How Do You Know If You Are Iga Deficient?

I just got my bloodwork back from my primary care dr. She said negative for celiac, much to her surprise and mine. I have read on this Forum that a person might get a false negative for celiac if they are IgA deficient. How would I know if I were IgA deficient????

Thanks for any help you can give - I have a GI appt. at the end of the week.

A total IgA test should have been performed along with the Celiac panel. Not all docs know to do this. You could call the office and find out if they did it. Also ask about IgG responses from your testing.

I am looking at my lab report. This is what it says

Gliadin Ab, Eval

Gliadin, Ab, IgA 2.4

(refence value indicates that less tahn 20 is negative)

Gliadin Ab, IgG and that came back 6.8 (again less than 20 is negative).

I don't see ANYTHING on this lab report referring to a TOTAL IgA.

You could ask them to run it, but if you're going to get scoped anyway, it probably doesn't matter.

The Celiac blood test panel should include the following:

1. Antigliadin IgA and IgG*

2. Anti-tissue Transglutaminase Antibody (tTG), IgA and/or anti-endomysial IgA (these are both more reliable than the antigliadin tests, the endomysial one is more specific to celiac disease (almost 100 per cent), but the tTG is more sensitive)

3. Total serum IgA (this is the one that rules out IgA deficiency)

I would ask for the full panel to be run whether or not you're having an endo. There can be problems with the biopsies taken not necessarily showing villi damage because the damage can be patchy.

The doc who ordered your blood work didn't order the most important tests. Make sure to take this with you to your GI appt so that the GI knows you really haven't had a complete blood workup. Hopefully, they will order the complete panel (what tallforagirl posted). I'm not sure where you are, but if they use a lab like Prometheus (I say them because that's who my GI uses) they can do a celiac panel AND a genetic panel together.

What they should order and what they do order are sometimes two completely different things.

      Celiac and allergic to common subs and adds in prepared foods

      By DAR girl · Posted

      Looking for help sourcing gluten-free products that do not contain potato or corn derived ingredients. I have other autoimmune conditions (Psoriatic Arthritis and Sjogrens) so I’m looking for prepared foods as I have fatigue and cannot devote a lot of time to baking my own treats.

      Disregarded

      By Scott Adams · Posted

      I am so sorry you're going through this. It's completely understandable to feel frustrated, stressed, and disregarded after such a long and difficult health journey. It's exhausting to constantly advocate for yourself, especially when you're dealing with so many symptoms and positive diagnoses like SIBO, while still feeling unwell. The fact that you have been diligently following the diet without relief is a clear sign that something else is going on, and your doctors should be investigating other causes or complications, not dismissing your very real suffering.

      Paying for my own Celiac screening at WalkInLab so a positive result doesn’t become part of my medical history

      By Oldturdle · Posted

      It is just so sad that health care in the United States has come to this.  Health insurance should be available to everyone, not just the healthy or the rich.  My heart goes out to you.  I would not hesitate to have the test and pay for it myself.  My big concern would be how you could keep the results truly private.  I am sure that ultimately, you could not.  A.I. is getting more and more pervasive, and all data is available somewhere.  I don't know if you could give a fake name, or pay for your test with cash.  I certainly would not disclose any positive results on a private insurance application.  As I understand it, for an official diagnosis, an MD needs to review your labs and make the call.  If you end up in the ER, or some other situation, just request a gluten free diet, and say it is because you feel better when you don't eat gluten.      Hang in there, though.  Medicare is not that far away for you, and it will remove a lot of stress from your health care concerns.  You will even be able to "come out of the closet" about being Celiac!

      Yes, I've posted a few times about two companies: Request a Test and Ulta Labs. Also, pretty much we can all request any test we want (with the possible exception of the N protein Covid test and I'm sure a couple of others) with Lab Corp (or Pixel by Lab Corp) and Quest. I much prefer Lab Corp for their professionalism, ease of service and having it together administratively, at least in DC. And just so you know, Request a Test uses Lab Corp and Quest anyway, while Ulta Labs uses only Quest. Ulta Labs is cheaper than Request a Test, but I am tired of dealing with Quest, so I don't use them so much.

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      PS - I think you meant this site, but I don't believe it has been updated in years: http://glutenfreedrugs.com/ so it is best to use: You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/
