What is IgE?
	IgE is the antibody associated with allergy.  When a foreign invader or substance is recognized by the immune system, antibodies are produced against specific substances, such as pollen. There are specialized classes of antibodies with different functions in the body. The IgE class is associated with allergic reactions. Pollen, for example, is inhaled and an immune process takes place in allergic individuals causing wheezing, sneezing, coughing, etc., depending on the location of the allergic reaction.
