that is hard to do as a young mother (as I sit here in the kitchen sipping coffee quietly as my teenager is sleeping in after a late football game last night where she marched in 90 degree plus weather in full uniform).   But seriously, take a few minutes to relax!  
    • Meredith, this is very true. A colonoscopy is for diagnosis of the lower intestine, endoscopy for the upper intestine.  How did your doctor interpret the tests? I suggest you read the link Cycling Lady gave you because it contains a lot of good information. 
    • Sorry, but this product (supplement) is not even certified gluten free.   Seems odd that a product geared to Non-Celiac Gluten Intolerance would not take the extra step of getting certified.   I guess I am a Nervous Nellie, especially after the reports that several probiotics were contaminated with gluten.   https://celiac.org/blog/2015/06/probiotics-your-friend-or-foe/
    • Thank you for posting that. I've had a lot of that bloodwork done and everything is normal. At the peak of this belly bug I had blood work done and my white count was fine. I think it's just my health anxiety scaring me into thinking this is something scarier (to me) than celiac. Maybe the anxiety will subside once I go gluten-free. The anxiety is brutal.
