What Constitutes An Iga "deficiency"?

[DChelleD]

My bloodwork showed my total IgA at 67 range is 81-463

Allergist said my IgA was low but clinically insignificant. I did not get to talk to him directly and don't plan on any further visits with him.

I just want to know what constitutes an IgA "deficiency"? My number is low but does it have to be low to a certain point to be considered a deficiency rather than just low? Or, is anything below range considered a deficiency?

Will a gluten-free or gluten-light diet affect the total IgA bloodwork?

There have been several postings about that here before, and even a low-normal total IgA can skew the IgA based celiac tests they said here.

 

I do not know about the last question.

You have an IgA deficiency. You do not have a normal amount of IgA, and they (usually) base lab's normal ranges on what 95% of the population has, so you are in the minority. Below the range is usually considered deficient, although there are varying degrees of that.

 

Your diet will not affect your total serum IgA, but a gluten lite or gluten-free diet COULD POTENTIALLY affect any celiac tests that use IgA (like DGP IgA , tTG IgA, EMA IgA, AGA IgA). The longer you are gluten-free, the more likely it becomes that your diet will affect your celiac test results.
