The term ‘black mold’ is a bit general. In most cases, when someone refers to black mold they are referring to a known species of mold which can cause some reactions, stachybotrys.
While this mold can be toxic to people, it is not the only species from which people can have reactions. In fact, aspergillus, another species regularly found in homes, tends to affect a larger percentage of people with respiratory complications.
The standard for determining whether or not you have a mold issue in your home is whether or not mold counts are higher indoors than outdoors.
Often, folks will find mold growing, visibly apparent, in a corner of their home. While this mold could be an issue and needs to be cleaned up, the presence of mold growth may not equate to an overall air quality issue.
There are two ways that an owner could test for mold to determine if mold is PRESENT. There is no way to determine, in a home test, if mold is DANGEROUS. Only an expert can visibly inspect, determine where to test, and interpret those results in a meaningful way.
A homeowner can buy a swab test at a Home Depot. It will tell you what species are present. A homeowner can also buy an air exposure test, usually in the form of a Petri dish, that will tell if mold is in the air. Neither of these methods will inform you of the level of mold, the danger of associated species, or next steps.
