Before I post explaining what I am learning about the components of certain allergies, let me first explain how allergies are classified. There are six levels/classes associated with allergies. When you have a blood test done, it is looking for the level of immunoglobulin (IgE), an antibody in the blood. These substances are created by the body as a response to certain allergens. TJ’s immune system detects and labels all of the foods that he is allergic to as harmful invaders, thus attacking them.
If you are not allergic to the food, you are a class 0. The table below has the classes based on IgE levels. The greater the amount of IgE present in your body for a specific food, the greater the risk of a more serious reaction, such as anaphylaxis. From what I am told, a high level does not mean anaphylaxis will definitely happen. Instead, there is a higher risk of it. Sometimes though, allergy testing even through blood is inaccurate.
Despite all of the allergies, there are many foods that TJ tested as a class 0 for. These include buck wheat, corn, rice, beef, chicken, turkey, apples, bananas, raspberries, blueberries, strawberries, pears, peaches, sun flower,cranberries, avocados, squash, string beans, chick peas, carrots, sweet potatoes, potatoes and some others.
Although some of these class 0 foods will cause TJ’s eczema to flare up a little bit at times because they are histamine-rich foods. During the winter these “safe-food flare ups” occurred much more often then they do now, therefore, we continue to smile on…
|Levels of IgE||Class #||Description||TJ’s Allergies Based on Class|
|0.56-1.40||II||Moderate||Coconut, Sesame, Pistachio, (Soy & Peas were both in this class; however, after food challenges, it was discovered he is not allergic to them.)|
|1.41-3.90||III||High||Hazelnut, Almond, Egg Yolk, Barley|
|3.91-19.00||IV||Very High||Rye, Oat, Wheat, Egg Whites, Peanuts,|
