In people with allergies, reactions are triggered
because the immune system encounters something it sees as a threat – such as dog dander. This leads to the production of antibodies
that are specific to that allergen, called Immunoglobulin E (or IgE). The next time the body encounters the allergen,
IgE triggers the immune cells to release chemicals causing symptoms, most commonly in the nose,
lungs or on the skin. Many people think they’re allergic to a certain
thing, but in fact, it could be something else. Along with your symptoms and history of allergic
reactions, one single blood test to identify IgE antibodies can help your healthcare provider
identify what you may be allergic to, which could help you better manage your condition.
