Abstract
Respiratory allergies represent one of the most prevalent immune-mediated disorders worldwide, such as allergic rhinitis and asthma. The advent of in vitro diagnostic methods, particularly those based on molecular allergology, has revolutionized the diagnostic approach to inhalant allergies by enabling precise identification of sensitizing allergens at the molecular level. This review presents an analysis of the current status of in vitro diagnostics in respiratory allergy to plants and molds, with emphasis on molecular diagnostics for key allergens from trees (e.g., birch/Betula verrucosa), grasses (Poaceae family), weeds (e.g.mugwort/Artemisia vulgaris, ragweed/Ambrosia artemisiifolia), and molds (e.g. Alternaria, Aspergillus). We discuss major allergenic proteins, diagnostic tools, implications for precision medicine, and integration with precision immunotherapy.

| Trees, grasses, and weeds share common pan-allergens (i.e., profilins and polcalins), which can lead to false positive reactions in skin prick test or whole allergen extracts. |
