Low Iga?
0

4 posts in this topic

About a month and a half ago I was told by my GP that my celiac panel was "negative." Since then I have gone gluten free anyway and my gas/abdominal pain/constipation issues have generally been getting better.

Today I asked about the test result in a follow up appointment with a gastroenterologist. He told me that while he doesn't think I have celiac (because I don't have D), technically my test result was ambiguous because my overall IgA is "slightly low".

What does having low IgA signify? Is having low IgA in itself an indicator for celiac? Or does it simply mean, as the doctor suggested, that it may just raise some ambiguity about an otherwise negative panel?

(Fortunately the doctor offered to do an endoscopy just to make sure and I am taking him up on the offer.)

A low IGA can result in a false negative. Have you tried the diet? There can be false negatives with the endoscopy also if the do not biopsy the right place in your 22 feet of small intestine. The truest test is your response to a strict gluten free diet that has been followed for a couple months. If you have any doubt at that point you could do a gluten challenge, that would tell you.

You could also choose Enterolab testing, many have been very pleased with them and much less trauma to your body.

I'm considering asking to be tested for my overall IGA because I tested negative through blood test and barely positive via Enterolab, but my symptoms where horrible. I asked the NP that ordered the test and she said some people just have low IGA and the level has nothing to do with severity since some produce more and other less. I worry that other family members could have the same problem and would also affect their test results. It will be interesting to see if others have had this problem as well.

I thought that total IgA was part of every celiac panel? In any event, you could still try getting an endoscopy to biopsy for celiac. Apparently the low total IgA does not affect a biopsy, which will show the celiac damage (if any) regardless of whether one's IgA level is low. All the low IgA does is reduce the amount of celiac-specific antibodies one would normally expect to find in the bloodwork if there was celiac damage. That's my layperson's understanding, at least.

Hopefully more knowledgeable low IgA folks will correct me if I'm wrong.

    • celiac disease is psychosomatic
      I received the amended records in the mail. I don' think the doctor even read my email with the amendment request since she only corrected one statement I never said...the statement I gave as example while briefly talking to her on the phone the other day. So, I called the office to inquire why the other statements I never said were not corrected. Fortunately, the other staff member answered the phone. I'm surprised she told me this, but it was the best therapy for me so maybe she was meant to say it! She told me she knows what I mean about that one worker because she has to deal with it, too! She said a new office manager starts next week and she gave me her direct emal address to complain about that worker. 
    • Received Results. Looks like not Celiac?
      You've all been so helpful in guiding me what to do.  I did just receive my blood work and have an appt. with my doctor next week.  I wanted her to check it because I have lived a life of being extremely exhausted, migraines/headaches, and anxiety.  My thyroid is balanced and I am healthy (other blood results that were off were low platelet, low protein, high A/G ratio).  I am not good at reading results, but it appears negative to celiac, maybe next steps are trying a gluten-free diet for sensitivity? Deamidated Gliadin Abs, IgA 2 units 0 - 19 units Negative 0 - 19

    • healthy bread recipe?
      Hello, This is my first post. My 12yr old daughter was diagnosed with ?celiac disease. Her blood test was positive, genetic screen positive and her biopsy abnormal but they are not ready to say she is celiac because her villi are damaged but not gone. We are to adhere to a strict gluten-free diet for 6 months. So far (1 month) we have adjusted well. I am learning to bake again using many many many different flours lol. However I cannot find a good sandwich bread. There are good tasting breads with little or no fiber or heavy dense breads that don't make good sandwiches or toast. She has become very constipated on this gluten-free diet because of the low fiber content of the cereal,rice and breads. We were told no oats for the first year? and no or little dairy for the first month. She has been on a low histamine diet for 4 months now as well. My question is what is the best way to make gluten free bread, oven or bread maker? Does anyone have a good healthy recipe for sandwich bread that a kid would like? We normally eat a soft 5 grain bread before gluten-free. Thank you!
    • A good diet for avoiding type 2 diabetes
      Thanks so much, gluten-free,  in my hypchondriacal panic I saw that website!  It is good to have an endorsement from a celiac.   I remember seeing quite a few reassuring stories in it along the lines that you describe. Funny isn't as because I now feel far less inclined to eat large amounts of carbohydrate now I have cut back a bit.   It seems the more sugar I ate, the more I wanted to eat.

      Hello cycling lady, have you noticed my picture is showing up as you?  Have no idea why but it's rather disconcerting to see my picture and your words 😉  Do you know how to fix it?  You seem to have far more experience with this board than I do

      Hi There, I don't know if there is a place for videos in the forum. I just watched "The Truth About Gluten" I think it is a good video. I would like to share it somewhere but don't know where it should go. Any help would be greatly appreciated.
      Here is the link if you have never watched it.
