Measuring personal exposure to airborne allergens is important in understanding the association between asthma and allergen exposure. [1] Personal exposure to cat allergen (Fel d 1) is likely to involve a more complex pattern of exposure than indicated by either reservoir dust or long-term air Fel d 1 concentrations. [2,3]An additional limitation of current methods of air sampling is that the quantity of allergen recovered is low compared with the sensitivity of detection methods. We have developed a passive air sampler worn in each nostril which collects inhaled particles (mainly >5 MUm) and a method that detects the allergen eluted from each particle.
