Re: RAST test and IgG IgE food panel

Hi:

Can someone explain to me the difference between a RAST test and an IgE/IgG

food panel allergy test? I know the IgE IgG test is a blood test. I had

this done and it was explained to me that the IgE is related to immediate

reactions while the IgG is related to delayed reactions. I showed high

reactions on both IgG and IgE to milk products and cut them out for 7 weeks

with no result. My doc. told me that this test was very controversial and

apparantly not accurate in my case. But I am confused how this test differs

from the RAST test and if I should get the RAST test done. These tests seem

very confusing when one already has skin issues. I also had the skin prick

tests which showed positive reactions to many foods which I then eliminated

for 3 weeks with no change. Dr. said that 3 weeks was long enough to try and

I just had a false positive reaction. If anyone can fill me on on the RAST

test I would appreciate it. Thanks. Molly
