Type I hypersensitivity reactions (IgE mediated) are a rapid allergic reaction to specific antigens found in, e.g. house dust, pollen and animal danders.

The symptoms and signs of the reaction are apparent within 30 min of the exposure. Atopic individuals are susceptible to type I hypersensitivity reactions.
