We often receive calls and emails requesting mold testing services. We also are asked if the home tests are any good. Well, it really depends on how accurate of a test/results want.  The Truth I can guarantee if you use a petri dish style spore capturing device and you send it to a lab, you will get results. The results will always show you have mold. Of course you have mold, mold spores are everywhere. You can put the petri dish anywhere and get results. They just won't be accurate results. On their website you will see fanfare and dropping corporate names as a way to bolster their product. In essence they might as well be selling tests for oxygen.  Simply put they rely on the ignorance of the general public to sell their product.  I can state with clarity, the results are not accurate nor indicative of the actual mold situation in your home. From an industry standard they would never be used to clear a project, post remediation. Which means their accuracy is poor...
