Hi Dr.
For initial testing you usually recommend OAT, CDSA and other general testing what about IgG food allergy testing. This test can help those who want to do the GFCF diet.What is your opinion about this test
Dr. Faiza
Dr. Faiza,
Yes, absolutely. I commonly do the Food IgG (finger prick) Test too. I mention that if a parent can only afford one test than the OAT is the best option, but certainly if more can be done initially than by all means do it.
