The report puts three sets of numbers side by side: the samples from before treatment, the clearance samples and the outdoor air. Outdoor air always carries some spores, so a clearance result is read against the outdoor sample, and nobody should expect a count of zero.
Each room is reported on its own. A room that still reads high shows up by name, which tells you where to look for moisture next.
The report also lists the genus for each sample, so you can see whether the mold that stood out in the baseline has dropped back toward what the outdoor air carries.
