Hi all!

I'm new to this site and I posted a question down under the doctor heading too.

I've known my son has a PA since he was about one, due to a couple of reactions to pb. We only recently had a RAST test done because he was starting school and they needed the documentation. The doc sent me the results of the test in the mail, but has been no help in interpreting it for me. It's obvious by the numbers that he's highly allergic to peanuts, but there's a lot of other things on there too.

The ped won't give me a referal to an allergist (see post below under doctors for more details about that), so I feel like I'm on my own to understand this. I've heard people on this site refer to "class 4 or class 5", but it doesn't say any of that on the test result that I have. It just says >100 and also something 5450%??? I don't know what these values mean except that they are way higher than any of the other things on there (wheat, soy, eggs, etc... all of which he is allergic to too).

Knowing this stuff isn't going to change how I deal with this. I consider it a life threatening condition and am taking it very seriously... no matter what the numbers are... but I've heard you guys using these terms and I'm curious about it.

Thanks!

Jessica, mom to Julian - almost 4 with PA

I don't have my son's labs handy, but he too measures >100 and is considered category 6 (the category was listed next to the number on the report). I hope this helps.

The Cap RAST is only scored from 0 to 100 (which is then categorized 0-6) so the test results only show >100.
I read your other thread. Besides giving the test, my allergist hasn't provided me with any new information. If your ped continue to refuse, just research and get info through AAAAI ([url]http://www.aaaai.org/[/url]), FAAN [url="http://www.foodallergy.org"]http://www.foodallergy.org/[/url] and especially Peanutallergy.com
And you can call Dey and get free Epi pen trainers and a video to help ease your anxiety.
Glad you found this board! Threads here will give you much more than you can expect from an allergist alone [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]

Cutey...I would insist on a referal to an allergist. I think all these children with serious food allergies should be seen and properly diagnosed by specialists. If your current ped won't give you a referal and won't even take the time to explain very complicated yet critical aspects of your child's diagnosis and condition you should get a new doctor. Is your current ped giving you perscriptions for epipens and proper management information? This whole business is anxiety provoking enough, and you are entitled to as much peace of mind as you can gather. It appears that different doctors have different ranges of expertise on food allergies and different degrees of compassion. Your first task should be to find an allergist who you trust and who will answer all your questions. I have discovered that in all things medical, parents really need to advocate for and micro manage their children's care. It sound like you are already doing that! Take Care!

Thanks everyone for your replies, it was very helpful. To answer the question about the epipen, yes, I have a rx for it... I think I need to get more though. I carry one and the school has one, I'd like to have a couple more.
I've done some research on the net on food allergy specialists and found a couple in New Hampshire, which is not too too far from us here in Maine. It might be worth the drive and I'll push the issue with my ped some more... or find a new ped... easier said than done with Medicaid.
Thanks again!!
Jessica
