Indoor mold testing is often mistaken for mold investigation. Mold testing is part of mold investigation at the lab level. It can also be referred to as mold analysis.
Is mold testing necessary?
In the post, Indoor Mold Sampling, it was mentioned that some experts consider mold sampling as unnecessary especially where there is visible mold growth. Going by this argument, it can then be said that mold testing/analysis of visible mold is not necessary. However, if one is conducting a Mold Investigation as opposed to Mold Inspection, then mold testing could be necessary depending on the objectives and goals of the investigation. Mold investigation is a more complex process than just determining whether there is visible mold growth or not.
Purpose for Mold Testing or Mold Analysis
The main purpose for mold testing as part of mold investigation is to determine things that the naked eye is not capable of discerning. For example, for visible mold, we cannot tell what type of mold it is without testing in the laboratory. It would also be difficult to determine whether the air was contaminated with mold particles or spores released from areas of visible mold growth thus exposing the occupants.
Samples Collected for Mold Testing
A mold investigation should have a goal or purpose. What are you trying to find out or to achieve during the mold investigation? It is important to know what samples are appropriate for the investigation that you are conducting. Having a clear goal makes interpretation of mold test results easy.
