Hi, Everyone!
So, it's been a few years since my PN/Sesame allergic daughter has been tested, and we recently went to the allergist who suggested doing RAST testing. On the one hand, I would like to see if her numbers for PN/Sesame have changed, or perhaps look at the numbers of things we have avoided (like TN/Shellfish) and maybe consider a challenge (we are going on a major trip abroad this summer and knowing that perhaps TN/Shellfish were safe for her would not necessarily see her consuming them, but see me not as uptight about the possibility of CC).
HOWEVER, last time she did a RAST panel test (including environmental) she had a TON of false positives. This, along with the prohibitively expensive cost, is making me reconsider, despite the peace of mind it *may* give me. Ironically, when we did that test, some things that we avoid (TN/Shellfish) came back boarderline (class 0/1) and things like corn, soy, milk and wheat, which she eats on a regular basis, came back class 1/2! Anyone have any thoughts on reliability of RAST tests and whether or not they are worth the headache?
Thanks!
