Low Iga

Hey Everyone,

 

Is a low IGA anything to be worried about?

I only know that low IGA will invalidate any IGA related celiac testing. Others can hopefully give you more info.

I'm told it doesn't mean a whole lot but it did explain why I seem to catch every little cold my kids bring home. 

 

"People with selective IgA deficiency are usually asymptomatic,^{Open Original Shared LinkOpen Original Shared Link} but can have increased frequency of infections, particularly in the respiratory, digestive and genitourinary systems, for example, Open Original Shared Link and Open Original Shared Link. These infections are generally mild and would not usually lead to an in-depth workup except when unusually frequent."

"How common is IgA deficiency in those with celiac disease?

2-5% of those with celiac disease are IgA-deficient, and 0.5-1% of the general population. If IgA deficient, or if there is some other equivocating factor to potentially compromise the blood test, then an Open Original Shared Link is also given."

For me, those labs are hard to read. Your IgA was a 42 and the range was 81-463? If that's right then ditto the previous posters: your low IgA will make all other IgA based celiac tests invalid. You'll need to run the IgG based tests. You should probably have more testing down as the tests they ran on you are pretty outdated. Almost no one uses the reticulin tests anymore and the AGA (anti-gliadin antibdies) tests are going the same way... out.

 

If you want more testing, ask for the:

DGP IgG (demaminated gliadin peptides)

tTG IgG (tissue transglutiminase)

EMA IgG (endomysial)

 

Then there is always the endoscopic biopsy and then a gluten-free diet to try.  

 

Best wishes.
