The air we breathe indoors has millions of microscopic particles floating around that will eventually fall to a surface. Some of these particles can cause adverse health issues. The Allergen Screen Check identifies and provides concentration levels for allergens such as mold, pollen, dust mites (intact), skin cells, insect parts, fibers, etc. that can be found on surface locations in the home or workplace. This do-it-yourself test kit is easy to use: collect a sample using the included one-surface sampling device, return it to the AIHA accredited lab, and results are emailed to you in 3-5 days at no additional cost.
