Allergens in commercial house dust

L E Mansfield, H S Nelson

    Annals of Allergy
    |April 1, 1982
    PubMed
    Summary

    Commercial house dust extracts contain major allergens like mite, cat, and dog dander. Potency varied significantly between different manufacturers' extracts, with human dander and cotton linters being minor contributors.

    Area of Science:

    • Allergy and Immunology
    • Environmental Health

    Background:

    • House dust is a common source of indoor allergens.
    • Understanding the composition of commercial house dust extracts is crucial for allergy research and diagnosis.

    Purpose of the Study:

    • To analyze the allergen content of commercially available house dust extracts.
    • To compare the allergen profiles and potencies of different house dust extracts.

    Main Methods:

    • Analysis of allergen content in commercial house dust extracts.
    • Identification of major allergenic components, including mites, cat dander, and dog dander.

    Main Results:

    • Mite, cat dander, and dog dander were identified as the primary allergens in most house dust extracts.
    • Significant variations in allergen potency were observed among different commercial extracts.
    • Endo dust exhibited a different allergen profile compared to standard house dust extracts.
    • Human dander and cotton linters were found to be minor contributors to overall allergenicity.

    Conclusions:

    • Commercial house dust extracts vary considerably in their allergen content and potency.
    • Mite, cat, and dog allergens are the most significant components in these extracts.
    • Further standardization of house dust extracts may be necessary for consistent diagnostic and research applications.
