Positive Genetic Test- Negative Blood Work

I recently had genetic testing and lab work for celiac from prometheus labs, ordered by my doctor. My doctor said I came back positive for having all the genes celiacs have but my blood work was negative. How much gluten do you have to eat to get positive results? I dont avoid it completely but I definitely eat a gluten restricted diet. What next? I have too many health issues and symptoms to just accept that i have inactive celiac genes. Ive had candida overgrowth and just got diagnosed with bacterial overgrowth. Should i request a biopsy or additional testing? Also do I need to have my 2 young children tested now? HELP!

OK, since you have the genes and symptoms, I would say you likely have it. The problem is that blood tests and biopsies can be false negative. The true test, IMHO is positive dietary response. You can have the biopsy, but remember that there are over 35 ft of intestine, and they only test 6 samples. So, it could be negative, too, even with Celiac. Or you could have gluten intolerance, which will never show up on a blood test or biopsy, but the symptoms are the same.

as for your kids, kids tests are notoriously inaccurate. Are they symptomatic? My 9 yr tested positive, but my 13 does not. Even though he vomits for most of the day after eating gluten.

I would suggest doing a strict gluten free trial, with a gluten free house to ensure you don't get cross contamination, for 3 months. If you have improved your symptoms you may have your answer. Then after 3 months you could challenge it.

After all I have learned, I don't think the official diagnosis is worth it, unless you live outside of the US where you get benefits. Too many people struggle for years with no diagnosis. And you don't need a diagnosis to try the diet to see if it works for you.

That's my two cents. And yes, I know that I am opinionated in this matter :D

I am somewhat in the same boat. I tested positive for genes and negative for blood work. I had been gluten free for 9mos so I did a 3 month gluten challenge in order to do a biopsy. The results of the biopsy were sort of inconclusive saying I showed signs of "suggestive early/mild celiac" and they want me to continue eating gluten for 3 more months and do biopsy again.

SO...my choices are 1. just go gluten free or 2. redo the biopsy

I am not at the place where many other seem to be able to accept that and just go gluten free w/out the diagnosis. I just REALLY, REALLY want to know for sure if I have it before going gluten free for the rest of my life. I am 100% happy to stop gluten, but I feel such a strong desire to have an official diagnosis.

AND..I have to think about my kids as well.

Good Luck.

Debbie

Yea, i also feel i really want a definite diagnosis. I have been eating a "gluten restricted" diet for at least 2.5 years. I def don't eat an equivalent of 3-4 slices of bread a day! My doctor seems to think that having even a little gluten in your diet will yield a positive or at least slightly positive result. Im just NOT convinced, i still need more answers. I wonder if im eating enough gluten for a biospy to be positive. Im thinking of getting the entero lab stool test to get a diagnosis, anyone know if this is accurate?

There are no 'Celiac genes', only a subset of HLA haplotypes that are associated with Celiac - like blue eyes and blond hair are associated. You can have one without the other.

I was thinking of doing the Entero Lab too....wondering if that might be more info to help me put the pieces together!?!?

yes but the test did not say i only had one or some of the genes, it said i had ALL the genes associated with celiacs- so either i have celiacs or i could DEFINITELY develop it in the future

I just saw an expert GI who is also giving me this test due to yrs of gerd, and the past 2 yrs having neurpathy/neuro issues and past yr inflammation of pancreas. My other dr did not run the proper labs. Oy. Anyway, he said if my genetic tests come back POS but labs NEG he will do a biopsy of my stomach as it would be VERY likely I have it. Gluten does not always show in labs...

      This article does not address migraines at all. Yes, red wine and sulfites are often mentioned in connection with migraine triggers.

      Then we would need to cut out all meat and fish as they are richer sources of tyrosine than nuts and cheese. Something else about certain tyrosine rich foods must be the actual culprit.

      KAN-101 Treatment for Coeliac Disease

      I agree that KAN-101 looks promising, and hope the fast track is approved. From our article below: "KAN-101 shows promise as an immune tolerance therapy aiming to retrain the immune system, potentially allowing safe gluten exposure in the future, but more clinical data is needed to confirm long-term effects."

      Body dysmorphia experience

With me, any kind of alcoholic beverage in very modest amounts will reliably produce a migraine. Nitrous oxide generators, which are vaso dialators, also will give me migraines reliably. So, I think most of my migraines are tied to fluctuations vascular tension and blood flow to the brain. That's why the sumatriptan works so well. It is a vaso constrictor.

      Excessive dietary tyrosine can cause problems.  Everything in moderation.   Sulfites can also trigger migraines. Sulfites are found in fermented, pickled and aged foods, like cheese.  Sulfites cause a high histamine release.  High histamine levels are found in migraine.  Following a low histamine diet like the low histamine Autoimmune Protocol diet, a Paleo diet, helps immensely.    Sulfites and other migraine trigger foods can cause changes in the gut microbiome.  These bad bacteria can increase the incidence of migraines, increasing histamine and inflammation leading to increased gut permeability (leaky gut), SIBO, and higher systemic inflammation.   A Ketogenic diet can reduce the incidence of migraine.  A Paleo diet like the AIP diet, that restricts carbohydrates (like from starchy vegetables) becomes a ketogenic diet.  This diet also changes the microbiome, eliminating the bad bacteria and SIBO that cause an increase in histamine, inflammation and migraine.  Fewer bad bacteria reduces inflammation, lowers migraine frequency, and improves leaky gut. Since I started following the low histamine ketogenic AIP paleo diet, I rarely get migraine.  Yes, I do eat carbs occasionally now, rice or potato, but still no migraines.  Feed your body right, feed your intestinal bacteria right, you'll feel better.  Good intestinal bacteria actually make your mental health better, too.  I had to decide to change my diet drastically in order to feel better all the time, not just to satisfy my taste buds.  I chose to eat so I would feel better all the time.  I do like dark chocolate (a migraine trigger), but now I can indulge occasionally without a migraine after.   Microbiota alterations are related to migraine food triggers and inflammatory markers in chronic migraine patients with medication overuse headache https://pmc.ncbi.nlm.nih.gov/articles/PMC11546420/

      Body dysmorphia experience

      By Scott Adams · Posted

      Thank you so much for having the courage to share this incredibly vivid and personal experience; it's a powerful reminder of how physical ailments can disrupt our fundamental sense of self. What you're describing sounds less like a purely psychological body dysmorphia and more like a distinct neurological event, likely triggered by the immense physical stress and inflammation that uncontrolled celiac disease can inflict on the entire body, including the nervous system. It makes complete sense that the specific sensory input—the pressure points of your elbows on your knees—created a temporary, distorted body map in your brain, and the fact that it ceased once you adopted a gluten-free diet is a crucial detail. Your intuition to document this is absolutely right; it's not "crazy" but rather a significant anecdotal data point that underscores the mysterious and far-reaching ways gluten can affect individuals. Your theory about sensory triggers from the feet for others is also a thoughtful insight, and sharing this story could indeed be validating for others who have had similar, unexplainable sensory disturbances, helping them feel less alone in their journey.
