Celiac Tests

Hi, I'm new to this board, but not completely new to living gluten-free. Several years ago I tested positive for gluten intolerance during some routine allergy testing. However, when I was tested for celiac disease (blood tests and endoscopy), the results were negative. I went on a gluten-free diet anyway, because I felt better without gluten. But because I wasn't celiac, I wasn't always careful. Whenever I would cheat a little bit, I didn't feel that bad. But if I started eating wheat everyday, I would get sick again (digestive problems, headaches, fatigue). So I was fairly careful but not strict. For the past year, I've had terrible digestive problems. When they started I realized that a couple of foods I was eating regularly had hidden gluten in them. I tried to be stricter with my diet, and I would get better than get worse again. Sometimes getting worse was directly traceable to eating some hidden gluten. Since there are more accurate tests now than there were when I was first tested for celiac, the doctor tested me again. However, he told me I didn't need to do a gluten challenge. Again I tested negative for celiac. Now I'm wondering if the fact that I was essentially gluten-free at the time of the test may have affected the results. I suppose I should just be as strict as possible about gluten and not worry about diagnosis, but I really would like some closure on the issue.

So how accurate can the test be if you're gluten-free at the time? Do people test negative sometimes for years than eventually test positive? Should I just give up on finding the answer and maintain a strict gluten-free diet?

Sorry this is long--I appreciate your feedback!!

yes you have to be have it in your system to get proper diag.

Also make sure they run the tTG test that mayo clinic recommends.

Yep, it seems that my doc didn't quite do this right. The day that he gave me the order for the tests, he said just to go ahead and have them done that day. I knew I hadn't had any gluten for quite some time, but he said it wouldn't matter. And the two tests were fairly expensive, even after my insurance kicked in their portion. This is so frustrating! I guess I either have to have the tests done again, or I just have to go forward not knowing whether I have celiac disease or not.

In fact our small intestine heals rather quickly after going gluten-free. I read an article on this site suggesting that in order to receive an accurate diagnosis, one must be eating foods with gluten for 3-6 months prior to biopsy. That sounds like such a long time though!

      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.

      Blood results

      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
