Is genetic testing worth it

I’ve basically been told I “might” have celiac. The only clue is an endoscopy showed mild villi blunting. Serology was negative. I asked my GI doc if a genetic test would confirm a diagnosis. He was not that enthusiastic that it would. I requested the test which he granted but I just found out it costs $212 and Medicare may not cover it. As far as I know no one in my family has ever been diagnosed with celiac so I’m wondering if it will be a waste of $$. Wanted to know what folks here experience has been with the HLA  test for celiac?? I’ve been on a gluten free diet since I got diagnosed and treated for SIBO. Supposedly we knocked the SIBO but I’m still feeling rotten and celiac seems to be what we’re hanging our hat on. But as I said I’ve been on a gluten free diet for 6 months and I’m still not feeling well. So wonder if the genetic test for celiac is justified. Thanks

Over 20% of the population have the genetic markers for celiac disease, but only ~1% get it (~12% have non-celiac gluten sensitivity). Also, not all labs will test for all known genetic markers, and new ones have been found in the last few years. It's possible that you will spend the money and still be exactly where you are at now. The best hope is that they would find no markers for celiac disease, but this many not rule out NCGS.

If money isn't an issue I'd probably just do the genetic testing if I were you, but it may not give you the answer you seek.

Scott. Do I understand that a negative HLAQ8 test does not mean that I’m not gluten sensitive, but  at least it rules out celiac??? and a positive result does not guarantee I have celiac?? I just have the marker??

thanks. I interpreted the article as a negative result doesn’t necessarily mean negative especially if the lab doesn’t test for both subunits 

I should mention I had an abdominal CT recently that didn’t show anything out of the ordinary for my small bowel or colon. No dilation, lymph nodes or fluid associated with either

      Draft gluten-free ciders… can they be trusted ?

      I'd go with a vodka tonic, but that's just me😉

      Draft gluten-free ciders… can they be trusted ?

      That and my nutritionist also said that drinking cider is one of the worst drink choices for me, given that I have candida overgrowth.  She said the combination of the alcohol and sugar would be very likely to worsen my candida problem.  She suggested that if I drink, I go for clear vodka, either neat or with a splash of cranberry.   So in summary, I am giving ciders a rest.  Whether it's a gluten risk or sugars and yeast overgrowth, its just not worth it.

      Tea Bags and Gluten

      By Scott Adams · Posted

      While plain, pure tea leaves (black, green, or white) are naturally gluten-free, the issue often lies not with the tea itself but with other ingredients or processing. Many flavored teas use barley malt or other gluten-containing grains as a flavoring agent, which would be clearly listed on the ingredient label. Cross-contamination is another possibility, either in the facility where the tea is processed or, surprisingly, from the tea bag material itself—some tea bags are sealed with a wheat-based glue. Furthermore, it's important to consider that your reaction could be to other substances in tea, such as high levels of tannins, which can be hard on the stomach, or to natural histamines or other compounds that can cause a non-celiac immune response. The best way to investigate is to carefully read labels for hidden ingredients, try switching to a certified gluten-free tea brand that uses whole leaf or pyramid-style bags, and see if the reaction persists.

      Inconclusive results

      By Scott Adams · Posted

      This is a challenging and confusing situation. The combination of a positive EMA—which is a highly specific marker rarely yielding false positives—alongside strongly elevated TTG on two separate occasions, years apart, is profoundly suggestive of celiac disease, even in the absence of biopsy damage. This pattern strongly aligns with what is known as "potential celiac disease," where the immune system is clearly activated, but intestinal damage has not yet become visible under the microscope. Your concern about the long-term risk of continued gluten consumption is valid, especially given your family's experience with the consequences of delayed diagnosis. Since your daughter is now at an age where her buy-in is essential for a gluten-free lifestyle, obtaining a definitive answer is crucial for her long-term adherence and health. Given that she is asymptomatic yet serologically positive, a third biopsy now, after a proper 12-week challenge, offers the best chance to capture any microscopic damage that may have developed, providing the concrete evidence needed to justify the dietary change. This isn't about wanting her to have celiac; it's about wanting to prevent the insidious damage that can occur while waiting for symptoms to appear, and ultimately giving her the unambiguous "why" she needs to accept and commit to the necessary treatment. This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.
