Mold testing procedures were not developed to determine whether a home is “safe” or “healthy” or “clean." Although this article is titled "Mold Testing" it actually tells you why testing for mold is usually not needed. For more information, see Popular Topics/Homeowner Resources.

If you see mold or you smell mold you have mold. You do not need to test for mold if you see it or smell it. Knowing the type of mold does not change the way you respond. All mold should be treated the same way. It should be removed without exposing people to lots of mold spores or fragments and the underlying moisture problem causing the mold should be fixed. Knowing the species (type) of mold does not affect what must be done to correct the moisture problem or to safely clean up the mold.
