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.

      Working in a kitchen with gluten?

      By PixieSticks · Posted

      Hi yes! I was diagnosed 10 years ago through a biopsy. I’ve been gluten free ever since but no one I’m around is gluten free. I sometimes wore a surgical mask in the kitchen. but I believe particles were still getting through. I’ll definitely look into n95 instead. thanks for the reply.

      Skinesa

      By BoiseNic · Posted

      Ya I used to react to iodine, but it doesn't bother me anymore after strict adherence to a gluten-free diet for many years now. I am happy to report that for the first time ever in my life, a probiotic formula is not making me break out, but actually seems to be helping. The strains in this formula have been specifically tested to help with skin issues. It is gluten and dairy free also.

      Feeling ill

      By knitty kitty · Posted

      @Whyz, I take a combination of Thiamin (Benfotiamin), B12 Cobalamine and Pyridoxine B6 for my pain and headaches.  Really works well without hurting the digestive tract.  Riboflavin B2 also helps with migraines.  Most newly diagnosed people have vitamin and mineral deficiencies.  Check with your doctor and nutritionist.   If you follow the updated gluten challenge guidelines, you can wait until two weeks (minimum) before your appointment, then eat lots of gluten, like six slices of gluten containing bread or "name your poison".   Here's the Updated Gluten Challenge Guidelines: Recommended intake of gluten should be increased to 10 grams of gluten per day for at least two weeks. Or longer. While three grams of gluten will begin the immune response, ten grams of gluten is needed to get antibody levels up to where they can be measured in antibody tests and changes can be seen in the small intestine.   Keep in mind that there are different amounts of gluten in different kinds of bread and gluten containing foods.  Pizza crust and breads that are thick and chewy contain more gluten than things like cake and cookies.   References: https://www.beyondceliac.org/celiac-disease/the-gluten-challenge/ And... Evaluating Responses to Gluten Challenge: A Randomized, Double-Blind, 2-Dose Gluten Challenge Trial https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7878429/?report=reader  "In our study, limited changes in Vh:celiac disease (villi height vs crypt depth - aka damage to the small intestine)  following 14-day challenge with 3 g of gluten were observed, in accordance with Sarna et al.  While the 3 g dose was sufficient to initiate an immune response, as detected by several biomarkers such as IL-2, the 10 g dose was required for enteropathy within the study time frame. Based on our data, we would suggest that gluten challenge should be conducted over longer durations and/or using doses of gluten of ≥ 3 g/day to ensure sufficient histological change can be induced." Keep us posted on your progress!

      Advantages vs. Disadvantages of having an official Celiac diagnosis

      By Scott Adams · Posted

      I don't believe that existing life insurance policies require such notifications--health checks are typically done before such policies are obtained. I believe it would primarily affect any new policy you get, and perhaps any policy renewal.

      You could go gluten-free now, and then start eating lots of gluten for at least 2 weeks before your endoscopy--just be sure to tell your doctor about this beforehand. If your symptoms go away on a gluten-free diet, it is further evidence of celiac disease and/or non-celiac gluten sensitivity.  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.
