Testing for mold in your home is not really a complicated process, but if you should know that if you do not follow the instructions that come on the package to the letter, the test will be almost completely useless both to you and to the mold laboratory that you send the test kit samples to. Most test kits are fairly straight forward, but this is a rundown of what you are going to have to do, even if you do not use just the test kits.
Sometimes knowing where you need to test for mold contamination is pretty easily simply because of the fact that the mold is either completely visible on the walls, ceiling, or other belongings, but also due to the fact that many kinds of mold have a significant musty odor to them. You can take a sample of the mold that you can see on the walls by taking a knife (a clean one) and scraping some of it off into the test kit. Be careful here and do not inhale the mold spores. Wear rubber gloves and a respirator while doing this, if you can. Whether you are wearing gloves or not, though, you should wash your hands afterward before going to test another site and especially before you eat anything.
If you want to, you can also take a piece of scotch tape and lift some of the mold off the wall. Some people may prefer this over the knife method, but it is a matter of personal preference. The knife method is more likely to stir up the spores than the tape method.
Set a test kit out in every room of your home after you have run the air conditioner or fans in every room for about ten to fifteen minutes to get the spores stirred up. Tape at least one kit to the grill of an air conditioning vent so you will know if there is any mold growing inside the duct itself. If the air conditioner continues to blow mold spores out into the house after it has been run for about 15 minutes, you know you have a problem in your ventilation system.
After you collect the test kits from around your house, you need to label them all with your name, address, where each test kit was used in the home, and any other pertinent information. This should also include how long you left the test kit setting out in your home, whether it was 30 minutes or a day.

General Rules For Mold Testing Kits
If you are unfortunate enough to have to test your home for mold, you are probably thinking that this is going to be a pretty inconvenient thing to have to do. Well, it might not be fun to think that you have disease-causing mold living in your house, but doing the actual test to determine if it exists is not really that hard to conduct at all. Whatever kind of test kit you end up using, the directions on the package must be followed to the exact letter or you will probably render the test useless. There are a few quite general rules that you should follow to get the most out of your testing kits.
If you can see the mold growing in your wall, ceilings, carpet, or on anything else in the home, you do not really have to do any guesswork as to whether you need to test the home or not. If you see anything like this, do not only test that room; test your entire home. Every room needs to be tested and this includes the ventilation system, because it extends to every room in the house and if mold is growing in the vents, it will spread to the rest of the house.
Run the air conditioner or fans in every room in your home before you put out the test kits so that if there are any mold spores in the room, they will be stirred up into the air and will settle down in the kit. Do not set them up anywhere high; a coffee table or somewhere around the mid to low level of the room should be fine. If you set them up too high, you may not get a good sample.
If there happens to be mold growing visibly on anything, you can use a piece of scotch tape to lift the mold up off the surface and place it into the test kit. There is a method that you can use involving scraping some of the mold into the kit with a knife, but since this can stir up mold spores even more, unless you are wearing a respirator, you are probably better off using the tape method.
To test the ventilation system, the best thing that you can do is tape a test against the grill of one of the ventilation ducts so that the air coming out of it is hitting the testing kit at a 90 degree angle. This will allow you to get the maximum amount of exposure.
