Iga Deficiency

What exactly is IGA deficiency? Does that mean your levels are low, or that you don't have any? What causes this? I have heard this mentioned a lot.

IgA deficiency results in your levels being lower than the actually would be. This is important because while a low IgA might make you think a test to be negative for celiac, if you have IgA deficiency, then that might be what keeps it in the normal range--and in fact, you might actually HAVE celiac.

Would Iga deficiency give false low readings for the other tests?(Igg,tTg orEma?)

No...just the IgA. But an elevated IgA is also relatively common, which is why the IgA alone cannot diagnose...you also need the IgG and the EMA

Yep you need the full panel with the IgG , tTG, EMA, and IgA...IgA deficiency would not effect all of them.

    • I have 2 copies of DQ9. One from each parent.
    • Obviously from the outside it's difficult to comment, but if I were you I'd leave allergies for now and pursue definitive celiac testing via your doctor and preferably a gastroenterologist. They're the first port of call for digestion issues. If you do wind up being celiac it's possible that other allergies or intolerances would resolve or improve in any case once you've been on the diet for awhile. That's been my experience.   Ps note that wheat allergy is completely different and unrelated to celiac or non celiac gluten sensitivity. 
    • Thank you ps, it may be better if the thread title was changed as we now have two 'overwhelmed' topics. If it were 'Bile ducts and celiac?' then it may attract more users with direct experience?
    • Hello and welcome Maybe? From reading others accounts there's a big variation in how quickly gluten antibodies respond to the gluten diet. I did similar to you and my doctor said that 1 week back on should be enough to show up in a test, but he didn't know what he was talking about sadly... The 2 week figure refers to the endoscopy, for blood testing 8-12 weeks on gluten is more normal.  Basically if it comes back positive fine you have your answer. If its negative it may be a false negative due to your going gluten free beforehand. If you want to pursue a diagnosis then yes. Don't go off gluten again until you confirm that all testing is complete.  Keep a journal noting any symptoms, that may be useful to you later. More info here: There's some good info in the site faq: https://www.celiac.com/gluten-free/announcement/3-frequently-asked-questions-about-celiac-disease/ I know how you feel! Partway through my gluten challenge I knew that too results notwithstanding. Fwiw I think you've found your answer. Good luck!
    • Learn more about testing for celiac disease here: http://www.cureceliacdisease.org/screening/ You do have to be on a gluten diet for ANY of the celiac tests (blood and biopsy) to work.  While the endoscopy (with biopsies) can reveal villi damage, many other things besides celiac disease can cause villi damage too: http://www.cureceliacdisease.org/faq/what-else-can-cause-damage-to-the-small-intestine-other-than-celiac-disease/ So, both the blood test and endoscopy are usually ordered.  There are some exceptions, but those are not common.
