Bloodwork Question...


stomica

Recommended Posts

stomica Rookie

My 3 year old daughter was tested for celiac about 6 months ago...the antigliadin IgA's and IgG's were both elevated but the reticulin and endomysial antibodies were negative. Because the antigliadin antibodies were elevated, the ped GI wanted to retest her, which we just did last week. Course they performed different tests this time, so we're unable to compare, but they did the endomysial and the ttg tests which were negative. Her total IgA's (not antigliadin specific) were actually elevated, so she's not IgA deficient. Just wondering if I should interpret this bloodwork as an absolute negative. The allergist did suggest trying a gluten-free diet due to the possibility of a wheat intolerance instead of celiac. Just wondering what your thoughts are! Thanks in advance!

Kid's with Celiac by Danna Korn has a chart in it for test results.

+ EMA-Iga/tTG

+AGA-IgG

=Interpretation - Celiac Disease almost certain

That is directly from the book and I am not a doctor!

So you're saying if the endomysial antibody is positive, along with the anti-gliadin IgG...then celiac is almost certain? Well, my daughter's EMA was negative on two different occasions. Funny, the allergist said that many people can have elevated anti-gliadin IgG's, but the IgA's were the ones that were most correlated with celiac. I would definitely be inclined to believe this man - he's very knowledgable and very well respected. (He's also very open minded, which is definitely a plus!) Thanks for your reply!

Your allergist is correct -- elevated IgG for gliadin is not necessarily specific for celiac. EMA is both very specific for celiac and a very good predictor (so a negative means negative most of the time...). IgA can be negative because you are celiac and don't have any, or negative because you aren't celiac at all. If your daughter's came back elevated, you know she actually has IgAs running around. Anyhow, a negative EMA and a negative tTg is going to be negative for celiac in most people's cases....

Don't really want to cause more confusion, but I thought I should point out that a positive IgA antigliadin test shows a reaction to gliadin(gluten), negative IgA tTg and EMA mean that the damage to the intestine is not severe enough to be called celiac, but your allergist is correct that it could be an intolerance to wheat (or gluten) and just not full blown Celiac. No one can say for certain if your daughter will get Celiac Disease later, but you could avoid it all toghether by trying the diet. I assume she must have symptoms or you wouldn't be testing her? If you are finished with testing at this point then it wouldn't be a bad thing to try the diet like the allergist suggested. If her symptoms improve, then you can be pretty sure that gluten is bothering her. You could also have her gene tested. Enterolab does a very good gene test, that included the genes for gluten intolerance, as well as the main genes for Celiac. It costs about $150. You don't need a doctors order either, and you do the test at home. Some people like the idea of having the gene test be private, since they don't want to be discriminated against by future insurance companies who don't want to cover you because you have a genetic disorder...So with Enterolab you have the choice of sharing the results with your doctor or not.

God bless,

Thanks for all the info! Yes my daughter does have symptoms, but she was actually diagnosed with inflammatory bowel disease. I still am a bit skeptical about the diagnosis, so I find myself questioning other possibilities. Her ped GI said she could have celiac in addition to IBD so that's why she's been tested. Her symptoms include loose, foul stools with mucous and, on occasion, trace amounts of blood. We first thought it was a dairy allergy. When we took dairy out of her diet, the blood increased. We did the elimination diet twice - the first time for 3 weeks and the second for 2 weeks. Both times, the blood in her stool increased. I know celiac doesn't normally cause blood, but I'm just wondering why taking dairy out increased her symptoms. Seems she was eating more wheat at the time to make up for the lack of dairy, so it seems logical that she was having some sort of reaction to wheat. But I guess you could also explain it by saying that gluten is tough on the body...it can be even tougher on a damaged intestinal tract causing more blood to appear. Anyway, enough about that. Thanks again for all the info! (By the way, I thought about Enterolab, but I'm very skeptical about the accuracy of the tests.)

