Hi - we just did IgE and IgG testing for my 3 yr old DS. He does not have any super obvious GI symptoms but he had trauma at birth and has global delays. He is IgE allergic to eggs and mildly to a few other things. The IgG test came back with 'high' values for almost everything he currently eats. All the nuts on the list, all the beans on the list, and all the grains on the list were high, all dairy, and many of the fruits, a few veggies... I was shocked by all the high values. Especially given the general lack of GI issues (maybe I don't know what to look for?). He is currently vegetarian, so this is pretty problematic if we are really going to cut out all those foods. Interestingly none of the meats or fish scored high. I guess because he has never eaten those?
I guess my main questions are regarding how seriously do I take this test?
* Should we re-test with another lab? I've heard that the tests are unreliable and differ by lab. I don't want to overhaul our entire kitchen without being sure. We did the original test with Great Plains Lab which some people have expressed skepticism about (I'm not sure why).
* Is it ok to feed foods that were not tested? How can we get tested for all foods anyway, like kale and chard? They are not on the regular lists that I've found. But what if these foods are problematic too?
* If I cut out all these foods, and I don't substitute with odd beans or nuts that were not tested, it will mean that I have to feed him meat which I do not want to do unless it's absolutely the last resort. Is there anyway to stick with being vegetarian?
* Will it really be healthy to have such a limited number of allowed fruits/veggies/grains? I mean all that's left for grains is amaranth and teff... He was even 'high' for rice!
* Would it be better to go the other route and start with an elimination diet and start adding foods back slowly?
I would love any thoughts that would help me digest all of this (no pun intended)... I'll probably have more questions as I read more.
