Measures immunoglobulin E (IgE) antibodies to 25 common respiratory allergens to help determine allergy presence.
This test measures the level of IgE antibodies your immune system produces in response to specific tree pollen, weed, grass, and common indoor allergens. It helps you and your healthcare provider determine if you have an allergy. The panel includes allergens like various weeds, grasses, tree pollens, and common indoor allergens such as pet dander, mold, and dust mites. A positive result indicates an elevated IgE level, suggesting a potential allergic response, but further evaluation by a healthcare provider is necessary for diagnosis and treatment. This test is crucial for identifying allergy triggers and managing symptoms.
