Test For Iga Deficiency?

It's been suggested that I may be IgA deficient. Does anybody know where I can get tested for this? Ideally an online test that I can do at home and send in, but alternatively what to ask a doctor for.

Thanks. :)

The Total Serum IgA rules out IgA deficiency...what tests for celiac did you have done already?

I had enterolab's Gluten/Casein Sensitivity Stool and Gene Panel Complete. The gene test showed one celiac marker gene and one gluten sensitive gene. However, I had already gone gluten-free for 5 months prior to the test, and the antibody tests were negative. Enterolab thought this would have more to do with me maybe being IgA deficient than being gluten-free, as their stool test is supposed to be able to detect antibodies for quite a while after a gluten-free diet is introduced. Of course this varies from person to person. What's made me curious though is that that casein part also came back negative and I had been eating that all along. I have only recently (6-8 weeks ago) become casein intolerant and cut it out of my diet, and so I have just ordered a second casein test. If this is negative again I will be very suspicious that I have an IgA deficiency.

In retrospect of course I shouldn't have gone gluten-free before getting tested, but I didn't know about the implications and was just delighted to feel well again after 13 years - same story as a lot of people here I expect.

Any doc can run an IgA test - but you might want to see an infectious disease specialist. You should be aware that if you are IgA deficient, you stand a much higher chance of having celiac, but the standard blood test for celiac will likely be a false negative.

I am IgA deficient and got a false neg celiac test. I started a gluten-free diet. It was almsot a complete cure, so my docs all agreed there was little sense doing many more tests.

In terms of the IgA deficiency, I try to be careful when I get a cold so that those viral things do not turn into bacterial upper respiratory infections since my body can't fight that kind of thing well. When a cold comes, i lay on the decongestants so I don't get too much gunk hanging out in my lungs - which in an IgA deficient person is an invitation for bacterial problems. Dayquil and Nyquil are a godsend. That and I always travel with antibiotics just in case. Add the gluten-free diet to the mix and I seem to be able to function at about 95%, not too bad given that IgA deficiency and celiac aren't a good set of cards to start out with!

      Ferritin levels.  And see what your hemoglobin looks like too, that will tell you if you are anemic?  You can have 'low normal' levels that will not be flagged by blood tests.  I had 'low normal' levels, my lab reading was. c12, just over what was considered normal, but I had small benign lesion on my tongue, and sometimes a sore mouth, and a consultant maxillofacial ordered an iron infusion for me as he felt my levels were too low and if he  raised them to 40, it would help.   Because you are not feeling 100% it might be worth looking at your levels, then discussing with your doctor if they are low normal.  But I stress, don't supplement iron without your levels being monitored, too much is dangerous.

      Hi Katht -  I sympathize with your struggles in following a gluten-free diet and lifestyle. I found out that I had Celiac Disease a few months before I turned 70. I just turned 89 and it has taken me almost 20 years to attain a fairly normal intestinal  function. I also lost a lot of weight, down to 100 lb. down from about 140 lb. What Trents wrote you was very true for me. I am still elimination foods from my diet. One person suggested you keep a food diary and that is a good idea but it is probably best just to do an elimination diet. There are several ne and maybe one for celiacs. I used one for a while and started with plain rice and zucchini and then added back other foods to see if I reacted or not. That helped a great deal but what I did not realise that it would only very small amounts of some foods to cause inflammation in my intestine. Within the last few years I have stopped eating any trace amounts of hot peppers, corn and soy(mostly in supplements) and nuts, (the corn in Tylenol was giving me stomach aches and the nuts were causing foot pains). Starting an elimination diet with white rice is better than brown rice that has some natural toxins. In addition it is very important to drink sufficient plain water. You can find out how much to drink for your height and weight online. I do have difficulty drinking 48 ounces of water but just recently have found an electrolyte supplement that helps me stay well hydrated, Adding the water and electrolytes may reduce muscle cramps and gag spams you wrote about. . Also buy some anti-gluten enzyme capsules to take with meals. I use GliadinX advertised here. These are a lot of things to do at one time as they reflect my 20 years of experience. I hope you do what you can manage to do over time. Good luck and take care.
