What is CheckMate? 

The CheckMate 5 Minute Infidelity Test Kit™ is the quick and easy home use test kit that instantly detects and uncovers the traces of dried semen that can be found in a woman's underwear after sexual intercourse. Designed to instantly prove a sex act has occurred outside of the relationship, this revolutionary product can also immediately put your mind at ease by telling you nothing is going on. 

How does it work? 

If a woman has unprotected sexual intercourse with a man, there will always be a semen stain present in her underwear afterwards. Similar to the tests performed by CSI in rape and homicide investigations, CheckMate uses a patented process to instantly  detect these traces of dried semen in the undergarment, giving you the instant information you need to deal with an impossible situation.

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.

How old can the stain be? 

The age of the suspected  dried semen stain is not even a factor to consider when performing this test. All CheckMate test kits are tested and guaranteed to accurately detect dried semen stains up to two years old. However, in most cases you will be testing articles where you think the stain may have been recently deposited, meaning any garment obtained from a relationship setting is perfectly testable. Remember, we're testing dried stains. Once the stain is dried on the material that's exactly where it's going to stay. Simply store the suspected article in a paper bag at normal room temperature until your test kits arrive. 

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 leaves no trace of the test procedure on the suspected article. PLUS... The CheckMate semen detection products also work on any type or color of material. Test undergarments, furniture, linens, auto upholstery etc. without fear of damage or stain.

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.

Will lotions, creams, medicines, etc will effect the test?

Lotions, creams, medicines, etc will not effect the test. Plus, CheckMate is such a well built product that if you want to see for yourself, there is more than enough material to test everything in the house including things like lotions, creams, medicines, etc. That way you can see for yourself that all of these things do not effect the test.

What if the guy she is seeing has had a vasectomy? 

Yes, CheckMate detects semen from men who have had this procedure performed. Semen and sperm are two different things. A vasectomy does stop the delivery of sperm but ejaculation and semen production remains normal. 

I'm a woman - Does it show female semen on his underwear?

Only men produce semen and there is no reason for a guy to come home with semen stains in his underwear. If you think he's cheating and you wait until the right time, it's easy to set a guy up and catch him with CheckMate. After all, if a man has semen stains in his underwear, he had an ejaculation while he was away from home, and you just got your answer no matter how it got there.

Contrary to popular belief men do not "leak semen", men do not have wet dreams, men do not blow their nose in their underwear, and men do not have semen stains in their underwear simply because they stood next to a pretty girl at the supermarket. For any semen to be present at all, even the pre ejaculatory fluid that is secreted before ejaculation, a man must first have an erection, and it must be for an extended period of time, which is exactly what you're looking for.

What if he masturbated at work?

What if he did? Guy's are weird, and it happens all the time. There was even a radio talk show a while back dealing with that exact subject and when the host asked the caller how he did that at work, the caller responded by saying, "Well tom, I just put my chair down real low!" Plus, most women want to know if that is going on too, and believe it or not so do a growing number of businesses.

The real fact is, CheckMate is an amazing information gathering device and in the vast majority of real world cases there is simply no legitimate reason for a man to have 3 different semen stains in his underwear in 3 different places. Furthermore, what many people don't understand about CheckMate is the fact when it comes to women using the product it is typically used by women who have already discovered a suspicious stain and who basically already know what the stain is just by looking at it. In fact most women who buy CheckMate are simply getting it to confirm their suspicions after he said something like he blew his nose in his own underwear, which actually happens.

I'm a guy - if it is semen is there any way to know it's not from me?

If you use the CheckMate 5 Minute Infidelity Test Kit according to the instructions you will automatically know the that any semen that was discovered was not from you. But, you can also prove the semen in question was not from you by performing a DNA type test to prove it's not from you. CheckMate comes with all the information and contact information about DNA  testing too.

Do I need a U.V or "black light" to use CheckMate?

No, a black light is not needed to perform the CheckMate test. The ultra violet light is for when you're testing a large area like a blanket or carpet and you don't know where to begin testing. A light cannot identify a stain as semen, but once you isolate a stained area with a light, then you can test it with CheckMate.

Have you seen those commercials on tv advertising black lights to locate cat urine stains? Now, do you think a black light can identify a semen stain? Of course not, thousands of different substances will fluoresce when subjected to ultra violet light, that's why some people say C.S.I. actually stands for "Crime Show Inaccuracy," because things simply do not happen like you see on television.

A black light can however be a handy thing to carry in your suitcase because it just about guarantees a hotel room upgrade every time when you scan the bedspread and discover one or two hundred different stains left by other people and their pets. Most people don't notice the fact that the maids are only changing the sheets and pillow cases, but it's true, and even though in most cases you will certainly find countless stains on any unwashed hotel bedspread, for the most part the stains will all look the same under a U.V. light and there is simply no way to tell a semen stain from coffee with cream and sugar. There's hoards of people who want you to think otherwise too, but don't believe a word of it because it's simply not true.

What is the shelf life?

Like every other product in the store CheckMate test kit has an advertised unopened shelf life of one year. All components and packaging are also shrink wrapped and safety sealed to further insure product integrity and long life. In fact, the makers of CheckMate have successfully tested semen stains that were over 3 years old with CheckMate test kits that were over 2 years old.
