Hello, so I had a biopsy for a few different reasons. One thing that came back was a positive celiac disease result. But my blood work shows negative. What should I do with that?

Welcome to the forum. Can you tell us which blood tests you had done, and what the results were, including the reference ranges? 

A positive biopsy for celiac disease usually indicates that you do have it.

they tested tissue trans IGH… my results were 1.2 and less than 4 is normal.

So they did a tTG test, which was likely either IGA or IGG, but it was negative. It's too bad they did not do a full celiac panel, which is important as you could be IGA deficient, which will skew the IGA version of this test and could result in a false negative. You may want to ask your doctor if they can re-do the blood test and get a full panel done, and if you go this route be sure to keep eating gluten daily until all tests are completed:

      Any bad experience with King Arthur Gluten-free bread flour

      By Sanna King · Posted

      King Arthur Gluten-free bread flour contains wheat starch, but has had the gluten removed. According to the FDA, it meets the FDA's gluten-free standard of less than 20 parts per million (ppm) of gluten. Has anyone here tried to bake bread from this? If yes, did you have a reaction? Thank you in advance for your time and attention.

      Biopsy confirmed no celiac, low gliadin igg but high gliadin iga?

      By Gliadingoaway · Posted

      So i was eating tons of gluten my whole life until two months ago when i had high gliadin iga. At that time, i tested negative ttg and biopsy confirmed no celiac. I had h pylori and severe gastritis (no atrophy or ulcers).   fast forward today, i avoided gluten and had antibiotic treatment to erradicate the h pylori. I am feeling much better. A few days ago is when i tested negative for ttg, gliadin igg, endomysial iga. But i did test positive for gliadin iga. Pretty strange because i had gluten three days ago (accidently ate mac and cheese and fried chicken after taking the tests) and i feel fine

      Help needed

      @nanny marley, Are you having an endoscopy at the same appointment as your colonoscopy?  You said you have been going through testing for Celiac.  An endoscopy with several biopsies from the small intestine (after the stomach at the beginning of the digestive tract) is the gold standard for diagnosing Celiac Disease.  Celiac cannot be diagnosed by examining the large intestine and colon.  Colitis occurs at that end of the digestive tract.  I understand you are being checked for Colitis.  Are your doctors also going to do an endoscopy with biopsies at the same appointment to check for Celiac?  Even if you are too unhealthy to undergo a gluten challenge prior to an endoscopy, there are changes consistent with Celiac Disease that can be found by biopsy and microscopic examination.  Also get checked for nutritional deficiencies.  Many of your health complaints you've mentioned in other posts can be connected with vitamin and mineral deficits.
