Skin prick test reaction

[Megn93]

Hi Everyone! I have not been diagnosed with celiac but I am planning on doing that soon as I am able to. I have stopped eating gluten and stopped having GI issues. I also stopped having dairy because that was causing problems as well. 

 

My my question is can you get a different reaction to a skin prick test besides the wheal? I got tested for ragweed and bananas (because I ate a banana recently and my mouth got all tingly) but no reaction showed up on my arm. I did, however, feel that my mouth got itchy. Then I came home and ate a banana and the same thing happened. I asked the allergist if I would have experienced any other reactions besides the wheal but she said no. I feel like she wasn’t taking me seriously so I didn’t tell her my mouth was itchy. Is it possible it was from the skin prick test? I also just tried to have some cucumber and that made my mouth itchy too, which, when I looked it up might be because the cucumber is in the ragweed Family. I don’t want to be overdramatic but I’m scared to eat these foods now. Is it possible the skin prick test was a false negative? Was the itchy mouth a reaction? I got the reaction from the banana Not the ragweed and I used a real banana because she said the extract isn’t always strong enough. Help!

It is possible to have systemic reactions from skin prick tests, but they are usually happen along with a positive skin reaction.

Here is some info about ragweed/banana and itchy mouth.

Just keep in mind that celiac disease testing requires you to be consuming daily for 8 weeks or so before a blood draw.  They are testing for antibodies and not an allergic reaction.  It is possible to also have an actual wheat allergy.  

Allergy testing (IGE) is not always accurate.  For example, I wheal up for horses and cats.  But I do not worry about exposures.  I still ride horses and pet cats (but I do not live with them on a daily basis).  Not all allergies lead to anaphylaxis.  I think you should research more and talk to your doctors.  You may be worrying too much.
