Do you have a clothing item or stain you need to test for the presence of semen? This semen test kit contains 5 test strips, allowing you to do 5 complete tests. The Semen Detection Test Strip gives instant results. A positive result turns the test strip bright purple. The kit is discreetly shipped with no mention of the contents or the Crime Scene name on the box. The semen detection test is a real evidence test, not a consumer toy. It is used in the field and in laboratories by forensic scientists. Unlike consumer tests sold online, there are no liquid chemicals to mix, allowing for failsafe results. You can optionally test several items with a single strip. To do so, cut the strip into pieces. Your order includes five semen test strips, cotton swabs and nitrile gloves.
