I recently had my DS (4) and DD (23 months) tested for allergies. (Blood draw). DS had already had one test done at his 3 year well child visit and it showed mild allergy to milk and egg whites. This time he was tested for a whole range of foods and environmental stuff. I will just tell you what the lab results say and you can tell me what (if anything) it means anything to you. (Lol!)
For cats and dogs he tested >100.00 (class 6- not sure what this means?). For these he prescribed Epi-pen Jr- he does have severe reactions to being around dogs and cats- we just didn't realize that his allergy was the highest possible- (according to the Dr.) D. Pteronyssinus (I think if my Google search was correct, this is just the scientific name for dust mites) also tests out of range at 0.41 (class 1). For foods, egg whites is 0.44, cow milk 0.53, corn 0.39 all of these are class 1. Soybean came back at 0.82, class 2. (Does this indicate a more severe allergy?)
Here's the reason I'm asking for help w/these results: we had a follow up meeting w/the Dr. (our new pediatrician- according to the bio on his website, he has a "special interest" in allergies- which is part of the reason I felt that meeting w/him would be promising) and basically he glossed over every result except the pet allergies. He didn't bring up the D. Pteronyssinus, or the corn, and really didn't address the other food allergies. I was looking at my copy of the results later on and noticed the soy being higher than the milk or egg whites- which of course I already knew he had an allergy to. (With milk and egg whites, he scratches a lot, and I find scratch marks all over his back and bottom, plus he gets loose stools- once we eliminated those foods, these issues cleared up- usually if he has anything w/hidden dairy or eggs like cake or other pastries, the symptoms return, but I've noticed they've diminished lately). I've never noticed any type of reaction from him eating soy (or corn) but of course those are in pretty much everything unless you make everything from scratch (which I do a lot of, but I'm not all the way there yet :-)) But other than the everyday stuff that soy and corn is hiding in, his diet is not really rich in either of those things. In fact, I make it a point to mostly avoid soy anyway. (Though I have recently been buying him those Z Bars (cereal bars) lately and I know those contain quite a bit of soy- and I noticed behavior issues sometimes when he eats them).
I called the doctor later on to ask for clarification about the things I was unsure about. He told me the D. Pteronyssinus "means nothing" and I said "well what is it?" and he said "it's nothing". (Ugh!) And I asked the things about soy and he basically said "it won't bother him" and I said "well if he eats it, won't it irritate his gut?" and he said "he'll be fine". (Not exactly reassuring). I guess if he's right, then he's right, but somehow I don't think those results "mean nothing". :-/
So, does this mean I need to be more vigilant about eliminating soy (and corn)? And also, with regard to soy allergy, do I need to look out for soy lecithin and soybean oil?
The other thing is, DD only tested positive for cow's milk allergy. (0.42, class 1). That kind of amazed me, because when she was an infant, I had to eliminate milk, soy, eggs, wheat and a couple other things from my diet or else she had constant spit up, blood in her stool and more. The only allergy I suspected w/her was milk, egg whites and possibly wheat (she does eat this occasionally, but I notice loose stools if she eats a decent amount of it). I gave her something w/butter in it recently and she got a rash around her mouth- same as her brother used to get at her age. She eats egg yolks several times per week and does really well with that, and I was uncertain about the egg white, so I haven't introduced it yet- but maybe now I'll try. I guess my question there is, are these tests accurate at her age? (I actually wonder how accurate they are at any age, as I've heard different answers).
TIA for any feedback!
