Wheat allergy - False positive?

[newmothermary]

Miles (13 mos) broke out in hives when he was around 10 mos after I gave him some scrambled eggs. No respiratory trouble but VERY itchy his whole face. I should've given him just the egg yolk but I didn't.

Anyway, that promptly an allergy test (blooddraw) for common allergens. So eggs turned up, along with shrimp, wheat and roaches.

I joked and told the ped I'll stop giving roaches.

The thing is, up to that point I've been giving Miles Cheerios, breadsticks, pasta with no visible problems. I read online somewhere that allergy testing for wheat (on los) can yield false positives.
Do you think its worth repeating the test? He doesn't eat a whole lot and what he wants has wheat. Naturally, If he is indeed allergic to it I would not give it to him. Same token, I'd hate to restrict his diet if it is a false pos.

Thoughts?

There is a 50% false positive rate with food allergy testing even w/older kids (who are more accurate). If he's eating them with no reaction I'd assume it was false positive. I'm assuming he's not got undetermined allergy issues like eczema that might be attributed to the wheat.

Having said that, he's allergic to eggs and wheat is another top allergen. I'd be a little cautious about giving it day in and out just for that reason. He's young enough that now is a good time to get him into alternative grains and foods. That said, readily available wheat free stuff is all crossed with nuts and that's even scarier. So unless you're up to shopping online and making stuff yourself I'd be hoping I didn't see a wheat reaction I think.

I'd only be concerned because with wheat there can be a lot of invisible damage that doesn't show up until it's very far gone. He was very young to test for allergies, anyway, so I wonder if you should retest and see what comes up. I would just worry, because i have two kids with wheat allergies that had been on wheat for a while, and it's SO much harder on them now that it is on my son who has always been off of wheat.

plus, if you get him used to wheat free eating now, it'll be easier for all of you in the long run. trust me!
