Getting the rast results is certainly a roller coaster ride, that's for sure. You have the answers you were looking for (definitely allergies), but what do they mean? right?
Anyway, this is what i've learned abotu RAST results. This is from our pediatric allergist, kidswithfoodallergies.com and the Sicherer book that we read (last July when our kiddo's RAST came back).
Basically, the numbers don't mean anything in terms of HOW allergic he is. The numbers you're talking about are different from the range they use at our allergist, (ours go from 0-100, and have 6 levels), so I can't compare our numbers to yours, but basically what i've learned is that the numbers signify how LIKELY it is that your kid will have *a reaction*. Not WHAT reaction he'll have. Not HOW SEVERE the reaction will be. Just that it's either likely or unlikely that ANY reaction will occur.
And the threshhold for that is different based on the food. Like our kid's peanut was a 15, i think, and that was solidly in the "yes" category. If it goes until a 5, i think, then we can think about challenging him with peanut. And some people have an 80 on peanut. But even with his 15, my kiddo could have a full on anaphylactic reaction to even a small amount of peanut. Hasn't happened yet (thankfully!) but he hasn't had much, if any exposure.
So, basically, what you're saying with your kid's numbers is that there is a higher chance that he's allergic to nuts than to corn. And it's pretty darn likely taht he's allergic to dust mites, that's for sure!
The other thing you have to be aware of, is that if he was tested prior to any elimination/reduction of possible allergies (meaning if he was reactive), then his numbers could be higher because of that. Like those dust numbers. If you get him retested in 6 months, after you've reduced his dust exposure (with the hepa filter, mattress encasements, pulling up carpeting, whatever you're going to do...) then his dust numbers will possibly be WAAAY lower than they currently are.
In our case, kiddo's milk number at 7 months old was 114, and it technically only goes up to 100 (they have to do a special test to see how much over 100 it is). After a total elimination diet (bf'ing), and 6 months later, his milk number was normal-high, like 70s. All of his other numbers went down somewhat, as well. except the peanut went up a little, but you can't have everything, right?
Your allergist should really explain all this to you. i would ask for an appointment, maybe, to review the results? Our allergist said definitely to eliminate his allergens from our diet while bf'ing, but i know not all allergist think that way.
Check out Sicherer's book. It was awesome for us at the beginning:http://www.amazon.com/Understanding-...8329022&sr=1-1
