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.

      Desperately need a vitamin D supplement. I've reacted to most brands I've tried.

      I do not know this, but since they are labelled gluten-free, and are not really a product that could easily be contaminated when making them (there would be not flour in the air of such a facility, for example), I don't really see contamination as something to be concerned about for this type of product.

      Thanks @Scott Adams. Do you know if Kirkland Signature supplements share facility and production lines with other products containing gluten? I'm worried that I'll react to this brand just like I did with other gluten-free labelled supplement brands.

      This is a really common area of confusion. Most natural cheeses (cheddar, Swiss, mozzarella, Parmesan, brie, camembert, and most blue cheeses) are inherently gluten-free, and you’re right that the molds used today are typically grown on gluten-free media. The bigger risks tend to come from processed cheeses: shredded cheese (anti-caking agents), cheese spreads, beer-washed rinds, smoke-flavored cheeses, and anything with added seasonings or “natural flavors,” where cross-contact can happen. As for yeast, you’re also correct — yeast itself is gluten-free. The issue is the source: brewer’s yeast and yeast extracts can be derived from barley unless labeled gluten-free, while baker’s yeast is generally safe. When in doubt, sticking with whole, unprocessed cheeses and products specifically labeled gluten-free is the safest approach, especially if you’re highly sensitive.
