My doctor isn't available for a few days to discuss my results and I was hoping someone may be able to help me interpret this. They seem to be conflicting.

Welcome to the forum, jennmb!

Celiac Ab tTG DGP TIgA
Immunoglobulin A, Qn, Serum01 363 High mg/dL

This one is the only "high" value from your testing. It is not a test to diagnose celiac disease per se but is a measure of total serum IGA antibody levels. The fact that it is high does not necessarily mean anything. If it were low, on the other hand, it could have caused false negatives for the individual IGA antibody tests and would trigger the need for more tests to be run. So, this would not be a problem for you. Your other celiac antibody tests are all negative.

Having said all that, had you already started on a gluten free diet before the blood draw? If so, how long? This can sabotage testing for celiac disease.

Your negative celiac antibody testing does not rule out the possibility of NCGS (Non Celiac Gluten Sensitivity) which shares many of the same symptoms with celiac disease, is 10x more common but for which there is no reliable testing available yet. A diagnosis of NCGS would be appropriate if celiac-like symptoms are present while still consuming gluten but actual celiac tests are negative. In other words, celiac disease must first be ruled out.

What symptoms have you been having?

Thank you for your response! I didn't make any changes to my diet. It usually have gluten on a very regular basis. My primary symptom is ongoing stomach discomfort and cramping. I don't regularly have other symptoms. I'll get random bouts of things but i feel like everyone does and they don't really bother me. So far, most of my blood tests and scans all appear normal.

Has there been any thought given to an endoscopy/biopsy which is the gold standard diagnostic tool for celiac disease? If the biopsy shows damage to the villous lining of the small bowel then it is reasonable to conclude celiac disease.

Not at this time. I'll bring it up when I speak with them next.

      Hidden Gluten in distilled vinegar

      By knitty kitty · Posted

      @Manaan2,  I'm so happy to hear you're going to try thiamine and magnesium!  Do let us know the results!   You may want to add a B 50 Complex with two meals of the day to help boost absorption.  Thiamine interacts with each of the other B vitamins which are all water soluble.   When supplementing magnesium, make sure to get sufficient calcium.  Calcium and magnesium need to be kept in balance.  If you choose a calcium supplement, take two hours apart from magnesium as they compete for absorption.  Take Calcium with Vitamin D.  Vitamin D helps calm the immune system.   For pain, I use a combination of thiamine, B12 Cobalamine, and Pyridoxine B6.  These three vitamins together have analgesic effects.  My preferred brand is "GSG 12X Takeda ALINAMIN EX Plus Vitamin B1 B6 B12 Health Supplementary from Japan 120 Tablets".  Alinamin is another form of thiamine.  It really takes is excellent at relieving my back pain from crushed vertebrae without side effects and no grogginess.   Look into the low histamine version of the Autoimmune Protocol Duet (Dr. Sarah Ballentyne, a Celiac herself developed it.)  It really helps heal the intestines, too.  It's like a vacation for the digestive system.  Add foods back gradually over several weeks after feeling better.   I'm so happy to have pointed the way on your journey!  Let us know how the journey progresses!

      @knitty kitty I can't thank you enough!  My husband and I already started looking into those supplements.  We definitely plan to give it a try.  We've been against the Miralax since it was originally advised by PCP, but because of the level of pain she experienced on a daily basis, we decided to try it.  We've made many attempts to gradually decrease but due to her pain and related symptoms, we've kept her on it while trying all sorts of other dietary adjustments pre and post diagnosis specific to food; so far none of those efforts have made a significant difference.  I will definitely share how she's doing along the way!

