talk to me about IgG results...

[chellebee]

We had DS tested--it was the US biotek test. He tested positive for egg, grapes, all gluten grains (barley, wheat, rye, spelt), soy beans and possibly: almonds, bell peppers.

He is currently off all dairy and corn, and was when the test was done. These would definitely not show up then in the test, right?

Do IgE allergies also throw an IgG positive? He has not had IgE testing.

In your experience, are all positives through IgG testing true? So...for example, if we find that after an elimination and challenge he is not reaction to soy, or only at a certain threshold, is it 'safe' to give him soy, or does it need to be avoided anyway from an immune perspective?

Thank you for your patience with all my questions. Definitely overwhelmed over here...

I'm not sure about that particular test. You might want to call/email the company and ask. We did the ALCAT test (tests for an inflammatory response to the food, not IgG) and they said you had to consume the food within 6 months for it to be accurate.

I don't believe that IgE results will show up on an IgG test, though there are some combination IgE/IgG tests.

Are you first eliminating everything, and getting him to baseline, and then testing each food to see if it's accurate? Is that what you mean?

Personally, I'd avoid soy as much as possible for a boy, but that's just me, whether it's "safe" or not. If it's safe for him, once in a while would be okay, but it's not like I would be giving him soy milk every day or anything.

It was this test. Apparently it uses ELISA.

Yes, I am thinking that I will need eliminate all to get him back to baseline like you said--and then test each food...

We don't do soy often anyway, it's the trace soy that I would have to be wary of.

[chellebee]

I should also ask--does anyone know what part of the food these tests are targeting? Like for eggs, raw? Cooked? Whites? Yolkes? Cause if it's egg protein, then maybe we're still good on yolks.

Perhaps a call to the company is in order...

Chellebee, I'd be interested in the answers to your questions as well. I'm waiting for my results for the same company now, and I've been wondering about the same things. Please keep us posted!

We had this test done, but it was the IGG/IGE version. For us, a few items were high for both IGG and IGE results (almonds, pecan, cashew, flaxseed, pistachio and filbert), but all the dairy items, soy and peanut were high IGE and no IGG. We had many fruits and vegetables that were high IGG and no IGE.

You might be able to add on the IGE part of the test after the fact. When we had it done, we were able to run the vegetarian add-on panel a week later because they saved some blood.

Egg whites and yolks were separate on my test. I don't know if they're cooked or raw.

Have you received a copy of your results? There will be a booklet with the test results that suggests a rotation diet. Because we had so many positives, we are eating several items that tested at a 1 or a 2 (out of 6). We are avoiding anything that is a 3 or above, and we're introducing new foods one at a time on a 4-day introduction schedule.

By the way, we had not been exposed to many of the foods that showed up positive for months, and some ever. So I don't think you need to have eaten the foods.

I will do my best! You can message me too if I forget to update. :P

BirthKathy--Thanks for your input. This is all very overwhelming and it definitely helps to hear what other people have done with the information.

I am requesting a copy of the test, my ND has them right now. I am also asking if we can add on the IgE. That makes the most sense to me right now.

That is interesting about not needing to be exposed to the foods for them to come up. I really don't understand this part! I was wondering if grapes was on our list because DS was eating raisins pretty much as the test was being done. It just seems so random! Found out today though that his grandma is allergic to almonds and bell pepper, so those turned out to be not so random.
