Iga Deficient, What Tests?

Hello,

I have a friend who wants to have her son tested but he is IgA deficient (apparently she had him screened as an infant due to signs of Celiac, but he turned up IgA deficient and the doctor would do no further testing). Anyway, he's now 8 and she wants to have him re-tested. Are there tests that will work in spite of an IgA deficiency, or is biopsy the only definitive diagnostic tool?

Thanks,

Alissa

People with IgA deficiency require a different version of the antibody tests. The tTG and EMA tests have IgG versions and these tests will then be accurate for someone with IgA deficiency. IgA deficiency is diagnosed when someone has a total serum IgA test and the results are very close to zero (less than 10mg/dl).

Sounds like the doctor didn't know anything about Celiac or how to test someone who is IgA deficient. If he had called his lab they would have told him there are differenct versions.

Here's a fact sheet she can print off and take in when she goes to have her son retested.

There is also a newer test, the DGP (deamidated gliadin peptide) which has an IgG version and is very specific for celiac.

      High TTG-IgG and Normal TTG-IgA

      Thank you for the clarification and for taking the time to explain the terminology so clearly. I really appreciate your insight, especially the distinction between celiac disease and NCGS and how anemia can point more toward celiac. This was very helpful for me.

      Son's legs shaking

      Hi, My 7 year daughter has complained of this in the past, which I thought were part of her glutening symptom, but more recently I have come to figure out it's part of her histamine overload symptom. This one symptom was part of her broader profile, which included irritability, extreme hunger, confusion, post-nasal drip. You might want to look up "histamine...

      Son's legs shaking

      My 5yo was diagnosed with celiac last year by being tested after his sister was diagnosed. We are very strict on the gluten-free diet, but unsure what his reactions are as he was diagnosed without many symptoms other than low ferritin. He had a school party where his teacher made gluten-free gingerbread men. I almost said no because she made it in her...

      Not necessarily. The "Gluten Free" label means not more than 20ppm of gluten in the product which is often not enough for super sensitive celiacs. You would need to be looking for "Certified Gluten Free" (GFCO endorsed) which means no more than 10ppm of gluten. Having said that, "Gluten Free" doesn't mean that there will necessarily be more gluten than "Certified...

      Disaccharide deficient, confusing biopsy results, no blood test

      I think it is wise to seek a second opinion from a GI doc and to go on a gluten free diet in the meantime. The GI doc may look at all the evidence, including the biopsy report, and conclude you don't need anything else to reach a dx of celiac disease and so, there would be no need for a gluten challenge. But if the GI doc does want to do more testing, you...

      Hi,  My 7 year daughter has complained of this in the past, which I thought were part of her glutening symptom, but more recently I have come to figure out it's part of her histamine overload symptom. This one symptom was part of her broader profile, which included irritability, extreme hunger, confusion, post-nasal drip. You might want to look up "histamine intolerance". I wish I had known of this at the time of her diagnosis, life would have been much easier.  I hope you are able to figure out.

We are very strict on the gluten-free diet, but unsure what his reactions are as he was diagnosed without many symptoms other than low ferritin.  He had a school party where his teacher made gluten-free gingerbread men. I almost said no because she made it in her kitchen but I thought it would be ok.  Next day and for a few after his behavior is awful. Hitting, rude, disrespectful. Mainly he kept saying his legs were shaking. Is this a gluten exposure symptom that anyone else gets? Also the bad behavior?

The GI doc may look at all the evidence, including the biopsy report, and conclude you don't need anything else to reach a dx of celiac disease and so, there would be no need for a gluten challenge. But if the GI doc does want to do more testing, you can worry about the gluten challenge at that time. But between now and the time of the appointment, if your symptoms improve on a gluten free diet, that is more evidence. Just keep in mind that if a gluten challenge is called for, the bare minimum challenge length is two weeks of the daily consumption of at least 10g of gluten, which is about the amount found in 4-6 slices of wheat bread. But, I would count on giving it four weeks to be sure.
