Immunoglobulin (IgE)  Immunoglobulin (IgE)  (Inmunoglobulina E
(IgE))  Many people have allergy-induced asthma, which means
that their asthma symptoms are triggered by allergic reactions.
These people have high levels of an allergy-causing antibody (a
type of immune protein in the body) called immunoglobulin E
(IgE). When they inhale something that they are allergic to, it
attaches to the IgE, which then starts a chain of events leading
to symptoms of allergies and asthma.
