Abstract
We measured major mite and cockroarch allergens in indoor environment with immunoassay using allergen-specific antibody. It is impossible to count airborne particles microscopically in some airborne allergens derived from mites, cockroarches, cats, and laboratory animals, which can only be detected with immunoassay. Other advantages of the assay are that it is much easier to be standardized and allergen contents can be expressed in absolute units. The major issues discussed in this review are : (1) levels of major allergens in houses, (2) evaluation of countermeasures for reducing exposure to airborne allergens, and (3) particle sizes of airborne allergens.
