Assays of mite allergens (Der p I, Der f I and Der II) in the air of houses became feasible with the use of a low-noise air sampler and a sensitive radioimmunoassay described previously. The levels of the airborne allergens Der I (Der p I + Der f I) and Der II in the living room of 10 houses during usual domestic life were very low, 29.5 and 6.3 pg/m3, respectively, with a Der I: Der II ratio of 4.7:1. At the time of bedmaking, they greatly increased, about 1,000-fold, to 30,900 and 12,600 pg/m3, respectively, with a Der I: Der II ratio of 2.5:1. The amounts of Der I and Der II in the floor dust of the living room were 2,040 and 2,690 ng/g of fine dust, respectively, with a Der I: Der II ratio of 0.8:1. Der I seemed more prone to become airborne than Der II.
借助低噪音空气采样器和先前描述的灵敏放射免疫测定法，对房屋空气中螨过敏原（Der p I、Der f I和Der II）的检测变得可行。在正常家庭生活期间，10所房屋客厅中空气传播过敏原Der I（Der p I + Der f I）和Der II的水平非常低，分别为29.5和6.3 pg/m³，Der I与Der II的比例为4.7:1。铺床时，它们大幅增加，约增加1000倍，分别达到30900和12600 pg/m³，Der I与Der II的比例为2.5:1。客厅地板灰尘中Der I和Der II的含量分别为2040和2690 ng/g细尘，Der I与Der II的比例为0.8:1。Der I似乎比Der II更容易悬浮在空气中。
