Validation of a novel sampling technology for airborne allergens in low-income urban homes

Allergens are distributed between the settled dust and airborne compartments. The airborne compartment represents inhalable allergen that penetrates deeply in the respiratory tract and may trigger asthma symptoms.1 Larger airborne particles may also trigger allergic rhinitis. Because methods of air sampling have been technically demanding and limited by assay sensitivity, dust collection has been a standard surrogate. Raulf et al reviewed methods for measurement of airborne allergens.1 More recent studies have described potentially improved methods.
