Includes the following: Like all our products, the semen detection test is a real evidence test, not a consumer toy. Forensic scientists use it in the field, and in laboratories. Step One: Use a semen detection test strip to check the stain for the presence of semen. Test multiple areas. A positive result rapidly turns the test strip bright purple. Step Two: Select the area that causes the brightest, fastest color change and confirm the presence of semen with a PSA test. A positive test result makes the kit show two red bars. The kit is discreetly shipped with no mention of the contents or the Crime Scene name on the box. Features: Test any item for semen Results in seconds Not a consumer toy.
