How long has CheckMate been on the market?

Will this test stain the suspected garment?   

The CheckMate semen detection test kit is designed specifically for ease of use by the everyday consumer and it will leave no trace of the test procedure on the suspected article. The only thing you will be putting on the garment is 2 to 3 drops of the distilled water that comes in  each test kit and you can be certain that CheckMate does not stain the tested item.  

How does a man know he won't detect himself?

As the man performing the test you should abstain from having sexual intercourse with the woman being tested for a period of 7 days to insure there is no possibility of detecting yourself. That way if you do get a positive test result infidelity has been proven.

How accurate is this product? I mean, the results can be life changing.

The CheckMate product works exactly as specified and all you've got to do is test a known semen stain to prove or verify your test results. CheckMate also comes with information from our recommended DNA lab where you can also have the tests verified using DNA if you like. Plus, the product has been on the market for over ten years too and if you were to call every store listed on our website you'd find out that they've never had even one single complaint about the product or the accuracy of the results, and that's because it really works.

Of course not, and in fact because CheckMate is intended for use by untrained consumers in the home it was designed from the outset to be a highly reliable product that anyone can easily use. Additionally, while very low levels of the enzymes detected by the CheckMate test kit are present in every  cell in the human body, only in the male prostate gland are these same enzymes found in an ultra elevated state that can be as much as 1000 times higher than anywhere else in the human body, male or female, and that's why only semen can cause a positive test result.

Watch out for unethical negative advertisers: Due to the fact this industry has become polluted by unethical negative advertisers who have no regard for the truth the CheckMate company wants you to know that our product not only works, we sell thousands of test kits a month to distributors, to retailers, to websites, as well as to people just like you from all around the world too, and if our product didn't work like we say it does there's just no way so many people would have been using and selling it for over ten years.

Can women use CheckMate too? 

Women love CheckMate and they find the most creative ways to use it too. In fact we have women customers who purchase CheckMate once a month like groceries because it gives them a way to find out what's really going on without even having to leave the house.

How many items can I test?

CheckMate is advertised to perform 5 to 6 tests on the box but the product can actually test far more than 5 to 10 items and you also get a second test kit free with every order too.

How long does it take to get the results?

CheckMate gives instant results from the comfort and privacy of your own home without having to send your spouses undergarments half way across the country for testing. With CheckMate you do the test and only you know the results.

Will CheckMate work on panty liners?

Yes, CheckMate will work on panty liners too.

How old can the stain suspected semen stain be? 

Dried semen is a very resilient substance that can live on as testable evidence for many year under the right conditions. Simply store the suspected article in a paper bag at normal room temperature and perform the test when your kits arrive.

Does machine washing remove any semen stains?

Like any other stain, machine washing does of course remove semen stains from clothing. Men will not detect themselves on the suspect garment from any previous sexual activity prior to laundering.

Can't I just do the same thing with a U.V. light?

Are you kidding? Things do not happen the way you see on television and the idea that a semen stain can be detected with a black light is nothing but an untrue urban legend. A alternate light source is used to find hidden stains, not tell you what the stain is, that's impossible, and anyone who tells you any differently is either lying or they have no idea what they are doing or talking about.

That's why you can see the same hand held U.V. lights being sold by online scam artists to detect semen stains also being  sold on other websites to detect cat urine stains. It's a fact, even with the fancy orange goggles you see people using on TV you could spend the rest of your life attempting to differentiate between a dried semen stain and a normal vaginal secretion and the only thing you'd come up with is absolutely 100% nothing. The light is only used to tell you where a stain might be on a large area such as a blanket but when you're talking about using the CheckMate test kit to detect semen stains in underwear the suspect stain is typically visible to the naked eye and no ultra violet light is needed to locate the stain for testing.

What about condoms?

If there is no semen present on the garment then of course CheckMate will not work and we certainly make no claims that it will. CheckMate is for people that have already discovered a suspicious stain who need a quick and easy way to find out what it is.
