Air testing is usually the starting point. A small pump draws air through a collection cassette for a set period of time, capturing whatever spores happen to be floating around. The sample goes to the lab, and results show the types and concentrations of spores present indoors, which we then compare to outdoor baseline levels. It's a great general assessment and can flag problems even before any visible mold has appeared.
