    Area of Science:

    • Allergen immunotherapy
    • Clinical immunology
    • Respiratory medicine

    Background:

    • Allergy testing involves numerous pollen extracts.
    • Standardizing pollen extract testing is crucial for clinical practice.
    • Danish multi-center investigation on allergy diagnostics.

    Purpose of the Study:

    • To evaluate the clinical relevance of various pollen extracts in allergy testing.
    • To determine optimal strategies for routine pollen allergen testing.
    • To simplify diagnostic procedures for allergic respiratory diseases.

    Main Methods:

    • Multi-center study involving 5,052 patients.
    • Skin prick testing with 48 anamnestically relevant pollen extracts.
    • Computer-aided analysis of patient reactions to paired extracts.

    Main Results:

    • Identified dominant common allergens within tree, grass, and herb pollen groups.
    • Calculated the percentage of patients reacting to allergens present in multiple extracts.
    • Demonstrated significant overlap in allergenicity within defined pollen groups.

    Conclusions:

    • Routine allergy testing can be streamlined by using single representative extracts per pollen group (tree, grass, herb).
    • This approach enhances clinical relevance and simplifies diagnostic procedures.
    • Further validation of single-extract strategies is recommended for widespread adoption.
