Aside from the harsher comments, I value all the responses given very much. I am not very familiar with mold at all. This was my first "mold test" it was the Pro-Lab do it yourself kit. After you gain results you can send them in, yet others claim it takes up to a month, and poor results. I was unaware that much mold is in any standard air. The test commented "if nothing grows no test is needed" so that had me thinking if anything grew it was an issue. I am not as concerned, thank you for the help.
