There are a number of inherent limitations to mold testing. Testing is only warranted when there is a clear objective that can only be met through obtaining sampling data. In a residential setting, there are more reliable and cost effective methods for identifying environments needing intervention. A thorough visual inspection looking for mold growth or signs of water damage and wetness and locating sources of mold odors by smell is recommended. Once mold growth has been located, appropriate actions are needed to correct the source of the moisture and remove mold contamination.
Mold can make people sick.
Mold can only affect health if people are exposed to the tiny particles or chemical by-products of the mold. Exposure mainly occurs via inhalation of airborne mold products or to a lesser degree through bare skin contact with mold contaminated materials. Because all of these factors can vary considerably over time and from person to person, the extent and severity of health problems due to any specific indoor mold situation is unpredictable. Nearly every type of indoor setting can host mold growth which might affect occupants' health. Although mold is only one of many possible causes of symptoms related to poor indoor air quality, it should be considered a potential hazard to occupants whenever evidence suggests excess moisture is occuring.
