I too have recently been wondering whether the IgG test would show a sensitivity to salicylates.
My son tested positive for oranges/citrus bit negative to grapes and apples. Since he also tested positive to dairy and soy, his drinks of choice lately have been apple juice and grape juice, and his fruits of choice are apples and grapes.
Although tics aren't really an issue these days, behavior (rages) still were/are. They have gotten significantly better and less frequent, but not completely disappeared. I'm wondering if it's the continued consumption of apples, grapes, apple juice and grape juice, or if this is just the nature of my son. He can be very sweet, loving and affectionate, but he's always had a bit of a temper if he doesn't get his way. I hate to take away the fruits and juices at this point since his food choices are so limited these days...and I can't believe how good he is at sticking to his approved foods. We've been eliminating the foods he tested positive to for about 6 weeks now.
Any thoughts?
