title: Antigens and allergic asthma.
abstract: There are few reliable epidemiologic data on the overall frequency and importance of allergy. We describe a practical method for quantifying the concentration of both amorphous and morphologically defined antigens in the air. A high volume air sampler is used to collect airborne particles and has a facility to separate samples into different particle sizes. Samples are tested for allergenic activity by radioallergosorbent test inhibition assay. Preliminary findings from studies of community wide, amorphous and common household allergens are reported.
