Shop online for environmental allergy tests to help identify airborne allergens affecting your immune system. These respiratory allergy panels measure the levels of IgE (immunoglobin E) antibodies your body produces when exposed to outdoor allergens (e.g. weeds, grass, pollen, etc.) and indoor allergens (e.g. pet dander, dust). Once you purchase a test, it's easy to schedule an appointment at one of 2000+ Quest Diagnostics locations nationwide. You'll get fast results online and have the option to discuss them with an independent physician at no extra cost.
