Pls Help Me Understand My Prometheus Blood Test Results

Hi, I'm hoping you can help me. My GI is useless and won't call me back to explain my prometheus test results to me. I finally had to have them email me the results since he wouldn't respond. The test results say the following:

Summary Interpretation: Results do not exclude a diagnosis of celiac disease

Serological markers for celiac disease not detected.

Assay Name:

Anti-Gliadin IgG ELISA (AGA IgG) < 1.2 U/ml (Range <10.0 U/ml)

Anit-Gliadin IgA ELISA (AGA IgA) 2.2 U/ml (Range <5.0 U/ml)

Anti-Human Tissue Transglutaminase IgA ELISA (TTG IgA) <1.2 U/ml (Range <4.0 U/ml)

Anti-Endomysial IgA IFA (EMA IgA) Negative (Reference Negative)

Total Serum IgA by Nephelometry (TOTAL IgA) 254 mg/dl

Alleles Detected: DQ2 heterodimer and DQ8

DQ2/DQ8 - 14X (Increased Risk Over Gen Pop) Very High (Relative Risk)

Your help in interpreting this results would be greatly appreciated.

You have the two recognized celiac genes. Although your blood tests were negative they could be a false negative, up to 20% of us will have negative blood tests. If you are planning on having a endo and biopsy stay on gluten. If your not then do give the diet a good try and see if it helps your issues.

Thanks. My first non-prometheus blood test showed an elevated anti-gliadin IGA level of 38 H so I guess it was positive. This test above was after being gluten free for about 4 months. I also had an endoscopy which the GI specialist said was negative for celiac. I don't know what to think anymore. All I know is that my neuropathy is going away after being gluten free so it must be that. Any other thoughts?

After being gluten free for 4 months, you can't run a blood test to find celiac. You have to be eating gluten for a while (3 slices of bread a day for 3 months).

So I guess that's why the prometheus was negative since I've been gluten free? I had been gluten free for about a month when I got the endoscopy so maybe that's why it also showed up negative. Anyway, at least I'm feeling better with the neuropathy so it must be the 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/

      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/
