Test confirmed by professional testing service
When our little rent house tested positive for mold, according to a company specializing in that service, I installed a dehumidifier and an ozone mold killer, both bought from Amazon. A month or two later, I bought this and ran the test. The test showed no mold remained, so I called the professionals out, and they confirmed it. The test is at least accurate in giving an "all clear".
