Can I have celiac disease even if a skin test showed negative for wheat allergy?

Can I have celiac disease even if a skin test showed negative for wheat allergy?

Definitely: Contrary to common belief, celiac disease is not a "wheat allergy". It is the body's abnormal immune reaction to gluten, but it is not mediated by the classic antibody that mediates allergic reactions. Skin test to wheat is not the right test for celiac disease. Skin test negative or positive to wheat does not rule out or confirm celiac diz. If u r concerned, ask ur doc for the proper blood test. ...Read more

Can I have celiac if a skin test was negative for wheat allergy?

Can I have celiac if a skin test was negative for wheat allergy?

Yes: Celiac is due to an immune reaction to certain components of wheat protein, gluten/gliadin, but is not due to allergic antibody (ige) to wheat, so skin testing is negative in celiac. Certain blood tests showing immune reactions to certain intestinal enzymes, e.g. Tissue transglutaminase (ttg), are positive in celiac disease. Consult a gastroenterologist. ...Read more

Test positive for celiacs if you have been on a gluten free diet for 2 months? Is it worth it to go back on gluten to get a positive test result?

No: Your celiac problem is not going to go away so why would you want to make yourself sick again? Remember that some people may not totally recover until after several months off gluten product. However if your symptoms do not improve after 3 or 4 months, you need to evaluate the diagnosis or consider another diagnosis since the presence of celiac does not preclude other illnesses. ...Read more

Keep on keeping on: Regardless of the test, if you feel better there has to be something about gluten-containing foods that doesn't agree with you. Don't think too much about this. Do what makes you feel better. ...Read more

I had an fecal occult blood test that is positive, waiting to see a GI Dr. This morning my BM had some visible blood in it.  Should I get help sooner.

No: Your life's only in danger if you develop black tarry stools, vomit blood, or go into shock, all of which will be obvious. Finding visible blood after a bowel movement, especially a difficult one, doesn't increase the urgency of a search for cancer, which is what the principal concern is in this case. Best wishes. ...Read more
