My son was skin tested at about 18 mos. due to his eczema. He tested positive for peanuts and was given an epipen prescription. He had eaten peanut butter and other products containing peanuts prior to the testing and never had a reaction. Now of course we have to avoid peanuts and carry the epipen everywhere. I am just wondering if anyone knows of any way that we can find out if he really is allergic or not. It is difficult to deal with this--especially if if turns out that he is not allergic. I pray that he is not and I would like to know for sure before he goes to preschool because I am a nervous wreck about all this. The Dr. said that he may or may not ever react, but the only way to know for sure would be a challenge. That terrifies me too. Has anyone else had this experience????

Welcome to the board! There are several other people here whose child tested positive but has eaten peanuts before without reactions.
I can not help you in this because my son has reacted but I just wanted to let you know that you are not the only one scared and that it gets much better with education.

Cartersmom, I am in the same situation as you. My son had a reaction to walnuts, then was tested for everything and came up positive for peanuts and almost every nut. He had eaten peanut flour granola bars, tasted peanutbutter (at least on his tongue) and picked peanuts off deserts and eaten them (he never liked peanuts.)
Technically, if your son ate peanuts and didn't react, he's not considered allergic. I don't see any point in an oral challenge because he's already had one--he's eaten the stuff. I think there is a statistic somewhere on one of the recent topics that says only 50% of people with positive skin prick tests actually react.
My feeling is that, although my son may not technically be allergic, he is an "allergic person" so to speak. He has had eczema, hayfever, reacts strongly to mosquito bites, dog licks, etc. I feel that he has the potential to become allergic even if he isn't really allergic now. I would never feed him peanuts unless and until he someday tests negative (and even then maybe not.) However, I do have a more relaxed comfort zone than others because of this.
For more, see an old thread of mine under "is my son allergic or not" and something along the lines of "tested positive but never reacted." I emailed FAN about this and I think I posted the response in one of those threads.
We're so lucky our kids have never reacted, but it is a little weird to be so worried and not know if we should be! In the coming months, you will settle into your comfort zone.

It is my understanding that skin prick tests can show a positive-like reaction in people with eczema, even if they're not allergic. My son is definitely PA (he's had reactions). His skin prick test included a saline "control" prick - which he reacted to with a 'positive' bump. He has very sensitive skin. He's not allergic to saline, of course. I'm pretty sure there is a thread floating around here somewhere about eczema and skin prick tests. I think I'd try a blood test next. Good luck!

[b]Lam, I was excited to hear about the possibility that my son's skin prick test result to peanuts may have been due to his sensitivity..he suffered with horrible eczema from birth until allergy tested( prick test) at 5 months. They told me the measurement on the peanut one was borderline, but I should treat it as if positive. I would never give my kids any peanut product under age 3 anyway, so he has had no reactions I am aware of. He has reacted (mainly eczema) to other foods he tested positive to, as well as some new ones, but I really was dreading the peanut. Maybe there is some hope! thanks, Jen[/b]
