Probable Cd? Many Questions

3 posts in this topic

Hello, This is my first post. I'm glad to find this place, although I am not yet officially diagnosed.

My doctor recently sent me for a number of blood tests, some of which related to celiac disease. I picked up the results at the lab, but don't have a follow up with doc for several weeks.

After looking at the results, I gleaned that I might have celiac disease and so have started looking around the web for more info.

Here are the test results that I'm wondering about:

Gliadin AB IGG - 11 (ref: 0-19)

Gliadin AB IGA - 98 (ref: 0-19)

Am I correct in assuming that the positive IGA means I likely have celiac disease?

I really don't have obvious GI symptoms....but I do have another autoimmune disorder (Hashimoto's thyroiditis) as well as osteoporosis and probably fibromyalgia.

Is it always necessary to have to have a biopsy? If I'm correctly understanding what I've read, it seems that the positive IGA is a pretty big clue. I'm perfectly willing to proceed with gluten-free lifestyle without a biopsy....but perhaps there are compelling reasons to have one anyway.....Can anyone clarify that for me?

Also, should I continue eating as always till I get a chance to discuss with my doc and/or have biopsy? If I'm likely to have celiac disease, I am inclined to jump right in and begin eating gluten-free to get on the road to healing. But (back to the biopsy question) maybe getting started now would mess up possible future tests.

Out of curiousity, I dipped my toe in the gluten-free lifestyle for the past two days, and am a bit concerned to find that I feel worse, if anything. Very achy!

Well, those are my questions for the moment! I'm grateful for any insight any seasoned readers might offer! Best, Geri

Hi Geri,

The Gliadin AB tests are not totally specific to celiac disease. This means that although the high IgA reading could point to celiac disease, it doesn't necessarily. You should stay on a normal diet though, since the biopsy is the next step. Do not let the doctor tell you that going gluten free before the biopsy will not mess up your test results, it WILL mess up the results. So if a biopsy is going to be scheduled stay on gluten until after the biopsy is done.

That said, I would like to welcome you to this board. There is a lot of support here, and we are always glad to welcome new members.

As for the little bit of gluten free you have tried, it often takes weeks and sometimes months to start feeling real relief from symptoms, so a few days does not really give you a good idea of how you will respond to the diet.

God bless,

Mariann :)

Hi Mariann, Thank you for the reply and the kind welcome! I'm just getting my hands around how big a topic this is and how much I have to learn. Aren't we lucky to live in a time when so much info is available! Best, Geri

    • pablito, here is the full serum (blood) panel. Make sure your doc runs ALL of the tests on it, not just 1 or 2. Insist!!!!! YOU are in charge. Remember that. Some people test negative on the most common 1 or 2 tests they run so it's always better to have the full panel run. Anti-Gliadin (AGA) IgA
      Anti-Gliadin (AGA) IgG
      Anti-Endomysial (EMA) IgA
      Anti-Tissue Transglutaminase (tTG) IgA
      Deamidated Gliadin Peptide (DGP) IgA and IgG
      Total Serum IgA   
      Also can be termed this way: Endomysial Antibody IgA
      Tissue Transglutaminase IgA 
      GLIADIN IgG
      GLIADIN IgA
      Total Serum IgA 
      Deamidated Gliadin Peptide (DGP) IgA and IgG Remember that celiac disease is a genetically inherited disease so it's important for you to find out if you have it and if so, then your kids & all first degree relatives (siblings, parents) need to be tested every 2 years in the absence of symptoms but right away if symptoms present. Do not go gluten free after the blood work as if you get positive blood work, you will need an endoscopy which you'll need to continue eating gluten for. The pimple things may or may not be the celiac rash as there are many skin problems associated with celiacs.
    • Hi, I've been experiencing on and off left side abd pain and bloating for about 3-4 years (doctors in the past didn't help much, just said I have IBS). My new doctor did some blood work and found out  my vitamin D was low, CRP was high.  Antigiladin Igg was a weak positive. I had an endoscopy done and the doctor confirmed I don't have Celiac, but she found very small ulcers (took Pepcid for 2 weeks). She also told me I have a leaky gut and non celiac gluten sensitivity. I'm taking probiotics for the leaky gut.  So for the past 3 months I've been eating gluten free and the pain came back 2 times.  The pain is always on the left side of my abdomen. Makes me feel weak, starts with constipation and usually ends with diarrhea. Tylenol helps the pain.  I'm waiting on my food allergy tests results to see if it can be anything other than gluten. So my question is, what does a weak positive Antigiladin IGG mean if a gluten free diet is not helping?  Could the "leaky gut" cause my Antigiladin IGG to rise? Really confused here, just want to start feeling better and not have the pain come back ever again.     Thanks
    • Thank you very much for the reply and advice I assume doctors didn't know or check into this disease too much back in the early 80's or my family doctor would have easily seen these symptoms and discussed this with me then. If I do have this disease it would explain a lot about my health and overall physical discomfort all my life. Pretty sad if it is the case and it could have been prevented but thankful I know about it now. I have made an apt with my doctor so shouldn't be long before I know for sure. Thanks again for your help
    • I continue to do more research but only found 3 journal articles which discuss the reversal of the fold pattern, possibly why I can't find answers I was waiting on on my latest celiac panel to come back so here it is, expecting slight cross contamination from eating out and possible several recent dentist visits. All three tests are based on a normal scale of 0-20 being within range.  DPG IgA - 24.5 DPG IgG – 6.84 tTg IgA – 22
