label: Airborn particle hypersensitivity
label_lc: airborn particle hypersensitivity
description: "An abnormally increased sensitivity to airborn particles. This can be diagnosed on the basis of the medical history, taking into account seasonality or a relationship to the concentration of airborn particles in the environment of the affected individual. Aerosol challenge is a gold standard of establishment of the symptom. There exist particle hypersensitivity (diesel exhaust, metals, inorganic material) vs. allergen (including pollen dander, etc) hypersensitivity. The responses are usually different and testing for allergen hypersensitivity is done in concert with serum IgE and or skin testing to the suspected allergen."
