My daughter and mother-in-law both just had ELISHA blood antigen testing done and Meridian Lab in Renton WA has added Duck Egg reaction to their A95 testings.
Both family members tested highly positive and to avoid duck eggs
When I had my testing done this was not an option for me so I am playing it by ear I suppose.
I suspect as with everything else each person is different and as long as one doesn't eat an egg every day, or maybe add it to a baked item where it is dispensed into the product. I freeze these types of foods so I can spread them out over a longer period.
I was just surprised that Duck Egg was being tested now.

I'm on the fence I suppose. Both Enterolab and these blood tests showed I was highly reactive to exact items. I'm glad I did the Enterolab though, it felt more scientific and very precise. The blood testing tested for many food items that have potential allergen response, (partly because those proteins were floating around in my blood an my immune system has taken offense to them) so it has been a useful tool too. I had over 200 items tested for from Meridian Valley Lab at a cost of $274, insurance wasn't an option with this testing facility, or at least my insurance wasn't and it had to be ordered by a Dr.
I don't have an Iga issue so my reactors had no problem showing up on either test.
It was nice to know I had potential to have reaction to some other foods if they were to be built up in my system again, but perhaps after time of healing the gut (so that proteins aren't just leaking into my blood anymore) I may be able to reintroduce some of the blood test foods with the exception of the ones that Enterolab deemed unable to for life.
This is my take on how I've interpreted the way our intestine goes about responding to allergen food types. If I'm out of whack I hope someone gets me lined back up again

I'll bet the Meriden blood test is for IgG or maybe even IgE antibodies rather than IA antibodies because IgA antibodies are usually not present at high levels in the blood. And if they're testing for true allergies, that has to be in terms of IgE and IgG antibodies.
The fact that both subjects tested positive to duck eggs (a relatively rare allergy) makes me suspect that everyone might test positive to that test, making it meaningless. IgE and IgG antibodies are usually of concern only for skin contact or respiratory considerations, not digestive effects (unless the subject has a problem with MCAD.

It is suspected that some of the hardest material known to science can be found in the skulls of GI specialists who insist that diet has nothing to do with the treatment of microscopic colitis.
Yep this is the statement on their website...so only IgE and IgG4 not sure what the 4 stands for....so perhaps for the sake of not knowing how most of the reactions are, the delayed end of things regarding this kind of testing may be what is most useful based on the foods in question. Ironically other foods that pose no problem have the potential to become a problem too....this would be a blip in time persay as to how things were going on at that moment, I would hope if I did the same blood testing now some of my results would be different because I am not eating the same foods anymore.
Diagnosis of Food Allergies Obviously immediate food reaction can be identified easily. However, delayed food reactions are much more difficult to diagnose. According to recent research, IgE antibodies cause immediate food reactions. Delayed food reactions are often associated with IgG4, a subclass of the whole IgG molecule. At Meridian Valley Laboratory, our food allergy test uses a combination IgE and IgG4 protocol. The test can detect both IgE and/or IgG4 allergic reactions. Thus both immediate and delayed food reactions can be detected.
