In 2005 I went to a Allergy Doctor,manly because I wanted to get on Armour Thyroid. He took a Stardard Food Panel: lgG/lgE with US BioTeK`s Labortories.
IgG antiodies may be associated with Delayed-Onset Hypersensitivty Reactions.
IgE antibodies may be associated with Immediate-Onset Hypersensiitivity analysis.
My food panel showed the degrees of sensitivity .like (NO REACTION, LOW, MODERATE, HIGH.) in all foods. I was had many on HIGH. I needed to make the duck eggs work for me,because I needed the nutrition. I have no reaction except that they do give me body odor. Under the arm pits and privates. So I need to tend to that often. I think too that the duck egg is detoxifying . Since it is rich is good fats, the liver and gall bladder still have to process it. An allergy problem and a sensitivity are two different things. My ducks eat clover etc. that makes their egg yokes orange. I have a friend that will not eat them just bexcause they are dark orange. His problem is a mental issue. My Husband prefers chicken eggs because Duck eggs make him woozy . He also has bad food choices that would make me feel woozy. Some one on this Back Yard Chicken Group did get his allergy teste for duck eggs and they did find that he was indeed allergic to them. I have had health issues and needed to try.
