Office aeroallergen sampling

Aeroallergen sampling is a simple procedure that can be performed in any physician's office. The necessary equipment is a pollen and mold collecting device, a microscope with an eye-piece micrometer, pollen stain, and appropriate slides. The inexperienced observer can learn to count easily recognizable pollen and mold, such as ragweed and Alternaria in a matter of minutes. The counting can be simple (of one or two pollens) and can be complex, including counting of various molds under oil immersion.
