I'm not sure Carefulmom is posting here anymore - she mentioned she was dropping out in another thread.
I can tell you where our pediatric allergist sends his tests though - Mayo Clinic.
Carefulmom and I had a whole exchange on this in another thread. I'll see if I can find and raise it for you.

Thanks! I wonder if Quest is considered reliable. It is frustrating but not necessarily surprising to hear that RAST scores could vary greatly. I hope DS's are fairly accurate.

Is that REALLY true? I have never specifically ASKED my allergist which lab she sends for the RAST test, but I assumed that since she is a very well-respected doctor in a large children's hospital that she knows where to send them.
I would think that we would have differing numbers all over the place if different labs gave different results.

The allergist we see at the University of Michigan sends the blood to two different labs, one is in California and the other is at the Mayo Clinic. In our case he wanted to see a breakdown of specific proteins for milk and egg and each lab was able to do one but not both of these tests.
Ben is allergic to multiple foods, we do not have any nuts or nut products in our home but we do have other allergens. I do make all of his food seperate from the rest of the family and even though his allergy to milk is pretty low I would not give him anything that had been cooked with a dairy product.

i dont peel cheese off pizza but i dont worry about cross contamination to a great deal with my sons milk allergies. although i know he is still allergic (very positive skin test). he does not react to small amounts so I dont worry about it too much. that being said i am very careful about peanuts and would never treat it that way..
