To find out if you have mold in your home, you might need to hire a commercial mold tester. However, there is an alternative that you can perform yourself, which only requires items you most likely have in your home already; a roll of tape and a plastic ziploc bag.
If you have an area in your home that you suspect is growing mold, you can test out this process to find out what the truth is.
First, take a piece of tape and press it up against the suspected mold carefully. After doing this, stick the tape to the inside of the plastic bag and send it into a lab for testing. It really is as simple as that. From this tape sample, a lab will be able to let you know what type of mold there is and how severe the infestation is. On a positive note, this is accomplished without damaging the area where you sample or releasing spores into the air.
