The Inhalant Allergy Panel (IgE) test is a quantitative serological test that measures serum levels of specific IgE antibodies against 35 common airborne allergens. These allergens typically include a variety of pollens (grasses, trees, weeds), house dust mites, pet dander (cats, dogs), and mold. It is used to confirm the diagnosis of allergic rhinitis, allergic conjunctivitis, and IgE-mediated allergic asthma.
