I am new so bare with me please.

My ds almost 11 months was accidentally exposed to trace amounts of peanut butter, it happened at nap time so I got him ready for his nap and made sure there was no immediate reaction.

When he woke up from his nap (1.5 hours later) he had hives, a slight fever and wheezing (he had been wheezing for the past week but this was a bit higher pitched) anyway, I decided to watch him and see what happens. He was a bit fussy but seemed fine, the hives were gone by that night (this happened at 9am) and his wheezing was better by dinner time.

I told his allergist that he had a reaction to peanut butter and the allergist said "he tested negative so don't worry" my dh thinks that it must not have been the peanut butter since he tested negative. Does anyone have any links or information that will help me convince the allergist and my dh that this can be very serious?

Thanks so much,

welcome to the boards. You will find lots of useful information here.
My doctor told me that you cannot test for something that a child has never had. That it would be negative.
My son was diagnosed at 2 1/2 with his peanut allergy. My son never had peanut butter but had trace amounts in different things that he ate.
You could test your child with a small trace amount on the back of his neck or maybe on his arm.
When my son was tested at the doctors office he had a welt the size of a quarter if not smaller. I dont' know why my son never had peanut butter before that but I am thankful that he hadn't.
My suggestion would be to ask the doctor to do a blood test for the peanut allergy now that he has had a reaction, but before then I personally would keep him away from it.
If you child does end up with a peanut allergy I would also request an epi-pen Jr. In case he ever has another reaction.
best wishes,
Mom of Craig 11, allergic to amoxicillin, Drew 7, allergic to everything under the sun, and Kevin 4, only allergic to amoxicillin too.

Hi Mommy Meadow!
It sounds like your feeling very uncomfortable about this. Go ahead and insist on another test. When you're dealing with peanut allergy, it's better to err on the side of caution. If it comes up negative again, then at least you'll know for sure.
If your allergist is not helpful, consider switching doctors.
