IGHE and Allergy: This paper describes work undertaken as a proof of principle study, to investigate the feasibility of using commercially available air sampling pumps, deployable by study participants, and allergen measurement techniques to quantify airborne protein concentrations (in this case of common environmental aeroallergens) in homes, at concentrations relevant to potential use in risk assessment and furthering our understanding of human-dose response relationships associated with the development of IgE mediated allergies.
