Does anyone have an opinion or have experience with this test. I ordered one from "great plains lab" and was not sure if this was the best type of test to use to confirm or not. I have no insurance and I am a full time student on a tight budget but I really want to find out if I do have celiac or not. I think I do but then again maybe it is something else. I am looking for the least expensive yet most reliable test I can find. If anyone has advise --Thank You

ps> I was gluten-free for about a month and had my first normal bm in about 20yrs. but I began a gluten challenge 2 days ago and no D -- yet ;) but massive bloating :o, could be gluten or the cheese on my sandwich at work today- I know for sure I'm lactose int. but a slice of cheese is usually ok

If you were gluten free for a month then that can interfere with the accuracy of tests. The tTG test is one of the most specific tests for celiac so yes that is a good test to get done. I had this test done by prometheus labs and it came back high.

It is also a good idea to have the IgA test along with the TTG test in case you are IgA deficient with celiac disease. If you are IgA deficient and have celiac disease the test can sometimes come back as a false negative.

Thanks karen and kaiti for the replies. I think I'm not going to be able to stay on the gluten challenge until the 23rd (my appt). I just don't want to go through the bloating, big D, crampy, tired and foggy way I feel :blink: . I spent the last 10++ years feeling like cr**. and it seems worse now since I had been gluten-free for over a month. Plus I don't have insurance and I start school in 3 weeks, full time in addition to a full time job. I think I would rather spend the $$ on gluten-free foods than on the tests that will tell me I need to buy gluten-free.

      Blood results

      Maybe celiac but maybe NCGS that was misdiagnosed as IBS morphing gradually into celiac. Is NCGS a new category to you? It shares many of the same GI symptoms with celiac disease but does not damage the small bowel lining like celiac.

      Oral thrush question

      By knitty kitty · Posted

      Thiamine has antifungal properties.  The body uses thiamine to keep bacteria and yeasts from overgrowth in the digestive system.   Fluconazole use can cause thiamine deficiency.   Supplementing with thiamine in the form Benfotiamine would be beneficial as Benfotiamine promotes intestinal healing.   Thiamine and the other B vitamins tend to be low in Celiac due to malabsorption.  Talk to your doctor about supplementing vitamins and minerals.

      Nutrient deficiencies despite normal MARSH and strict gluten-free diet

      By Scott Adams · Posted

      Welcome @Natalia Revelo, your experience is profoundly difficult and, sadly, not entirely unique within the celiac community. It's the frustrating reality of "silent" or ongoing damage that isn't captured by the MARSH score alone, which only measures active villous atrophy. Your normal biopsy suggests your diet is preventing the classic autoimmune attack, but it doesn't mean your gut has fully healed or that other issues aren't at play. The inflammation from your newly discovered milk and egg allergies is a huge clue; this constant allergic response can create a low-grade inflammatory environment that severely hampers nutrient absorption, effectively creating a "leaky gut" scenario independent of celiac damage. This is likely why your iron stores deplete so rapidly—your body is both unable to absorb it efficiently and may be losing it through inflammation. While the functional medicine path is expensive, it's clearly providing answers and relief that traditional gastroenterology, focused solely on the gluten-free diet and biopsy results, is missing. To move forward, continue the gut-healing protocols your functional doctor recommends (perhaps exploring alternative options to glutamine that won't irritate your cystitis), maintain your strict avoidance of all allergens and irritants, and know that true healing is a multi-faceted process. You might seek a second opinion from a different gastroenterologist who is more knowledgeable about non-responsive celiac disease and the complex interplay of food allergies and micronutrient absorption, but your current path, while costly, seems to be leading you toward the steady health you need.

      Have you had a DNA test to look for Celiac disease genes?  If she doesn't have any celiac specific genes, look for another explanation.  If she does have Celiac genes, assume they are turned on and active Celiac disease is progressing.  All first degree relatives (mother, father, siblings, children) should be genetically tested as well.   Sometimes blood tests are ambiguous or false negatives if one has anemia, diabetes or thiamine deficiency.  Certain medications like antihistamines and steroids can suppress the immune system and result in false negatives or ambiguous results on antibody tests.

      That was just the visual report, so need to wait for confirmation or otherwise from the results. They did take a biopsy from the upper end of the duodenum(D1). D2 looked unremarkable on the camera. Just wish we didn’t have to wait so long for the results as she’s naturally a very anxious person. But thanks so much for taking the time to answer me
