Curious - Q for Seronegative Celiacs & NCGS - did you gene test?

I am seeking more info from seronegative celiacs (celiacs where the blood tests did not show it) but later biopsy confirmed & from NCGS diagnosed whose symptoms were allieviated on the gfd 

What blood tests for celiac disease did you do? / Were your numbers totally low / normal?

Were you gene typed?

What were your results of gene typing?

I'm especially curious to try to get a sense of if there are other DQ7 types out there who were seronegative.... but had symptoms resolve on the diet.

Also were any of you ANA tested?

(Asking because my kids are at risk. Half my husbands family are biopsy-confirmed celiacs - but most with weird paths to diagnosis - he was confirmed through DH skin biopsy / his sis never had a positive blood test but had tons of Marsh III lesions at time of endoscopy / first cousin had one equivical positive blood test as teen, when no damage was found on initial endoscopy doc advised her gluten was fine -- six years later new endoscopy showed major damage. Curious if there is a tie between genetic types. They haven't all been gene typed but we know my husband is DQ7)

My brother was reportedly seronegative. However, I recently found out he had only the TTG and EMA done. They did not run the DGP. He is DQ2, positive biopsy. His son was screened, also only for tTG and EMA and was negative. He has DQ2 though.

I am TTG and EMA negative. My DGP is negative when separated into DGP IGA and IGG, however, it is positive on a combined screen. This is funky. The positive number did not fluctuate greatly from a gluten free diet to a gluten challenge. So we are not sure how reliable it is. I am DQ2 positive. ANA was normal. First biopsy normal, second showed inflammation only, final endoscopy was done with a specialist and biopsy showed Marsh 2-3A, increased IEL, crypt hyperplasia. 

I am in a similar boat. Need to have my son screened and the genetic test is not covered. Plus, not all docs run the DGP which although can be a false positive, can also be useful in screening, especially in my family's case. I am exploring trying to make it work locally or bringing my son to see my out of state specialist when I return for follow up biopsy next year. I hate to wait a year, but he seems happy and healthy. However, we too do not present with the text book classic symptoms in my family either. 

Good luck!

I'm a NCGS and the gfd has helped me a lot. My symptoms were neurological, GI and gynecological problems. A family member has celiac and two other family members (who are deceased) had gastrointestinal cancer and epilepsy.

In fact, I may be a seronegative celiac. My blood tests were negative but I didn't have an endoscopy/biopsy (lack of trust in doctors).

Gliadin IgG 0,2 (Ref.: 0,0 – 0,9) neg.

Gliadin IgA 0,1 (Ref.: 0,0 – 0,9) neg.

Endomysium IgG negative

Endomysium IgA negative

ttg IgG 0,1 (Ref.: 0,0 – 0,9) neg.

ttg IgA 0,1 (Ref.: 0,0 – 0,9) neg.

total IgA 1,98 (Ref.: 0,70-4,00)

No. It's quite expensive and I can't afford it now. But, I'd like to get these genetic tests in the future.

No, but I do have some thyroid issues - borderline hypothyroidism (TSH was borderline high).

To be honest, this is exactly the reason I've decided not to rely on the negative blood test results. I don't want to keep on eating gluten for x more years only to find out that the damage is 'already severe enough' to be detected.

I had 23andme testing which showed I have genes DQ2.5 and DQ8. When I learned this I decided to stop eating gluten to PREVENT getting celiac, but didn't worry about cross-contamination. A year later I got sick, and eventually had an endoscopy which showed Marsh 1. My blood tests were negative, as one would expect for anyone eating gluten-free. My gastroenterologist told me I could either decide to live like a celiac, or do the full 12-week gluten challenge. I cleaned up my kitchen and started being very careful with eating away from home, and my symptoms went away.

      My journey is it gluten or fiber?

      By Scott Adams · Posted

      In general if it is certified gluten-free serious steps are taken to avoid cross-contamination, but things can still happen in a shared facility, and gluten-free certification isn't a guarantee, as we've seen recently:

      Dizziness after eating green beans?

      By Scott Adams · Posted

      As already mentioned here, and based on your description, this sounds like a serious and specific reaction to green beans. While your prior allergy tests didn't flag legumes, it's possible to develop a new allergy at any time. The symptoms you describe—extreme dizziness, racing heart, sweating, and itching—are consistent with a systemic allergic response, not just an intolerance. Given your history of celiac disease and tree nut allergies, your immune system is already predisposed to sensitivities. It is crucial to stop consuming green beans immediately and consult an allergist. They can perform more specific testing and may prescribe an epinephrine auto-injector for emergency use, as this type of reaction can be unpredictable and potentially escalate.

      Slow healing?

      By Eric.C · Posted

      I was diagnosed with celiac disease in October last year and followed a strict gluten free diet since then. My dietitian told me that my diet looks absolutely perfect and I can’t think of many possible ways to get cc as I am very strict. However, when I did my check up gastroscopy a year later my healing only showed a slow improvement going from marsh 3b - 3a. Is this normal healing for a year? My main symtoms pre- diagnosis was joint/back pain, poor immune system and stomach problems (especially in the morning). Joint pain and the immune system improved almost instantly but the stomach problems still persist (but has gotten better). For reference I am a 21 year old male and both my ttg levels were normal after just 4 months and also the test for calkprotekin. My diet consists of 99% home cooked meals in a kitchen free from gluten.

      I read that as well but I saw the Certified Gluten free symbol that is the reason I ourchased it.

      Issues before diagnosis

      By cristiana · Posted

      I agree, it so often overlooked! I live in the UK and I have often wondered why doctors are so reluctant to at least exclude it - my thoughts are perhaps the particular tests are expensive for the NHS, so therefore saved for people with 'obvious' symptoms.  I was diagnosed in 2013 and was told immediately that my parents, sibling and children should be checked.  My parents' GP to this day has not put forward my father for testing, and my mother was never tested in her lifetime, despite the fact that they both have some interesting symptoms/family history that reflect they might have coeliac disease (Dad - extreme bloating, and his Mum clearly had autoimmune issues, albeit undiagnosed as such; Mum - osteoporosis, anxiety).  I am now my father' legal guardian and suspecting my parents may have forgotten to ask their GP for a test (which is entirely possible!) I put it to his last GP that he ought to be tested.  He looked at Dad's blood results and purely because he was not anemic said he wasn't a coeliac.  Hopefully as the awareness of Coeliac Disease spreads among the general public, people will be able to advocate for themselves.  It is hard because in the UK the NHS is very stretched, but the fallout from not being diagnosed in a timely fashion will only cost the NHS more money. Interestingly, a complete aside, I met someone recently whose son was diagnosed (I think she said he was 8).  At a recent birthday party with 8 guests, 4 boys out of the 8 had received diagnosis of Coeliac Disease, which is an astounding statistic  As far as I know, though, they had all had obvious gastric symptoms leading to their NHS diagnosis.  In my own case I had  acute onset anxiety, hypnopompic hallucinations (vivid hallucinations upon waking),  odd liver function, anxiety, headaches, ulcers and low iron but it wasn't until the gastric symptoms hit me that a GP thought to do coeliac testing, and my numbers were through the roof.  As @trents says, by the grace of God I was diagnosed, and the diet has pretty much dealt with most of those symptoms.  I have much to be grateful for.
