I am not so new to PA, but still learning so much. I was so naive when my son was first diagnosed 2 1/2 years ago. And, I'm learning so much here.
I see lots of mention of the RAST test, or RAST numbers. I'm not sure if my son has one (a number, that is). Does the number indicate the severity of the allergy?
When we were first aware of his allergy, he had a "skin prick" test at the allergist. At the time, we received a piece of paper with a bunch of allergens on it, and next to peanut (the only one tested) it has a 4+. Would that be his RAST number, do you think? Of course, we've had to change allergists since then (thanks to an insurance change), so it wasn't our current allergist who did the initial test.
Anything you can explain to me about RAST would be most appreciated. Thanks!
