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

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

Absolutely: Celiac disease is not an allergy, so the wheat allergy test is worthless here. There are blood tests that indicate the possibility for this condition, which is a problem of digestion. The best test, unfortunately, is a biopsy. ...Read more

The reaction can present with typical symptoms of hives, respiratory symptoms (cough, wheeze, shortness of breath), GI symptoms (abdominal pain, vomiting), swelling, loss of consciousness, and can be fatal. Symptoms typically present within minutes to a couple hours ...Read more

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

Is it possible to have celiac if a skin test showed negative for wheat allergy?

Is it possible to have celiac if a skin test showed negative for wheat allergy?

Yes: A wheat allergy test is not the same test as a celiac tissue transglutaminase or endomysial antibody test. And even if those tests are negative, a small intestinal biopsy is needed to ultimately make the diagnosis of celiac. ...Read more

Is it possible to have an allergy to gluten without having celiac disease? My cd test came back negative

Is it possible to have an allergy to gluten without having celiac disease? My cd test came back negative

Wheat allergy: It is possible to make allergic antibodies (ige) to wheat and gliadin. This would be called wheat allergy and not celiac disease (cd). Blood testing (rast) can diagnosing this problem. These is no accurate blood test for cd however, persons that show the presence of certain igg and IgA antibodies against deaminated gliadin or tissue transglutaminase are more likely to have cd. ...Read more

Genetic blood work done for celiacs- one gene positive for celiacs another negative. I have lost 30lbs in 5m, is it highly possible I have celiacs?

Genetic blood work done for celiacs- one gene positive for celiacs another negative. I have lost 30lbs in 5m, is it highly possible I have celiacs?

Get checked out: Only a small % of people with the genetic markers develop celiac disease. However any weight loss of 30 lbs without an known explanation should be vigorously evaluated even though your symptoms may be suggestive of gluten intolerance. I presume that you are anorexic . ...Read more

I have a barley allergy confirmed with a blood test. Was tested for wheat, rye. Is it common for barley allergy to "standalone" or similar substances?

I have a barley allergy confirmed with a blood test. Was tested for wheat, rye. Is it common for barley allergy to "standalone" or similar substances?

Barley allergy: Yes barley allergy alone is actually very common. I usually see 6-7 people a year with this allergy. Usually it causes itching alone (which can lead to eczema), recurrent urticaria ( hives) and/or intestinal cramping with diarrhea. The hard part with avoidance is that many brands of flour are a wheat/ barley mix. So this calls for a lot of label reading and avoidance of things made with flour ...Read more

If I was tested for celiac disease when I had an EGD does that mean I have zero problems with gluten? Or could I still have a sensitivity?

If I was tested for celiac disease when I had an EGD does that mean I have zero problems with gluten? Or could I still have a sensitivity?

Complex issue: You can have evidence of a gluten intolerance (increased transglutaminase IgA and gliadin-transglutaminase Complex IgA) picked up on by specialized labs.This abnormality can be found in the absence of a positive biopsy for celiac which is more reflective of the severity of the problem.Although living gluten free can be hard, for many it is worth the effort. ...Read more

I currently have a wheat allergy. I was tested for celiac, and it was inconclusive. Is there an over the counter antihistamine i could try?

I currently have a wheat allergy. I was tested for celiac, and it was  inconclusive. Is there an over the counter antihistamine i could try?

Hard to say: Wheat is composed of a complex group of proteins and many have selective responses to various components.If you have a simple IgG reaction, it may be of minor importance.If you have TTG-IgA to components of wheat like the gliadin or gluten, your past avoidance of wheat may have made testing unreliable.Continues intake could aggravate issues that antihistamines would not prevent. ...Read more

If I took a sweat test for Crohn's diease and tested positive, does this mean I have crohn's?

If I took a sweat test for Crohn's diease and tested positive, does this mean I have crohn's?

Double check: I know of no sweat test for crohn's disease. Generally, crohn's is diagnosed by a colonoscopy and biopsy, or a video capsule endoscopy. Double check what you have been told, as there is a sweat test for cystic fibrosis. ...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
