Do you wonder if your partner is cheating? Maybe you’ve been suspicious about your partner’s behavior lately? You’re probably hurt, confused, and doubting everything. Is there a way to prove one way or the other if they are having an affair? How does lab infidelity testing really work? Rest assured–you can get the reliable answers you need to make potentially life changing decisions.
Semen Detection
While there are a variety of semen detection tests out there, lab testing is the only 100% reliable way to confirm a stain is semen. There are two lab test options available–semenogelin and microscopy. First is the semenogelin test. This test is specific to human semen. It will detect even very diluted samples of semen or semen mixed with other body fluids — in other words, the semen test will not cross react causing a false positive result. For this reason it’s the test crime and forensic labs use to confirm that semen is present on a sample. It is the follow up test done on all the other presumptive test samples. Microscopy, or the Christmas tree test, uses chemical reagents that color the head and tail portions of the sperm cells in different colors. This works only if there are sperm in the semen. If a man’s had a vasectomy, or naturally doesn’t produce sperm, it won’t be able to confirm that semen is present. Further testing is required.
There are also several varieties of home semen detection tests available. They each look for different proteins or enzymes found in semen. Because the substances they look for can be found in bodily fluids other than semen, they all are presumptive. This means any results need to be proven with a follow up lab test to confirm the results are accurate. No semen detection test, whether lab or home testing kit, can give you genetic information, or tell you if more than one man’s semen is present. For that, you need DNA testing.
Infidelity DNA Testing
DNA infidelity testing is the ultimate test for many who want to prove beyond a shadow of a doubt that their partner is being unfaithful. There’s no denying the presence of DNA that doesn’t belong to you. If you’ve found underwear, clothing, panty liners, or other items with signs of sexual activity it can be tested for DNA. It’s normally completed within eight to ten days, and can tell you if the semen or DNA in a stain is male or female; yours or someone else’s.
DNA detection testing, also called gender determination testing, will determine if DNA is present and if it’s male or female or a mixture of both. This test is used when you only need to know if there is male or female DNA present on a item.
DNA comparison testing will tell you if DNA is present, the gender, and if any matches a sample you provide. The comparison sample is usually in the form of a buccal or cheek swab, but many different items can be used. Things such as clothing, bedding, undergarments, and toothbrushes can be tested. No blood is required. This test is done when you want to confirm that any DNA present does or does not belong to a specific person.
How does infidelity testing work? Maybe you’ve been suspicious about your partner’s behavior lately and wonder if they are having an affair but don’t know how to find out. Have you found her underwear or sheets with signs of sexual activity? Or perhaps you’ve found stains in his car or on the furniture that can’t be explained? Is there a way to prove your husband or wife is having an affair? How does lab infidelity testing really work? There are different types of infidelity tests you can have done — semen detection, saliva detection, and DNA testing.
Semen Detection
Semen Detection — There are several varieties of semen detection tests, each looking for different proteins or enzymes found in semen. One type of test is an acid phosphatase or AP test. Because the enzyme is produced in the prostate, it can be an indicator of the presence of semen. However, it’s also found in vaginal secretions and other bodily fluids. Because of this, the test is considered presumptive and the most unreliable of all the testing options. This test is mainly used to rule out a stain for further testing. Confirmatory lab testing is required on any positive results.
The second kind of test is the PSA or prostate specific antigen test. PSA is another protein produced in the prostate. While some studies show PSA can exist in breast milk and urine, a positive PSA test is a strong indicator a stain contains semen. However, since there is still a chance of cross reaction, this test is not considered confirmatory or 100% reliable either. Again, follow up lab testing is required on any positive results.
Lab testing options are the only 100% reliable tests to confirm a stain is semen. The Christmas tree test uses chemical reagents that color the head and tail portions of the sperm cells in different colors. This works only if there are sperm in the semen. If a man’s had a vasectomy, or naturally doesn’t produce sperm, it won’t be able to confirm that semen is present. Further testing is required.
Finally, there is the semenogelin test. This test is very accurate and specific to human semen. It will detect even very diluted samples of semen or semen mixed with other body fluids — in other words, the semen test will not cross react causing a false positive results. For this reason it’s the test crime and forensic labs use to confirm that semen is present on a sample. It is the follow up test done on all the other presumptive test samples.
Infidelity DNA Testing
DNA infidelity testing is the ultimate test for many who want to prove beyond a shadow of a doubt that their partner is being unfaithful. DNA in humans is 99.9 percent identical. It’s the last 0.1 percent of the DNA profile that makes each of us unique. Comparing those sections of the DNA that are different is how we determine if two samples of DNA come from the same person. Unless you have an identical twin, the chances of another person’s DNA matching yours are a billion to one. There’s no denying the presence of DNA that doesn’t belong to you. If you’ve found underwear, clothing, panty liners, or other items with signs of semen or sexual activity it can be tested for DNA. It’s normally completed within eight to ten days and can tell you if the semen or DNA in a stain is yours or someone else’s.
DNA detection testing will determine if DNA is present and if it’s male or female or a mixture of people. This test is used when you only need to know if there is male or female DNA present on a item, for example. Or if you want to know if multiple males or females DNA is present.
DNA comparison testing will tell you if DNA is present, the gender, and if any matches a sample you provide. The comparison sample is usually in the form of a buccal or cheek swab, but many different items can be used. No blood is required. This test is done when you want to confirm that any DNA present does or does not belong to you.
