Bedroom Exposure to Airborne Allergens in the Chicago Area Using a Patient-Operated Sampling Device

Background: In current practice, allergens in vacuum collected dust are used as surrogates for inhalable allergens. We developed an airsampling device that can be used by patients themselves for direct measurement of airborne allergen concentrations in their own homes.Objective: To demonstrate the use of this device to establish allergen concentration reference ranges in a target population. To evaluate relationships of patient-reported information to measured allergen concentrations.Methods: Patients from 5 allergist's practices in the Chicagoland region were provided with instructions, questionnaire, informed consent forms and samplers to run for 5 days in their bedrooms.
