To insure your satisfaction it is advisable but not mandatory to generate a known dried semen sample and do a side by side test. This may also help you interpret the results of your test.

MEN

When using CheckMate timing is very important. If you suspect your female partner of having sex with someone other than yourself, you must make certain you have had NO sexual intercourse with her for at least 7days. Semen can be detected even after showering for up to 72 hours or more so be sure your have had no relations with her for specified time period. Failure to follow these guidelines could possibly result in a false positive test result. Everyone's situation is different but use common sense when using this product. CheckMate test only for the presence of semen not who it came from.

WOMEN

Timing is the most important factor for the proper use of this product. For women using this test on a man you must consider things like masturbation and personal habits and hygiene.  CheckMate is very easy to use. Just wait until the "right" time to do the test. Everyone's situation is different but a good example  would be.... If he takes a shower, puts on clean clothes and goes out with the boys every Friday night then Saturday morning would be a good time to do the test.

PARENTS

Of course undergarments are the best place to test but only you will know when is the "right" time. Everyone's situation is different. Just follow the easy Instructions.

IMPORTANT

The two supplied kits are designed to perform several tests each.  DO NOT MIX BOTH TEST KITS TOGETHER AT THE SAME TIME. AFTER COMBINING THE LIQUID AND THE POWER IT REMAINS USABLE FOR A 24hr. PERIOD AND SHOULD BE DISCARDED AFTER THIS TIME.

Step One

If you can actually see the suspected stain use the supplied dropper and remove a small amount of liquid from bottle #1 and wet the suspected stain. This only takes 1-2 drops. If you can't see a stain but suspect one may be present, simply wet the suspected area. Allow the liquid to soak into the fabric. If you are doing a side-by-side test with a known sample you should also place 1-2 drops on this stain now also. After the liquid has soaked into the fabric being tested proceed to step two immediately before the fabric has any chance to dry.

Step Two

Using one of the supplied blotting papers simply blot the entire wetted suspected test area with the paper by pushing down gently in different places until the paper is thought wetted. If semen is present this transfers it from the material being testes to the blotting paper so let the paper soak up the liquid. Now set the paper aside to dry. If you are doing a side by side test with a known sample do the same as above on the known semen sample but with a different piece of paper and set it aside to dry also. YOU MUST MAKE SURE TO DO THIS AFTER.....Not before you do the test. If you were doing the blotting part of the test on the known semen sample first you could possibly the suspect test paper. So if you decide to do the side-by-side test always do the suspect test first.

Step Three

Using the supplied dropper remove 10ml (2tsp) of the liquid from bottle #1 and mix it with bottle #2. Shake for at least 30 seconds to mix completely.

Step Four

For the last step you must time yourself carefully. Don't guess. Use a timer or a watch with a second hand.

After the blotting paper has dried shake bottle #2 again and using the dropper extract a small amount of the mixed fluid form the bottle. Place a small amount of the liquid onto the suspect blotting paper. (1-3 drops) If you are doing a side-by-side test place a small amount of the fluid onto the known sample at the same time.

As soon as you place the liquid onto the paper start looking at your watch. If semen is present you will see purple color START to appear on the paper almost immediately. If semen is present you will see this start to happen within 15 seconds or less. If the purple color does not appear within 5 seconds it is not a positive test and no traces of semen are present. Any red, yellow or even slightly purple coloring that appears after an extended time is definitely not a positive test result.

No traces of the test will be left behind on the material being tested. If you are not concerned with staining the material and it is a light color like white, you can place the fluid mixture directly onto the suspected test area. The same procedure should be followed as to the timing part of the test. If semen is present even in the smallest trace amounts you will see the purple color appear within 15 seconds.
