Are These Blood Tests Sufficient?

I posted a while ago asking what blood tests to take for Celiacs.

This is the response I got.

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

I found these tests on a lab website. Do these cover all of the tests listed above?

Celiac Disease Comprehensive AB Profile

Fasting Required: No

Specimen: Blood

Results: 4-5 Business days

Tests Included:

Endomysial Antibody, IgA - More sensitive and specific than gliadin antibodies for diagnosis of celiac disease.

Tissue Transglutaminase Antibody (tTG), IgA/IgG - A screening test commonly used when an individual is in a risk group for celiac disease, whether or not he/she has symptoms.

Immunoglobulin A, quantative - One of the most common antibodies in the body. It's used to evaluate autoimmune conditions, such as rheumatoid arthritis, lupus, and celiac disease.

Deamidated Gliadin Antibody IgA/IgG - By measuring the levels of both IgA and IgG gliadin antibodies, doctors can assess the immune system's response to gluten.

It seems like the definition of comprehensive Celiacs testing varies between labs.

Does anyone know of any online labs I can go to that will provide all those tests without a doctor's prescription?

I do not any doctors visits available next year. I need them for other reasons.

Here is one I found during a recent search -- it has a website...but utilizes many physical labs throughout the country:

Thank you.

The way I am reading it, the tests on that website do not include the following:

Anti-Gliadin (AGA) IgA

Anti-Gliadin (AGA) IgG

Are those essential?

Of the Gliadin tests - the Demiated Gliadin Peptide is newer and preferable to the AGA.

The AGA tests antibodies created in response to one of the two proteins in gluten - Gliadin

The DGP tests antibodies created in response to the peptides that the Gliadin protein breaks into during digestion.

I usually tell folks to push their docs for all the tests you listed - but the AGA is the least important of the panel.

      Supplements for those Diagnosed with Celiac Disease

      You may also need to supplement with B12 as this vitamin is also involved in iron assimilation and is often deficient in long-term undiagnosed celiac disease.

      Is it gluten?

      @par18, no, Scott's use of the term "false negative" is intentional and appropriate. The "total IGA" test is not a test used to diagnose celiac disease per se. The IGA immune spectrum response encompasses more than just celiac disease. So, "total IGA" refers to the whole pie, not just the celiac response part of it. But if the whole pie is deficient, the...

      This may be the problem. Every time you eat gluten it is like giving a booster shot to your immune system, telling it to react and produce antibodies again.

      Scott, I am mostly asymptomatic. I was diagnosed based on high antibodies, low ferritin (3) and low vitamin D (10). I wasn't able to get in for the biopsy until 3 months after the blood test came back. I was supposed to keep eating gluten during this time. Well why would I continue doing something that I know to be harmful for 3 more months to just get...

The IGA immune spectrum response encompasses more than just celiac disease. So, "total IGA" refers to the whole pie, not just the celiac response part of it. But if the whole pie is deficient, the spectrum of components making it up will likely be also, including the celiac disease response spectrum. In other words, IGA deficiency may produce a tTG-IGA score that is negative that might have been positive had there not been IGA deficiency. So, the tTG-IGA negative score may be "false", i.e, inaccurate, aka, not to be trusted.

      Scott, I am mostly asymptomatic. I was diagnosed based on high antibodies, low ferritin (3) and low vitamin D (10). I wasn't able to get in for the biopsy until 3 months after the blood test came back. I was supposed to keep eating gluten during this time. Well why would I continue doing something that I know to be harmful for 3 more months to just get this test? So I did quit gluten and had the biopsy. It was negative for celiacs. I continued gluten free with iron supps and my ferritin came back up to a reasonable, but not great level of around 30-35.  Could there be something else going on? Is there any reason why my antibodies would be high (>80) with a negative biopsy? could me intestines have healed that quickly (3 months)?  I'm having a hard time staying gluten free because I am asymptomatic and i'm wondering about that biopsy. I do have the celiacs gene, and all of the antibody tests have always come back high. I recently had them tested again. Still very high. I am gluten free mostly, but not totally. I will occasionally eat something with gluten, but try to keep to a minimum. It's really hard when the immediate consequences are nil.  with high antibodies, the gene, but a negative biopsy (after 3 months strict gluten-free), do i really have celiacs? please say no. lol. i think i know the answer.  Asa

      I have had a long year of testing unfortunately still not diagnosed , although one thing they definitely agree I'm gluten intolerant, the thing for me I have severe back troubles they wouldnt perform the tests and I couldn't have a full MRI because I'm allergic to the solution , we tryed believe me  I tryed lol , another was to have another blood test after consuming gluten but it makes me so bad I tryed it for only a week, and because I have a trapped sciatic nerve when I get bad bowels it sets that off terribly so I just take it on myself now , I eat a gluten free diet , I'm the best I've ever been , and if I slip I know it so for me i have my own diagnosis  and I act accordingly, sometimes it's not so straight forward for some of us , for the first time in years I can plan to go out , and I have been absorbing my food better , running to the toilet has become occasionally now instead of all the time , i hope you find a solution 🤗
