Ok, I finally got a referral for an allergist. My ds was tested at like 16 months for food allegies. He tested positive for milk, soy and peanut from a RAST test. Anyway, He hasnt been to an allergist since then and we have moved. So at his 4 year appointment this morning his dr. gave me a referral so I can have him retested. So I called and actually got an appointment for thursday morning.
Should I let them do the skin test on him? Should I specify that I want a RAST test. Does it matter?
Thanks

whenever we do testing, I do both(skin and blood) it is to helpful to compare the results of both together(so hopefully no false poisitives squeek through). Good luck!!

Since DS has had an anaphylatic reaction to peanuts, he was advised NOT to have the skin prick test. The skin prick test counts as an exposure, and there have been serious reactions to it. (That is why the Xolair trials were stopped).

I've never been clear about this question. I do know that when DS was 3 (before ana reaction) I asked them to add peanuts to SPK. The allergist told me no test because we could expose him (he had never eaten peanuts or tree nuts) and that he should avoid until 5yrs. due to his allergy history (environmental).
After the ana reaction, the allergist did scratch test to confirm what caused the reaction. He was tested again when he was 6 after a low number from RAST.
I do not believe that my allergist would have done the test if there was a threat to my son. He is very cautious and careful with his patients. But, I've heard from other posters here to avoid the skin testing due to exposure?
I don't even know if there is a difference in Skin prick and scratch testing? I'm gonna look that up.

I am curious about this myself- I think my daughter had scratch testing- her skin was scratched with a lancet

The skin prick test would be dangerous for a peanut allergy, but the scratch test is very minimal, isn't it?? It just scratches the surface as opposed to being injected into the skin...I've tested ALL my kids every year with the scratch test and the blood draw. I've seen allergies come and I've seen some go and some stay.
We've never done the prick test, but with the scratch tests, I've never been told it's a bad idea.....maybe just my 2 allergists??