      Opinions on my test results/symptoms

      By BIg Nodge · Posted

      Hi, I have recently embarked on the gluten-free journey. I have what to me seems like a somewhat confusing set of test results and symptoms. I have been impressed by the accumulated knowledge and thoughtfulness as I browse this forum, so I figured I'd make a post to see if anyone can offer any insight. I know there are many posts like this from new users, so I have tried to do my baseline research first and not ask super obvious questions.  I'm 43, overall very healthy. No history of gluten sensitivity or really any of the classic GI symptoms. About three years ago I started to experience intermittent bouts of fatigue, chills/cold intolerance, and shortness of breath/air hunger (sometimes feels like a hollowness in my chest, hard to describe). The symptoms over time have become fairly significant, though not debilitating, I am able to exercise regularly and am fairly physically active, continue to perform well at work. But for example I have gone from someone who consistently ran hot, was always cranking the a/c, to someone who wears a down vest inside at work in winter and get chills if the a/c even blows on me in summer. I get tired and lose energy even when getting decent amounts of sleep, and have to have my wife take over on long drives that I could previously handle with no problems. More generally when I am experiencing these symptoms they seem to crowd out space in my mind for focusing on my family, my hobbies/activities etc, I sort of withdraw into myself.   I happened to be experiencing these symptoms during an annual physical with my PCP a few years ago, he observed post nasal drip and suggested it was allergies and that I treat it with claritin. At first it seemed to respond to claritin (though not zyrtex), but over time I became unsatisfied with that answer. There didn't seem to be any seasonal rhyme or reason to my symptoms, and I felt like I was on an endless loop of taking claritin, then stopping, not being sure if it was even making a difference. I did eventually get allergy tests and found modest allergies to dust and pollen, which didn't feel like a smoking gun.  I then started seeing a natural medicine doctor who was much more willing to explore my symptoms via testing. The first thing that came back abnormal was elevated thyroid peroxidase antibodies/TPOs, 137 IU/mL vs a reference range of <9. At the same time my thyroid panel showed normal thyroid hormone levels. So it appears my immune system is attacking my thyroid even though it is working fine. I got a thyroid ultrasound at the time, it was clear, but with some abnormalities such that they suggested I get is scanned again in a year. These are certainly risk factors for a thyroid autoimmune disease, though my thyroid seems to be working fine for now.  From here my doctor considered celiac due to the murky thyroid/celiac links, so we did a panel. Results were as follows: TT IGA <1 U/ml, TT IGG <1 U/ml, deamidated gliadin IGA 24.6 U/ml, deamidated gliadin IGG <1 U/ml, IGAs 170 mg/dL. Readings greater than 15 considered high by my lab for the first four, my IGAs are within reference range. So basically just the deamidated IGA popped, but my IGAs are normal. I also notice on the tests that my thyroglobulin was high, 86.7 ng/ml vs a range of 2.8 - 40.9.  My doctor suggested that it certainly wasn't conclusive for celiac, but it was possible, and likely that I have some sort of gluten sensitivity. She suggested going gluten free and seeing how I felt as opposed to doing a biopsy. The best theory I can come up with is perhaps I am a silent celiac or just have a gluten sensitivity that doesn't produce immediate GI symptoms, but is still doing damage and over time has caused leaky gut. So now gluten is getting into my blood, and my immune system is attacking it but also mistakingly attacking my thyroid.  So that's what I did, went gluten free in October. It's been about four months, and I am really not feeling any difference. I still get the same symptoms that come and go. My bowel movements may be a bit more regular, but it was never a major issue before so I would consider that a minor improvement. I know that it can take a while to see improvements, and I am going to remain gluten-free and see how I feel. But I am definitely questioning whether I really understand what is going on, and am open to any thoughts or suggestions from the forum. Sometimes I wish I just went ahead with the biopsy before going gluten-free. While I would certainly be down to start drinking IPAs again ahead of a biopsy, you know, for science, I feel like at this point I would be throwing away four months of work and am better off staying the course and seeing what happens. But I'm really not sure.  I know there is a lot of thyroid knowledge on these boards, along with the celiac expertise, so I'm curious if this resonates with anyone's experience. And I'm interested in what sort of timelines people have experienced in terms of feeling improvements for some of these non-GI symptoms like chills, SOB, brain fog etc. Thanks in advance.

      Testing positive for antibodies, are there visible changes to the colon that could be seen without a biopsy?

      By cameo674 · Posted

      Does it taste like black licorice?  It said it was chewable.  I do not like that flavor.     Since the burn at the back of my throat is there everyday, I usually only take something when it is unbearable and keeping me from ADL especially sleep.

      Nandos improper preparion celiac childrens food

      By Scott Adams · Posted

      Your concerns about Nando's cross-contamination practices are valid and important for the celiac community. It's disappointing that Nando's does not have stricter protocols for children's portions, especially given the risk of cross-contact with gluten-containing items like garlic bread. Cooking gluten-free items on shared surfaces, even if cleaned, is not safe for individuals with celiac disease, as even trace amounts of gluten can cause harm. While the adult butterfly chicken may be a safer option, the inconsistency in practices for children's meals is concerning. It's frustrating that Nando's headquarters did not take responsibility, but sharing your experience raises awareness and may encourage them to improve their protocols. Consider reaching out to celiac advocacy organizations to amplify your concerns and push for better standards. Always double-check with staff and emphasize the importance of avoiding cross-contamination when dining out.
