Let me add to the post I just made: Twice, I had an IgG Standard Food Sensitivity Assay through Immuno Laboratories. The first time, I reacted to 20 foods. The second time, I reacted to 34 foods. In the end, I found these results to be useless and inaccurate. I understand that Dr. Osborne recommends ELISA/ACT testing through Biotechnologies, and I do understand that all the types of immune reactions are tested (not just IgG). However, because of my previous experiences, I am doubtful of the effectiveness of blood testing. Still, I wonder if I should be tested, in case I have any new food allergens that I am currently unaware of.
