Positive Biopsy Negitive Bood Tests?


Edges12

Recommended Posts

My 6 year old son (adopted-no real family history) Had endoscopy last week for abdominal pain, vomiting. He was found to have reflux, gastric spasm, and espophagitis. The biopsy also showed increased lymphocites in his intestional tract and villa atrophy. the GI said he felt he had Celiac and ran a celiac panel and some other Immune Tests. He just called to say that the tests came back normal and he does not have celiac. He is not sure what he has but did not reccommend any other testing. Meanwhile our son is down 7 lbs in 2 1/2 weeks and continues to do poorly. The pediatrician is still doing research.

So .... could he still have Celiac and have negative blood tests? any other thoughts on what we should do, tests etc. When he had the blood work done he had been sick for 12 days and had been on almost a full liquid diet. I asked the GI if this might effect the results and he said no. Any thoughts?

There definitely can be for a few reasons: If you don't eat gluten for at least 3 months before testing, if you're IgA deficient, if the lab messes up, etc. It's definitely possible. Prometheus is a good lab to send the blood to. And some people just test negative but respond very well to a gluten-free diet....or get a negative blood, but positive Enterolab result.

What blood tests were run?

Some blood tests that are done are not as specific as others. Prometheus labs as mentioned is a reliable lab for celiac testing. He also should get a gene test done.

Enterolab might be a good option they test for malabsorption, gluten sensitivity, genes and so forth.

He has the symptoms and the damage it sounds to me like he has celiac. Some people have negative bloodwork but still have it, some people have negative biopsies and have it.

He could also have been IgA deficient. Alot of celiacs are and that can make otherwise positive tests, negative.

I think you should find a doctor for him that knows alot about celiac and symptoms and so forth.

Good luck and your family will be in my prayers.

I am not postive which labs were run. He just wrote Celiac Panel and then also added IGA,IGM and one other plus a test for lymphocites in the blood (which is not back yet) He did not read me the results just told me they were fine. Our son was certainly not gluten free for 3 months but was for the 12 days prior to testing due to his stomach problems and inability to eat. The tests were done through LabCorp

I asked because the tests under the celiac panel hold different....weight w/ a pos. or neg. reaction...with one test a positive might be nearly definite and with another, it might still make celiac disease questionable.

Endoscopies can easily get false negatives but have very reliable positives. I'd go gluten-free on that.

      How long have you been strictly gluten free? Certainly, it would be good to look into vitamin and mineral deficiencies and supplementation. The B vitamins, magnesium and D3 are all very important to neurological health. Unfortunately, it can be difficult to reverse gluten-induced neurological damage damage if it has gone on for a long time.

      Thanks Trents I'm strict with my gluten-free diet now. I just don't feel any better. I'm going to get tested for vitamins and minerals to see if I need some supplements. For sure I got some damage that doctors call Menier's and the only way they treat it is with medicine that does damage my body more than it helps.

      Thank you Scott for your helpful response! Based on this, would you say someone who is on a gluten-free diet - but not strict about cross-contamination and occasional cheating - and tests negative for tTg-IgA while having normal total IgA is not likely to have celiac, even if they have been 'gluten-free' for years?

      That’s a really insightful observation about antibody testing and the gluten challenge! You’re absolutely right that antibody levels can remain elevated for months or even years after going gluten-free, especially if there’s ongoing cross-contamination or occasional slip-ups. The immune system doesn’t reset overnight—it can take time for antibodies like tTG-IgA to normalize, which is why many doctors recommend waiting at least 6–12 months of strict gluten-free eating before retesting. For someone who’s been gluten-free for less than two years or hasn’t been meticulous about avoiding cross-contact, there’s absolutely a chance they’d still test positive, since even small amounts of gluten can keep antibodies elevated. This is partly why the gluten challenge (where you eat gluten before testing) exists—it’s designed to provoke a measurable immune response in people who’ve been gluten-free long enough for antibodies to drop. But you raise a great point: the challenge isn’t perfect, and false negatives can happen if the timing or amount of gluten isn’t sufficient to trigger a strong antibody response. This is why diagnosis often combines antibody tests with other tools like genetic testing or endoscopy. Your question highlights just how nuanced celiac testing can be! For people with celiac disease hidden gluten in their diets is the main cause of elevated Tissue Transglutaminase IgA Antibodies (tTG-IgA), but there are other conditions, including cow's milk/casein intolerance, that can also cause this, and here is an article about the other possible causes:

      Thank you for your response! I have considered starting a food diary in the past, I suppose this is as good a time as any to start.
