OK - we have our first appointment this Thursday with an allergist. The nurse told me that they will want to do a peanut challenge test? PLEASE tell me what that is? I dont like the word peanut anywhere around Matthew. Thanks for any input!

Well, I immediately think of a peanut challenge to mean the allergist wants to give your child peanuts to see if a reaction occurs. Have you seen this allergist before? Had a CapRast test? My child recently went through a milk challenge and drank milk periodically over three hours each time increasing the amount and watching for any reaction. We did this at the allergist office. My allergist stated he wouldn't give my daughter a peanut challenge even if the CapRast came out negative for a couple of years at least. Some kids have a negative CapRast test and still react during the peanut challenge. I would call he office back and demand more information.

I agree--call and find out what they're talking about. If the allergist wants to do an oral challenge without any previous testing, find another allergist. What I would want to have done would be a CAP RAST blood test. Since you KNOW he's allergic to peanuts (right?) don't bother with a skin prick test. A CAP RAST won't really tell you anything, but you'll have a number to compare to later. For other possible allergens that you're not sure about, you might want a skin prick to see. Positives are often false positives (not really allergic) but negatives are usually true.

Thank you! I did not even know what to ask for. I have not had any testing done because I knew that we had a severe peanut allergy. However, now that I have requested a 504 plan at school they want a letter from the allergist, etc.etc. .... which of course I dont have. We go tomorrow. Maybe I will go - but I will refuse to let them do that test. All Matthew has to do is be in the room with nuts and he will swell up. Thank you for your input and I will use it wisely tomorrow at our meeting.

Just wanted to point out about Ben`s mom`s comment that a negative skin test is usually true, and I do agree with that, but my daughter had a negative skin test to egg, and three days later when she was given egg the first time, she had a reaction so severe that I had to use the Epipen. I do agree, though, that a negative skin test is usually true, but you still really can`t let your guard down and you have to be prepared for a possible reaction even if a skin test is negative.

My son had a reaction to both eggs and peanutbutter and the prick test was positive. We then had the CAP RAST and it came back negative. They told us to keep away for several years though. So is he allergic or not??

I am going to print this page out and take it with me to the appt. tomorrow. So - if anyone else has comments or questions, please list them today. Maybe I can get some answers for all of us? Thanks again!
