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.

      New labs are now very elevated

      Hello, I was very stick, with flu like symptoms, but my virus panel came back negative and we couldn’t figure out what’s going on. The doctor then added a celiac panel.

      Is Cracker Barrel`s gluten-free menu safe for kids with celiac disease?

      This kind of question is always difficult to give a definitive answer to because of so many variables. One such variable is the sensitivity of the individual celiac to small amounts of gluten cross contamination. An amount that causes a reaction in one celiac many not in another, or at least not be discernable which, of course, does not exactly equate to...

      I see that Cracker Barrel restaurants have a gluten free menu (not all locations, but one confirmed that they do). I was wondering if it is safe for my 5 year old son with celiac disease?
