The Rapid Stain Identification RSID™ Series is a unique group of tests developed by Independent Forensics, designed to identify a specific bodily fluid at a crime scene. However, unlike most other tests on the market, each test is specific to human saliva, semen or blood. After locating the suspected stain, a technician simply swabs the area and applies collected material to the appropriate test for a positive or negative result of human fluids. If the test produces a positive result, enough biological material is preserved for successful DNA STR analysis. Since each test is specific to human bodily fluids, they will not cross-react with other animal fluids. Each kit is sensitive enough to detect as little as 1 microliter of saliva, semen or blood, and are so specific, they are considered confirmatory tests.

Quickly and reliably detect human blood from evidence encountered in the field using the RSID™ Human Blood Field Kit. Unlike other tests on the market, the RSID™ Human Blood Field Kit is specific to human blood. Each test includes all materials needed to perform the stain analysis, as well as document and transport the results. The RSID™ Human Blood Field Kit results correlate with the ability to obtain DNA profile data with no cross reaction observed with human saliva, semen or urine and no cross reaction observed with animal blood. Each kit detects as little as 1μl of human blood.