  Funny, the allergist said that many people can have elevated anti-gliadin IgG's, but the IgA's were the ones that were most correlated with celiac.

Unfortunately, it is very true... and it means that there are A LOT of people out there with a gluten intolerance that aren't being helped. Elevated IgA is more specific to damage in the intestines... but an elevated IgG is nothing to ignore. The IgG antibodies are the one's that roam freely throughout the body and they are the one's, I believe, are causing the 'other' disorders that have been linked to celiac disease: thyroid, arthritis, diabetes...

If you have a gluten intolerance, evidenced by elevated antibodies to gliadin (IgA or IgG), then the only way to prevent from developing any disorder is to abstain from gluten.

The cure is simple and you don't need a prescription or a doctor to do it! :)

      Welcome to the celiac.com community, @ainsleydale1700! First, it is very unlikely, given your genetic results, that you have celiac disease. But it is not a slam dunk. Second, there are some other reasons besides having celiac disease that your blood antibody testing was positive. There are some diseases, some medications and even (for some people) some foods (dairy, the protein "casein") that can cause elevated celiac blood antibody test scores. Usually, the other causes don't produce marginally high test scores and not super high ones. Having said that, by far, the most common reason for elevated tTG-IGA celiac antibody test scores (this is the most common test ordered by doctors when checking for celiac disease) is celiac disease itself. Please post back and list all celiac blood antibody tests that were done with their scores and with their reference ranges. Without the reference ranges for negative vs. positive we can't tell much because they vary from lab to lab. Third, and this is an terrible bum steer by your doc, for the biopsy results to be valid, you need to have been eating generous amounts of gluten up to the day of the procedure for several weeks.  Having said all that, it sounds most likely that you have NCGS (Non Celiac Gluten Sensitivity) as opposed to celiac disease. The two share many common symptoms but NCGS is not autoimmune in nature and doesn't damage the lining of the small bowel. What symptoms do you have? Do you have any blood work that is out of norm like iron deficiency that would suggest celiac disease?

      HLA testing can definitely be confusing. Classic celiac disease risk is most strongly associated with having the full HLA-DQ2 or HLA-DQ8 heterodimer, which requires specific DQA1 and DQB1 genes working together. Your report shows you are negative for the common DQ2 and DQ8 combinations, but positive for DQB102, which is one component of the DQ2 pair. On its own, DQB102 does not usually form the full DQ2 molecule most strongly linked to celiac disease, which is likely why your doctor said you do not carry the typical “celiac genes.” However, genetics are only part of the picture. A negative gene test makes celiac disease much less likely, but not absolutely impossible in rare cases. More importantly, both antibody testing and biopsy are only reliable when someone is actively eating gluten; being gluten-free for four years before testing can cause both bloodwork and intestinal biopsy to appear falsely negative. Given your positive antibodies and ongoing symptoms, it may be reasonable to seek clarification from a gastroenterologist experienced in celiac disease about whether proper gluten exposure was done before testing and whether additional evaluation is needed.

      I agree with your post and have had similar experiences. I'm commenting to add the suggestion of also using nutritional yeast as a supplement. It's a rich source of B vitamins and other nutrients, and some brands are further supplemented with additional B12. I sprinkle a modest amount in a variety of savory recipes.

      Hi, could someone help me understand the result of my gene test? DQ2 (DQA1 0501/0505,DQB1 02XX): Negative DQ8 (DQA1 03XX,DQB1 0302): Negative The patient is positive for DQB1*02, one half of the DQ2 heterodimer.  The doctor said I don't have Celiac genes.  I asked him to clarify about my positive DQB1*02, and he said it's a gene unrelated to Celiac.  I have all the symptoms and my bloodwork is positive for antibodies, despite being on a gluten-free diet for the past 4 years.  He also did a biopsy but told me to continue a gluten-free diet and not eat gluten before the biopsy.  Based on the gene test and biopsy (which came back negative) he ruled out Celiac, leaving me very confused.
