I agree. These tests are inaccurate. I'll just quote you something so as not to sound self-promoting. This comes from the Indoor Air Quality Association: "Indoor air quality problems can have a major impact on occupant health and comfort. When indoor air quality issues arise, it is important to make sure that only highly-qualified individuals are called upon to investigate, mitigate and confirm that a problem has been properly resolved...IAQ problems in non-industrial buildings such as homes, schools and offices are often caused by complex, inter-related issues. Diagnosing and fixing the sources of poor IAQ may require the professional expertise of one or more consultants or contractors. It is important that individuals be highly qualified to fully investigate, identify and/or mitigate the total problem according to recognized industry standards and guidelines. Verification of contracting or remediation work, if requested, should be conducted by an equally qualified third-party consultant." The IAQA does not sell professionals for profit. They are an independent organization that aids in government regulation, scientific study, education, and some professional oversight. There are so many ways to be exposed to indoor pollutants, to focus on mold singularly could overlook other pollutant sources (both in air and on surface of building materials and content materials). Having a professional with no ties to remediation (so there is no conflict of interest) can help you understand the condition of the environment in which you're occupying. It can also give you some information to share with your doctor for treatment. I am a Council-certified Indoor Environmental Consultant. If I can be of any further help I'll do my best.
