Question About Ttg

I went to the doctors to get a copy of my celiac 'panel', if thats what you want to call it.

The only thing they tested was my ttG (t Transglutaminase antibody) and it was negative.

How accurate is it? Does this mean for sure that I don't have Celiac's?

Thank you!

-Kim

It is not unheard of to have a negative TtG and still have celiac. The problem is compounded by the fact that they did not run the complete celiac panel. Without the Total IgA score, it i impossible to know whether or not one is IgA deficient. If it were me, I would return to the doctor by phone ir in person, and request the full celiac panel.

Antigliadin IgA and IgG

Anti-tissue Transglutaminase Antibody (tTG) IgA and IgG

Anti-endomysial IgA and IgG

Total serum IgA

It is also possible to have a negative TtG when the damage is still in its early stages.

Both the anti-tTG and the EMA titers correlate with the severity of villous atrophy [26-29]. As a result in the presence of partial villous atrophy either antibody may be negative. In addition the mode of presentation of the celiac disease, i.e. presence of silent or subclinical celiac disease may be associated with a negative EMA [30]. Clinically seronegative celiac disease is similar to sero-positive celiac disease [23, 28] In view of the possibility of the presence of celiac disease in the absence of a positive anti-tTG or endomysial antibody the presence of a positive IgA AGA should prompt a biopsy [13]. Several studies have demonstrated that reliance on either anti-tTG or endomysial antibody as a single test will underestimate the prevalence of celiac disease [23, 25, 31, 32].

Thank you so much for providing me with that information :) That helped so much.

      This is a very common question, and the most important thing to know is that no, Guinness is not considered safe for individuals with coeliac disease. While it's fascinating to hear anecdotes from other coeliacs who can drink it without immediate issues, this is a risky exception rather than the rule. The core issue is that Guinness is brewed from barley, which contains gluten, and the standard brewing process does not remove the gluten protein to a level safe for coeliacs (below 20ppm). For someone like you who experiences dermatitis herpetiformis, the reaction is particularly significant. DH is triggered by gluten ingestion, even without immediate gastrointestinal symptoms. So, while you may not feel an instant stomach upset, drinking a gluten-containing beer like Guinness could very well provoke a flare-up of your skin condition days later. It would be a gamble with a potentially uncomfortable and long-lasting consequence. Fortunately, there are excellent, certified gluten-free stouts available now that can provide a safe and satisfying alternative without the risk.

      Interestingly, this thought occurred to me last night. I did find that there are studies investigating whether vitamin D deficiency can actually trigger celiac disease.  Source: National Institutes of Health https://pmc.ncbi.nlm.nih.gov/articles/PMC7231074/

      Before being diagnosed coeliac I used to love Guinness. Being made from barley it should be something a coeliac shouldn’t drink. But taking to another coeliac and they can drink it with no ill effects and have heard of others who can drink it too.  is this everyone’s experience?  Can I drink it?  I get dermatitis herpetiformis and don’t get instant reactions to gluten so can’t try it to see for myself.

      NCGS does not cause damage to the small bowel villi so, if indeed you were not skimping on gluten when you had the antibody blood testing done, it is likely you have celiac disease.

      I will assume you did the gluten challenge properly and were eating a lot of gluten daily for 6-8 weeks before your test, but if not, that could be the issue. You can still have celiac disease with negative blood test results, although it's not as common:  Clinical and genetic profile of patients with seronegative coeliac disease: the natural history and response to gluten-free diet: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5606118/  Seronegative Celiac Disease - A Challenging Case: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9441776/  Enteropathies with villous atrophy but negative coeliac serology in adults: current issues: https://pubmed.ncbi.nlm.nih.gov/34764141/  Approximately 10x more people have non-celiac gluten sensitivity than have celiac disease, but there isn’t yet a test for NCGS. If your symptoms go away on a gluten-free diet it would likely signal NCGS.
