Tissue Transglutaminase Ab IgA Retesting

About 8 months ago I was tested for Tissue Transglutaminase Ab IgA and scored over 250.  I still have been having problems so I asked to be retested yesterday and scored 22.3, which is still higher than the 12 that they compared too check if you have celiac disease.  Does this mean gluten is likely still getting into my diet?  I think I've been very thorough removing gluten, checking things like lip balm and others.  I've basically been following Dr. Gundry's Plant paradox diet, with no lectins, no sugar and no antibiotics.  The food I don't make myself is things like Dark Chocolate and a few sauces like a gluten free ranch dressing I'm using, so I was a bit surprised to find out I was still over range on this test.  The only other place I can be getting gluten is from medications like Tylenol.  Does anyone have any experience with retesting results?  Maybe it just takes a long time for the scores to go down?  My diet is already very restricted, so I'm reluctant to reduce it even more if my score doesn't likely mean I am still getting gluten in my diet somehow.

It took a full year for my number to lower into the normal range.

It can take a year or longer for antibodies to normalize.  So, it sounds like you are on the right track.  Remember, the antibodies testing was designed to help diagnose celiac disease.  It was never meant to check for dietary compliance.  However, it is the only non-evasive “tool-in-the-toolbox”, so doctors use it.

OK thanks a lot.  I was a bit worried.  They recommend that they should be rechecked once in the first 3-6 months and then after a year and yearly after that, so I was concerned that maybe they were supposed to go to normal after 3-6 months.

Doctors are just looking for a downward trend at the 3 to 6 month mark.  I can tell you that my DGP IgA was very elevated when I had a repeat endoscopy/biopsies that revealed healthy villi.  My GI was as perplexed as me.  So, use it a just one tool.  Look at other health markers (e.g. in my case, hemoglobin) or vitamin/mineral deficiencies or how you feel  to help you determine your healing.

      Could this be a new intolerance

      Unfortunately, the development of celiac disease usually is not an end in and of itself. It usually brings along friends, given time. It is at heart an immune system dysfunction which often embraces other immune system dysfunctions as time goes on.

      Thanks so much for the responses. I will urge him to go for further investigation. To be 48yrs old and develop a new allergy.. ugh, As if celiac disease isn’t enough!

      This does not seem to be an anaphylactic response but I agree it would be wise to seek allergy-food sensitivity testing. You might look into ALCAT food sensitivity testing.

      Could this be a new intolerance

      @Celiacpartner, I agree with Scott. We have a food festival yearly in the town I live in, with artisan food stalls everywhere. I spoke to the owner of one of the artisan burger stalls, enquiring if the burgers were gluten-free when I said I was Coeliac ... he said he had a serious anaphylactic allergy to fish himself. He possibly carries an epi-pen or...

      Could this be a new intolerance

      After years of stable management, developing new symptoms to historically safe foods like nuts and fish strongly suggests a secondary issue has developed. It is highly unlikely to be a new gluten issue if the foods themselves are certified gluten-free. The most probable explanations are a new, separate food intolerance (perhaps to a specific protein in certain...

      After years of stable management, developing new symptoms to historically safe foods like nuts and fish strongly suggests a secondary issue has developed. It is highly unlikely to be a new gluten issue if the foods themselves are certified gluten-free. The most probable explanations are a new, separate food intolerance (perhaps to a specific protein in certain nuts or fish) or a true IgE-mediated food allergy, which can develop at any age. The symptoms you describe—cramps and the urge to vomit—can be consistent with either. It is crucial he sees an allergist for proper testing (like a skin prick or blood test) to identify the specific culprit and rule out a serious allergy, as reactions can sometimes worsen with repeated exposure.
