Some of the tests are actually quite reliable, but they can be difficult to read correctly without the proper experience. Additionally, these tests don't give a full picture of the issue, as they don't tell you what kind of mold is present, where it's located and if it's toxic or not.

Air sampling is the most accurate method for determining exposure. While a tape lift may accurately determine if mold growth is present on a particular surface, it will not tell you whether that mold growth has actually affected the indoor air quality. Only an air sample can accomplish this.

borescope: This is a camera that can visualize suspected mold growth and other problems inside plumbing pipes and structural elements through an opening in the component. rotameter: This device measures the air flow rate, which can be helpful to determine if the home has conducive conditions for mold growth.
