Total Iga Test Is High
0

10 posts in this topic

My 3 year old son's Total IgA test was high (not the IgA-gliadin). All I can find on the internet is about IgA deficiency, nothing about what it means when it's high. Anyone else know what can cause it to be high?

How high? And what were the reference ranges provided by the lab?

She said the normal range for a 3 year old is in between 20-150 and my son's was 202

The elevated Total IGA should be investigated. It may not be of a concern but it should not be blown off. Ask your ped and also consult a GI about it. If they haven't run stool testing for microbes, infectious agents etc. they most likely will.

The other part is that the IgA based tests won't be compromised (as would be the case if he were IgA deficient).

Was he fighting anything off at the time, like a cold? My son's came back slightly elevated when we had his done, and was fighting a cold at the time. It made sense that his IgA was a little high.

Just a thought...

No, actually this was one of the few times that he wasn't sick at all. It's just aggervating me that I can't find anything on what causes it to be high, everything I find is about it being too low.

I would follow up, there are a lot of causes for an elevation in the total IGA and perhaps a phone call to your peds office might help ease your mind. Express your concerns to a nurse. Your doctor may plan on just retesting in a couple of months to see if it has gone down.

I'm not sure I can shed too much light on this, but I too had elevated IgA scores and empathize with the lack of information. The normal range for my health care provider is 68-378, my scores were 511 and 484 a couple months apart. The allergist I was working with said there are several things that could cause the high IgA levels, including autoimmune disorders, kidney/GI issues (including celiac), certain infectious diseases and a few other very unusual immune related things. What he didn't mention, of course, is non-celiac gluten sensitivity. I recently did the EnteroLab testing and my anti-gliadin IgA scores were fairly high. So, in my case, the overall IgA scores could simply be a reflection of the anti-gliadin levels.

However, I'm not a three year old. And I agree with earlier posters - you should bring it up with the doctor.

Thanks everyone. We have our next gastro appointment on tuesday, hopefully we will have the other test back by then. I just have so many mixed feelings because I don't want my son to be different then everyone else but I sure would love to fix whatever the underlying cause is for him being so miserable allllll the time. I will keep everyone updated on how the other test turn out. Thanks again

    • Cyclinglady is absolutely correct, after hours of internet research the only gluten-free food available at JNB is a fast food chain called 'Nandos'. I was hoping for a bit more variety, but I'll take what I get.   
    • I'm so confused about my daughter's diagnosis.  I hope somebody can help.   My 4 year old daughter has a swollen belly, stomachaches, and lots of gas.  She does not have diarrhea or delayed growth.  Because of her symptoms and because it runs in the family (2nd degree relatives) I had her tested for celiac.   She was weak positive for TTG (IGA)  and strong positive for DGP (IGG)   TTG (IGA)  8   (0-3 neg, 4-10 weak positive, greater than 10 positive) TTG (IGG)  2   EMA: Negative DGP (IGG)  47  (0-19 negative, 20-30 weak positive, greater than 30 positive) Last week, she had her endoscopy.  The doctor found inflammation and little holes or bumps on her duodenum.  He started her on prevacid and said based on his observations, he was suspicious of celiac, but he would not be able to confirm until the biopsy came back. The biopsy showed no signs of celiac disease.  He said that he could not diagnose her with celiac without the biopsy report saying there was celiac damage.  He said he would categorize her as a potential celiac, keep her on a gluten diet and redo the endoscopy in a year or two to check for damage again.  My questions are: 1.)  If it is not celiac, something is causing her duodenum to be inflamed and have little holes or bumps on it, right?  Could it be a wheat allergy or gluten sensitivity?  What else could it be and how do they test for it?  Given her elevated celiac antibodies, how likely is it to be anything besides celiac causing the damage?  2.)  How likely are false positives for TTG and DGP?  I've heard they are pretty sensitive and specific.  Does getting two positives make false positives less likely? 3.) What have you done in this situation?  I want her to have an official diagnosis to make things easier at school and to feel confident that we are eliminating gluten permanently for a worthy reason, etc.  But, I'm having a hard time imagining keeping her on gluten and waiting for her to get more sick and have more intestinal damage just for a diagnosis.     Thanks in advance for your help.  I'm so overwhelmed and confused.  I hope someone has some insight and experience that will help clear things up for me.            
    • Yeah I actually live in Japan which is pretty similar, because Coeliac disease is rare over here so is the understanding and accommodating it. When I mention Gluten to some restaurants they think I am talking in English and they are unfamiliar with the word in Japanese.    So it seems I can write off my chances of getting some authentic Chinese gluten-free food at the airport, but at least there is a Thai restaurant in T3 so I won't starve. Its called  'Phrik Thai' for future reference. http://en-shopping.bcia.com.cn/store/739.html  
    • While in Boston I found Cheer's  Bloody Mary mix that says gluten-free on the bottle and have had no issues and  tastes pretty good 
    • I always assumed plain coffee was, but I have seen some controversy online about this. I know someone who is gluten free and only buys whole beans and grinds them herself because she doesn't trust how the grounds are processed.
