Hygiena offers the environmental monitoring test, a self-contained, ready-to-use swab test which contains a liquid medium which changes color when species are present in the sample. A color change from purple to bright yellow indicates presence, with positive results in as early as 24 hours from sample collection. The all-in-one test device eliminates the need for sample preparation materials, saving material and labor costs. Other environmental species test kits require several complicated steps including measurement and mixing of media, sample enrichment, and transfer of enriched sample to the test device
