Understanding blood panels

Hi there, 

I've read other people posting their results from their coeliac blood tests with a number within a reference range. However my blood panels didn't contain a number. It said:

Diamidated Gliadin IgG Ab (Bioplex) : not detected

t-Transglutaminase IgA Ab (Bioplex) : not detected

 

There was also a comment saying negative results could be seen in people with coeliac already on a gluten-free diet. Which I think I may have been when this was done... 

Do these tests indicate anything about IgA deficiency? Is it worth doing a gluten challenge or is it very very unlikely that I have it? 

Somehow I naturally don't eat much gluten. I don't like the feeling I get afterwards! 

 

Thanks for your thoughts.

Looking at the technical/FDA information for BioPlex, it looks a little different from some other tests.  One test looks for IgA for both TTG and DGP, along with IgA deficiency, and the other looks for IgG for both TTG and DGP.  So it looks like you were tested for everything. I don’t know why the lab wouldn’t put your actual numbers but “not detected” would certainly mean negative for celiac antibodies.

If you weren’t eating gluten the tests wouldn’t be accurate however.

      Being a burden to family/friends

      Being a burden to family/friends

      By CatS · Posted

      I understand your frustration about socializing while having celiac disease. I also have allergies to nuts, dairy, all forms of gluten including oats, strawberries and MSG. I get anxiety while grocery shopping and really take my time to read all labels. I always carry a magnifying glass with me wherever I go to read labels. Many products are labelled Gluten Free but contain Oats, and apparently this is becoming more common. I almost bought some gluten free flour but read that it contained oats. A certain percentage of Celiacs have this complication. I can’t help feeling offended and excluded when others act like I am being “high maintenance”. I am becoming better at being an advocate for myself.  I have had diverticulitis 3 times and each time hospitalized-once, the attending nurse didn’t know what celiac means-she had to research...  If others around me make comments I try to enlighten them, those who don’t get it are not my friends anymore. Be very careful about cross-contamination. I was sick recently for 10 days after a meal was contaminated while I was on holiday. If servers say they have gluten free buns or bread, ask if they use a toaster specifically reserved for gluten-free, or don’t chance it. On a positive note, I didn’t find out I had Celiac Disease until I was 60. Eating a gluten free diet means no more terrible headaches, hives, rashes, intestinal bloating and irregularity, Gastro Intestinal Reflux….when I follow a strict diet and mostly always eat at home, I feel great! I also weeded out “friends” who weren’t worth being around.

      Delayed reaction

      By Scott Adams · Posted

      I agree with @trents, it's not typical for gluten exposure to cause symptoms as delayed as a week or two after ingestion. In most cases, reactions to gluten occur within hours to a few days, depending on individual sensitivity and how much gluten was consumed. The delayed symptoms you describe—stomach cramping in the mornings and flaky stool—might suggest that something else is contributing to your discomfort. Cross-contamination is a common challenge, especially when dining out, and it's great that you're doing your best to stay gluten-free. However, the inconsistency of your symptoms and the long delay between exposure and reaction could warrant further investigation. It's possible that another gastrointestinal condition, such as IBS, a food intolerance, or a reaction to something else in your diet, might be contributing to your symptoms. You might consider keeping a detailed food and symptom diary to identify potential patterns or triggers. Additionally, consulting your gastroenterologist could provide clarity. They may suggest testing to rule out other issues, such as small intestinal bacterial overgrowth (SIBO), microscopic colitis, or other sensitivities. If you suspect cross-contamination is a significant issue, you could also ask for follow-up bloodwork (e.g., tTG-IgA) to check if your antibodies are elevated, which might indicate ongoing gluten exposure.
