With 10 or more tests and a comprehensive instruction manual in every box, catching a cheater has never been easier.***Accurate results in 4 simple steps***Step 1: Use a supplied dropper to remove a small amount of liquid from a bottle and wet the suspected stain with 2-3 drops. Allow the liquid to soak into the fabric and proceed to step two before the fabric has dried. Step 2: Using one of the supplied blotting papers, blot the entire wetted stain area, pushing down gently in different places, until the blotting paper is saturated. Set the blotting paper aside to dry. The blotting paper must be 100% dry prior to proceeding to step three. Step 3: Mix the solution by using a supplied dropper to remove 10 ml of the liquid from the opened liquid bottle and empty the liquid from the dropper into the bottle with power reagent. Shake for at least 30 seconds to mix completely. Step 4: Use the supplied dropper, remove a small amount of the mixed solution, and wet the blotting paper with 3 drops. Once you drop the mixed liquid onto the blotting paper start timing. The blotting paper will turn purple within 15 seconds if semen is present.

Review: Review - I'm writing this review to clear up misunderstanding about product as I see a couple. The gist of it is. It will turn purple instantly or within a maximum of 15 seconds. If it does not .Then it's a negative. It will however turn purple anyway if left on many other things for longer than 15 seconds. Summary 15 seconds or less anything more is false results. Hope this Helps
Review: Purple mean positive sperm - Fort idid it wrong. You have to let the paper dry before you put the other tuff. And it work

## Questions & Answers

**Q: My husband did the test, and it is wrong, ive never been with anyone. So what can i do now?**
A: Checkmate solution will turn a stain purple (almost) immediate but definitely within 15 seconds.  The solution is reacting with the stain (whatever it is) and the stain will turn many different colors after 15 seconds…sometimes red/yellow or purple.    That’s the beauty of the test…the color purple must/will appear within 15 seconds if the stain is semen…period!  I suggest redoing the test together and follow the instructions 100%.  

To summarize:    If the stain turned purple (light or dark) within 15 seconds after applying the mixed solution, then it is a positive result.  Whatever happens after 15 seconds doesn’t matter.  Remember, If you used the blotting paper it must be dry before applying the solution.

**Q: Does it work in black clothe, and could be used in it.**
A: Yes...the CheckMate kit includes white blotting paper used to blot the stain after you place a few drops of clear liquid (on the stain).  This removes some of the stain from the clothing to the (white) blotting paper.  Once the blotting paper has dried, you apply the solution that test for the presence of semen.  If semen is present, the blotting paper will turn purple within the first 15 seconds.

**Q: does it tell if there is more than one semin**
A: No, this kit will just determine if semen is present and will not differentiate between two different samples.

**Q: Does this work on dogs?**
A: No...Dog Semen contains alkaline phosphatase and Human Seman contains Acid Phosphatase.  Checkmate solution detects only Acid Phosphatase (AP).
