IgA Deficiency?

I am in the process of getting tested for celiac and received my Immunoglobulin A blood test results back through my online chart.  I have not spoken with my doctor yet.  Those results are:

 

Immunoglobulin A 79 mg/dL, standard range 100 - 490 mg/dL

 

This is the second IgA test that came back slightly under the standard range.  Does this mean I am IgA deficient?

I am not a doctor, it yes, it appears that you are IGA deficient.  In terms of diagnosing celiac disease, that means that the IGA celiac tests that were run would be invalid.   Your doctor would need to run the IGG versions (hopefully he ran them all or you have to go back in for another draw).  So, if you get a negative on the celiac IGA tests   (TTg and DGP), you could still have celiac disease.

Ditto.  That's a low IgA, more commonly found among celiacs, so make sure the doctor uses IgG basaed tests (DGP IgG, tTG IgG, EMA IgG, and maybe the older AGA IgG.

Best wishes.

Thank you for the replies.  My doctor did run a full panel,  but wasn't expecting anything stellar since I have been gluten free since July.  She is waiting to get the genetic testing results back before we take the next step in testing,  possibly a gluten challenge. I have full faith in her, as she is at the University of Chicago Celiac Center.

I am very new to this and still learning.  I wasn't sure if the result had to be a certain amount below the standard range to be considered iga deficient.

You are in good hands at the University of Chicago!

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

      By Scott Adams · Posted

      Clearly from what you've said the info on Dailymed is much more up to date than the other site, which hasn't been updated since 2017. The fact that some companies might be repackaging drugs does not mean the info on the ingredients is not correct.

      Waiting Gastroenterology review

      To evaluate the TTG antibody result we’d need to know the normal range for that lab.  Labs don’t all use the same units.  However, based on any normal ranges that I’ve seen and the listed result being greater than a number rather than a specific number, I’d say yes, that is high! Higher than the range where the test can give a quantitative result. You got good advice not to change your diet yet.  If you went gluten free your intestines would start to heal, confusing any further testing,

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

      By Bev in Milw · Posted

      Scott is correct….Thank you for catching that!      Direct link for info  of fillers.    http://www.glutenfreedrugs.com/Excipients.htm Link is on 2nd page  of www.glutenfreedrugs.com   Site was started by a pharmacist (or 2) maybe 15-20 yrs ago with LAST updated in  2017.  This makes it’s Drug List so old that it’s no longer relevant. Companies & contacts, along with suppliers &  sources would need to be referenced, same amount effort  as starting with current data on DailyMed      That being said, Excipient List is still be relevant since major changes to product labeling occurred prior ’17.           List is the dictionary that sources the ‘foreign-to-us’ terms used on pharmaceutical labels, terms we need to rule out gluten.    Note on DailyMed INFO— When you look for a specific drug on DailyMed, notice that nearly all of companies (brands/labels) are flagged as a ‘Repackager’… This would seem to suggest the actual ‘pills’ are being mass produced by a limited number of wholesaler suppliers (esp for older meds out of  patent protection.).      If so, multiple repackager-get  bulk shipments  from same supplier will all  be selling identical meds —same formula/fillers. Others repackager-could be switching suppliers  frequently based on cost, or runs both gluten-free & non- items on same lines.  No way to know  without contacting company.     While some I know have  searched pharmacies chasing a specific brand, long-term  solution is to find (or teach) pharmacy staff who’s willing help.    When I got 1st Rx ~8 years ago, I went to Walgreens & said I needed gluten-free.  Walked  out when pharmacist said  ‘How am I supposed  to know…’  (ar least he as honest… ). Walmart pharmacists down the block were ‘No problem!’—Once, they wouldn’t release my Rx, still waiting on gluten-free status from a new supplier. Re: Timeliness of DailyMed info?   A serendipitous conversation with cousin in Mi was unexpectedly reassuring.  She works in office of Perrigo, major products of OTC meds (was 1st to add gluten-free labels).  I TOTALLY lucked out when I asked about her job: “TODAY I trained a new full-time employee to make entries to Daily Med.’  Task had grown to hours a day, time she needed for tasks that couldn’t be delegated….We can only hope majorities of companies are as  conscientious!   For the Newbies…. SOLE  purpose of  fillers (possible gluten) in meds is to  hold the active ingredients together in a doseable form.  Drugs  given by injection or as IV are always gluten-free!  (Sometimes drs can do antibiotics w/ one-time injection rather than 7-10 days of  pills .) Liquid meds (typically for kids)—still read labels, but  could be an a simpler option for some products…

      Food Allergies

      By Ginger38 · Posted

      So I recently had allergy testing for IGE antibodies in response to foods. My test results came back positive to corn, white potatoes, egg whites. Tomatoes, almonds and peanuts to name a few.  I have had obvious reactions to a few of these - particularly tomatoes and corn- both GI issues. I don’t really understand all this allergy versus celiac stuff. If the food allergies are mild do I have to avoid these foods entirely? I don’t know what I will eat if I can’t  have corn based gluten free products

      7yo struggling!

      By JForman · Posted

      We have four children (7-14 yo), and our 7 year old was diagnosed with NCGS (though all Celiac labs were positive, her scope at 4 years old was negative so docs in the US won't call it celiac). We have started her on a Gluten Free diet after 3 years of major digestive issues and ruling out just about everything under the sun. Our home and kitchen and myself are all gluten-free. But I have not asked my husband/her dad or her other siblings to go completely gluten-free with us. They are at home, but not out of the home. This has led to situations when we are eating out where she has to consistently see others eating things she can't have and she has begun to say "Well, I can't have <fill in the blank>...stupid gluten."  How have you supported your gluten-free kiddos in the mental health space of this journey, especially young ones like her. I know it's hard for me as an adult sometimes to miss out, so I can't imagine being 7 and dealing with it! Any tips or ideas to help with this?
