SPECIFIC IgE BLOOD TESTING
A powerful tool with one blood sample
Immunoglobulin E (IgE) is an antibody naturally produced by the immune system.
If a person is exposed to an allergen—a usually harmless substance like pollen, pet dander or a certain food—and their type of IgE mistakenly identifies an allergen as an “invader,” their immune system could:
- Overreact and produce IgE antibodies that travel to cells in the body, such as cells in the skin, throat, nose or lungs
- Release chemicals in the body that cause an allergic reaction, producing mild or severe allergy symptoms 2
An allergen-specific IgE test measures the levels of certain IgE antibodies—with just one sample of blood—to help identify which allergens may be causing unwanted symptoms.
