Hello,

My doctor just finished testing me and got my results via e-mail. I can not go back to him before 6 weeks for work reasons and I would like to know what these results mean:

IgA - 283.00 mg/dl

Hello,

My doctor just finished testing me and got my results via e-mail. I can not go back to him before 6 weeks for work reasons and I would like to know what these results mean:

IgA - 283.00 mg/dl

CELIAC SCREEN - 42.2 U/ml (Includes TTG and DGP)

Transglutaminase_IgA - 7.50 EU/ml (IgA isotype of TTG)

ENDOMYSIAL Ab - NEGATIVE

Vitamin D - 31.4 nmol/L

Vitamin B-12 - 482 pmol/L

Thanks.

We can't interpret any labs without the normal ranges. That looks like a normal total IgA, but if that's the case all it says is that your celiac panel would be valid.

Hello,

Thanks for responding so fast. The results plus the lab normal ranges are as follow:

IgA - 283.00 mg/dl (NORMAL IS 70 TO 500)

CELIAC SCREEN - 42.2 U/ml (Includes TTG and DGP) (NORMAL IS 0 TO 40)

Transglutaminase_IgA - 7.50 EU/ml (IgA isotype of TTG) (NORMAL IS 0 TO 20)

ENDOMYSIAL Ab - NEGATIVE (IgG+IgA iso. of endomys)

Vitamin D - 31.4 nmol/L (NORMAL IS 75 TO 250)

Vitamin B-12 - 482 pmol/L (NORMAL IS 156 TO 672)

Thanks.

Ah, that makes more sense.

You have a low positive on the celiac screen, but the other two major celiac tests (TTG and endomysial) are negative. The DGP test in the celiac screen is the most sensitive of the three tests by far, so it is reasonably common to be celiac with a positive result on only that one test. It means you have antibodies to DGP (deamidated gliadin peptide). DGP is only produced in your intestine if you either have celiac disease or are on the way to developing it. If I had your panel, I would ask my doctor for a referral to a GI for a biopsy to see what's going on. You need to keep eating gluten in order to get an accurate biopsy.

Your vitamin D is low, which isn't unusual. You can email your doctor right now and ask how much D3 he recommends. Mine was at 28 and they started me on 2,000 IU a day. You can start taking the vitamin D right away. The little liquid capsules are supposed to be better than dry pills.

Once the biopsy is over, if I were you I would go gluten-free. It's possible to have a false positive lab test but even if the biopsy doesn't turn up anything I would find the DGP worrisome as far as continuing to eat gluten.

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      Sigh. I posted this yesterday based on the Safeway website. I went back again today to their website to double check. On the page where they are selling Vanilla Bean flavor, it has a distinct Certified Gluten Free label. Other flavors on the Safeway website didn't have the gluten-free statement. Today I went into the store. None of the flavors I looked at, including Vanilla Bean, have a Gluten Free statement. Is it safe? Who knows. The ingredients are either safe or nearly safe (some have "natural flavor"). There are warnings about "contains milk and soy" but not about wheat - this implies they are safe, but again, who knows. On the other hand, every flavor I checked of their Slow Churn line of ice creams has wheat as an ingredient. 100% not safe.

      Do keep in mind that many of the newly diagnosed have lactose intolerance.  This is because the villi lining the intestinal tract are damaged, and can no longer make the enzyme lactAse which breaks down the milk sugar lactOse.  When the villi grow back (six months to two years), they can again produce the enzyme lactAse, and lactose intolerance is resolved.  However, some people (both those with and without Celiac Disease) are genetically programmed to stop producing lactase as they age.   Do be aware that many processed foods, including ice cream, use Microbial Transglutaminase, a food additive commonly called "meat glue," used to enhance texture and flavor.  This microbial transglutaminase has the same immunogenicity as tissue transglutaminase which the body produces in response to gluten in people with Celiac Disease.  Tissue Transglutaminase (tTg IgA) is measured to diagnose Celiac Disease in blood tests.  Microbial Transglutaminase acts the same as Tissue Transglutaminase, causing increased intestinal permeability and inflammation.   New findings show that microbial transglutaminase may be able to trigger Celiac Disease and other autoimmune and neurodegenerative diseases.   Microbial Transglutaminase is not required to be listed on ingredients labels as it's considered a processing aid, not an ingredient in the U.S.  Microbial Transglutaminase has been GRAS for many years, but that GRAS standing is being questioned more and more as the immunogenicity of microbial transglutaminase is being discovered. Interesting Reading:  Microbial Transglutaminase Is a Very Frequently Used Food Additive and Is a Potential Inducer of Autoimmune/Neurodegenerative Diseases https://pmc.ncbi.nlm.nih.gov/articles/PMC8537092/

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      There is a 10 year old post in this forum on Edy's and Dreyer's ice cream. The information is somewhat outdated and the thread is closed to further comment, so here is a new one. Edy's And Dreyer's Grand Vanilla Bean Ice Cream - 1.5 Quart is labeled "Gluten Free". This is a different answer than years gone by. I don't know the answer for any other flavor at this moment. On 1 May, 2026, Edy's website says: "As a general rule, the gluten in Edy's and Dreyer's® frozen dessert products is present only in the added bakery products, such as cookies, cake or brownies. We always label the eight major food allergens on our package by their common name. We recommend to always check the label for the most current information before purchasing and/or consuming a product. The exception to this rule is our Slow Churned French Silk frozen dairy dessert, which contains gluten in the natural flavors." https://www.icecream.com/us/en/brands/edys-and-dreyers/faq It seems that Edy's and Dreyer's are more celiac-friendly than they were 10 years ago. Once I found enough information to make today's buying decision, I stopped researching.

      probably not your situation @Mimiof2, but allow me to add one more to @trents list of celiac-mimics: "olmesartan-induced sprue-like enteropathy"

      Terrible Neurological Symptoms

      By knitty kitty · Posted

      My dad had an Abdominal Aortic Aneurysm.  Fortunately, it was discovered during an exam.  The doctor could feel my dad's heart beating in his stomach/abdomen.  The aneurysm burst when the doctor first touched it in surgery.  Since he was already hooked up to the bypass machine, my dad survived ten more years.  Close call! Triple A's can press on the nerves in the spinal cord causing leg pain.  I'm wondering if bowing the head might have increased the pressure on an aneurysm and then the nerves.   https://gulfcoastsurgeons.com/understanding-abdominal-aortic-aneurysm-symptoms-and-causes/ Abdominal Aortic Aneurysm Presenting as a Claudication https://pmc.ncbi.nlm.nih.gov/articles/PMC4040638/
