If we don’t find the mold on the surface, we’ll use a few different testing methods to make sure there is or isn’t any mold. One method of sampling we can use, is Surface Sampling. During a Surface Sample, we can take a lift ape or swab sample of the area. Once we get an appropriate sample, we’ll send it off to the lab. Another method we can use is called Air Sampling. With an Air Sample, our team collects a sample through a sampling pump into a cassette. Then the sample is sent off to the lab for testing.
