My endoscopy biopsy looked exactly like something caused by Celiac disease but my blood test came back negative, what else could it be?

Two negative blood test for celiac disease is it possible to still have it and it be the cause of bone loss? How do i test and make sure 100%

There's no 100%: The labs are probably not totally sensitive / specific but they're pretty good. Have you had a biopsy? This is one to work out with your physician. Bone loss won't be the primary manifestation of celiac disease despite "pop" wisdom. "Low blood pressure" isn't an illness. A full workup, including some zebras like porphyria or other neuropathies, may be a consideration along with supportive Dr. ...Read more

If one tests negative for wheat blood allergy test, does this mean no chance of celiac disease?

If one tests negative for wheat blood allergy test, does this mean no chance of celiac disease?

No, definite chance: Blood tests for wheat allergy measure IgG and/or IgE antibodies to proteins in wheat (which may include gluten) but not everyone with celiac disease will have these antibodies. The best blood test is IgA anti-tissue transglutaminase. If you really want to rule out celiac disease you should get that test- but only after eating gluten!

In celiac disease, the body reacts to gluten (in wheat and gluten-like proteins in rye and barley) resulting in damage to the small intestine. This limits the intestine's ability to absorb some nutrients. Typically, people with celiac disease have loose stools, bloating, abdominal pain or discomfort, weight loss, poor weight gain ...Read more
