Environmental Allergy Testing: Pollen, Dust, and Pet Allergens
Environmental allergy testing identifies IgE antibodies to inhaled allergens such as tree, grass, and weed pollens, dust mites, mold spores, and pet dander. It can be done with a blood test or a skin-prick test, and each approach has advantages depending on your skin condition and medications. A positive result indicates sensitization, and your symptoms help determine whether it is a true allergy. Testing can guide avoidance strategies and treatment decisions, so results are best reviewed with an allergist.
