With Kidde's MOLD DETECTION KIT, detection of mold couldn't be simpler " just open the package, place the Mold Kit sampler in the area to be tested, and enclose the sampler in the enclosed self-addressed envelope for lab analysis. The cost of the kit does not include the laboratory analysis fee. The fee for each location sample test strip and/or bulk sample is $10. A detailed report will be sent to you within 72 hours of receipt of the test and the laboratory fee. This kit provides sampling capacity for up to 6 mold samples taken via mold strips and up to three "bulk" (2" x 2" x .5") samples such as a piece of carpeting, wallpaper, wood or similar material.
