In this article you read mold analysis results. To get an accurate answer to the meaning of your mold lab results, the results should never be interpreted on their own. Instead, your personal visual assessment and a detailed/critical inspection, together with the building history, should be able to provide sufficient explanation. You will often find some labs that offer an interpretation of the mold results, but you have to provide them with the building assessment data. You also have to provide them with information on what exactly you were trying to achieve with the results.

There are several steps in the determination of whether or not mold is present. These results are then paired up with other observations to produce for you the meaning. Following are the meanings of the results.

  1. Determining whether building materials have mold

The most appropriate way of determining whether building materials have been invaded by mold is through the use of tape-lift samples. Sometimes it becomes impossible to use the scotch tape on wet surfaces to collect samples. In such a case you can use dry swabs. If the samples show the presence of spores and mycelium, then that would indicate the growth of mold within the indoor area.


  1. Determining whether or not indoor air has the typical and normal amounts and types of airborne mold spores.

Air samples are the most ideal in this form of testing. The term typical and normal amounts and types of airborne spores can be referred to as the normal types and amounts of molds found in buildings that have no record of ventilation issues or water leakage problems. Therefore, a building that contains a typical and normal amount of mold spores can be having various spore types at much lower levels than what is present outside. Spores of Penicillium or Aspergillum may be present even in buildings that have no history of poor ventilation or water damage. What’s more is that they could be exceeding the percentages and levels of these spores outdoors. In this case, moisture-indicating molds such as Chaetomium should be absent.

If it occurs that airborne spore concentration is higher indoors than it is outdoors, it means that the origin of the spores is not outdoor air alone but also an indoor source such as mold growth is present. The growth of this mold could be linked to a leaking roof, a cold spot behind the drywall, or a plumbing mishap that has been ongoing for some time.

After removal of mold, you often want to determine whether it was successful. A visual inspection, for starters, is recommended. However, advanced testing is recommended, and that is where air testing comes in handy. This is done to ensure that the occupants of the building are not exposed to high levels of airborne fungal spores and to ensure that fungal spores were not spread in every corner of the building during the testing process.
