Testing Services - Allergens

An allergen is any substance that can cause an allergy. In technical terms, an allergen is an antigen capable of stimulating a type-I hypersensitivity reaction in atopic individuals through Immunoglobulin E responses. Most humans mount significant Immunoglobulin E responses only as a defense against parasitic infections. However, some individuals may respond to many common environmental antigens. This predisposition is called atopy. In atopic individuals, non-parasitic antigens stimulate inappropriate IgE production, leading to type I hypersensitivity. Sensitivities vary widely from one person (or other animal) to another. A very broad range of substances can be allergens to sensitive individuals.

Allergens can be found in a variety of sources, such as dust mite excretion, pollen, and pet dander. Food allergies are not as common as food sensitivity, but foods such as nuts, seafood, and shellfish are the cause of serious allergies in many people.
