The Respiratory Allergy Panel Region 10 measures IgE antibodies to common allergens, including molds (Alternaria, Aspergillus, Cladosporium, Penicillium), grasses (Bermuda, timothy), trees (birch, oak, cedar, cottonwood, elm, maple, pecan/hickory, mulberry, white ash), weeds (ragweed, pigweed, sorrel, nettle, marsh elder), and indoor allergens (cat and dog dander, dust mites, cockroach, mouse proteins). This panel helps identify triggers of respiratory allergies.
