My 3 year old took a peanut challenge test last week. Two years ago he tested positive for egg allergies (not peanut). Last year the egg allergy went down, but peanut popped up (3+). Blood test revealed no allergy to the peanuts. Doc suggested challenge test this summer. After 3 hours in doc's office, my son's only symptoms (or not) were coughing and complaining of a bellyache. Doc said throat looked fine and belly must hurt because of the chocolate (Hershey peanutbutter bar). Gave him Reeses Pieces and an hour later was coughing with runny nose and complained (cried) of bad bellyache. We're trying just plain peanutbutter, but he doesn't want to eat it.

Me again--we tried the peanut butter (well, sort of). He didn't want to, but I put some on my finger and tried to let him lick it, he got some on his lips and tongue, but quickly wiped it off with a napkin. 5 minutes later, he was pulling his tongue out of his mouth and scratching the outside of his throat. I asked him what he was doing and he told me his tongue hurt. His bottom lip got a little red and swollen (like a small blister onthe one side). Called the doc, he said to keep him off the pb and is sending us for another blood test.
Has anyone ever experienced anything like this before? Results?

coughing is a serious internal reaction sign.
I would question the safety of doing a food challenge if it is not in a hospital setting. with a intensive care bed avaliable.
please be very careful.

Your child had a reaction at the Dr's office. Cough is a definit indicator of an allergy and so is a belly ache. A cough and a belly ache means ANAPHYLAXIS. Those are 2 different body systems that had a reaction and that absolutely indicates anaphylaxis. I would immediately switch Dr's. Do not give your child peanut butter again and carry epi pens. RAST testing is not correct many times. Your child has an absolute allergy to peanuts. Be careful.

I had a scary experience on June 30. My 3 year old son's RAST (blood) test had come back as a "0" for the peanut allergy (he had shown an allergy 2 years ago on blood work and skin test, although he had never reacted). Since it was 0 this time, our doctor encouraged me to give him PB at home, saying they expected no reaction. I refused and brought PB to my next appointment.
The doctor (who I normally really like) was almost condescending about my fear to give him PB. She gave it to him and kept saying everything would be fine. Long story short, 5 minutes after giving it to him, her staff called 911. He began coughing, his lips swelled, and he vomited several times. The doctor was in absolute shock. She told me later having a 0 on RAST and reacting like that is almost unheard of. Of course, we now know it can happen.
In the end, she said we would do no further testing because it wasn't reliable with my son. She said he has PA for life and we should continue living like we have for the last two years.
In my opinion, your son reacted. Generally the next reaction is worst than the one before. If you do give him PB, make sure you have your Epi and I would do it in a hospital, even if just in the ER waiting room.
If I were you, I would see another allergist just to get a second opinion on what happened. My doctor was so confident in what the outcome would be of our oral challenge but she was wrong. Doctors are human and can be wrong. Sometimes we forget that as parents. I know I do!! A peanut allergy is not something a doctor should have you take any chances on.

Wow. I am taking my 4 yo DD to allergist on Wed. for a challenge. She was diagnosed almost two years ago with an egg allergy also by blood and skin and peanut popped up on the SPT also at a 3+. Never by blood. Then last year she tested negative for peanuts but positive to tree nuts so she has been peanut and tree nut free for the pat two years. She saw a new allergist almost 3 weeks ago and tested neg to everything but egg and turkey so a blood test was ordered with the same results as the SPT. So now we are having a challenge. After reading this I am a little nervous I have to admit.
I agree with keeping your son off of peanuts now. It sounds to me like a reaction. I hope you get some clarity and peace of mind. I think another opinion might be good. Best wishes.

lre, sorry for the previous post I misread. I would seriously go with a second opinion. This doctor overlooked what appears to me a very obvious reaction. I hate to think of what could of happened had a larger amount been consumed. At this point I could not trust this doctor anymore. Please let us know how the blood test goes.
Good luck on Wednesday KaraLH. I hope for the best for your dd.

Thank you. I am very emotional about this. It's very surreal to be in this place right now. I will let you know how it goes.

Thanks for everyone's input. Took son for blood test, awaiting results. Am being more vigilant in watching his reactions to more foods. I only kept him away from peanuts and peanutbutter, never looked for cross-contamination, etc. Hopefully he is not more sensitive now.
