Patch testing vs. IgG testing?

[rhesp1212]

My DS was diagnosed with FPIES (Food protein induced enterocolitis syndrome) and has delayed sensativity reactions. The allergy specialist today wants to do patch testing on him in a month for foods that he has not be exposed to, so we know what we can add back into his diet. I have done alot of reading on IgG testing for delayed reactions also. Now I don't know what to do!! Would you do both of them, just the patch testing or just the IgG?

Thanks,
Valerie

I'd do the patch testing first... seems to be more accurate for FPIES.
