There are 2 different types of mold tests, a swab sample and an air quality test. If there is a specific area of the house that has visible microbial growth, this can be tested with a swab sample to determine what type of growth it is.
Two air quality samples are taken inside the house to determine what type of spores are in the air. An additional sample is required to determine what type of spores are in the outdoor air. This sample is also called a control. These to samples are compared to determine if there are elevated spore counts on the interior sample.
Both the swab and air quality samples are sent to the lab to be tested to determine what was found. From the day the sample is submitted to when the results are received is 3 business days or less.
