I purchased a mold test for my home recently. I didn’t know what to expect with them, but it was kind of expensive. Luckily, it comes with a laboratory test to find out what sort of mold I have. When I received it, I found that it came with petri dishes and some packets of solution.
It was easy to mix these in the petri dish, considering all it takes is hot water. A small swirl and a swish will allow it to mix, but make sure you read the instructions that come with it. Some of them come with small tubes that you have to scrape mold samples into.
DC 911 helped me a lot when I thought I had mold in my home. The petri dishes settled with their solution and I was able to test the area that I believed had mold. I had to test the air quality since there were no visible signs of mold on my walls. I let the air settle on it for a few hours and then covered it for a couple of days.
It was about 72 hours before I noticed that there were things growing on the surface. It was definitely mold-like, so I sealed the petri dish and sent it off to the lab. I got the results back in a few days and then scheduled a mold remediation service, since it tested positive for mold.
