Why should I have food allergy/antibody testing?
Scientists estimate that approximately 12 million Americans suffer
from food allergies.* A food allergy or sensitivity is an immune system
response to a food that the body mistakenly believes is harmful. Once
the immune system decides that a particular food is harmful, it creates
specific antibodies to it.
Two major types of food reactions involve antibody production in your body:
Immediate Reactions to Foods (IgE)
Classic allergic reactions occur within 3 hours after eating. They are
usually caused by high IgE antibody blood levels that produce an
immediate allergic response. This allergic reaction may appear as a rash
after eating foods like strawberries or crabmeat. The potentially fatal
but very rare “anaphylactic” reaction after eating foods like peanuts or
shellfish is another example of an “IgE” reaction.
Delayed Reactions to Foods (IgG4)
These reactions are much more difficult to notice since they can occur
hours or days after consumption of an offending food. Yet, this “delayed”
type of reaction is far more common than the immediate IgE type. In
some cases, you may eat a food for several days before developing a
reaction to it, so you may not realize the link between the food and
your symptoms. These delayed reactions to food are often referred to as
“hidden” food sensitivities. They are caused by increased IgG antibody
blood levels in reaction to specific foods. Often, the offending foods are
hard to avoid and frequently eaten, such as milk, corn, and wheat.

triggering many different symptoms and
contributing to a variety of disorders
including:
