Thank you Glenn for your reply.

Do you think that it would be wise if i request another test, not using the "deaminated", just before considering the biopsy?

I am wondering if one is celiac, can she/he still absorb nutrients? I ask this because i am taking Vit B12 (just an example) and my blood shows the max number after 3 months, which means that I absorb VitB12. I am not sure if my thinking makes sense, just thinking aloud.

I have a strong suspicion that I have Sjorgren's, though, all my tests are negative. I have all the dryness of eyes, mouth, throat and nostrils. AND I have fibronodules in my lungs. I doubt that even my neurological symptoms may also be caused by the Sjorgren's.

When you use the B12 5mg daily on an empty stomach as we do here, you bypass the need for intrinsic factor. It is passively absorbed therefore.

It seems that the gluten intolerant people may have damage to the system that utilizes intrinsic factor for transport of cobalamin from animal food source protein.

Not all people with gluten intolerance get GI inflammation.
What happens is that the leaky gut (enlarged Zonulin channels),
allow the gluten peptides to enter the blood stream where they don't belong, and they arouse antibodies against nerve tissue.
From reading the gluten sites and forums, there seem to be people who don't have the diarrhea, gas, bloating, and the converse constipation all equally.

The Celiacs with the genetic markers, seem to be intolerant of many foods and have severe GI symptoms, however. They have the most inflammation in the intestine, and hence nutrient absorption there can be reduced. This includes many vitamins
and minerals, not just B12.

If left untreated celiac disease can lead to some serious problems: Anxiety and depression... So it could be complications of untreated celiac.
