If you have found a suspect stain on your husbands underwear, clothing or bed
sheets, the item can be sent to the laboratory for DNA Testing to confirm if the stain
is only from your husband or if it from your husband and another woman or man.
Ultraviolet (UV) light is a popular tool in many forensic investigations for the
presumptive identification of body fluids on a variety of items. Materials such as
semen, saliva, perspiration and vaginal secretions are naturally fluorescent under UV
light which offers a discriminating method for locating these stains which might
otherwise be invisible to the naked eye.
Biological stains resulting from sexual activity often contain a mixture of both male
and female DNA. The female DNA usually originates from epithelial cells from the
vaginal wall, the mouth or skin, while the male DNA comes from sperm cells. After
the stain is extracted, a DNA profile is then created.
If the DNA shows that the stain is from 2 people (your husband and another person),
we can use DNA testing to show whether or not the second person is you or an
unknown person. We do this by having you submit a cheek swab of yourself. We will
then compare your DNA profile to that of the DNA from the item you sent in, to tell
you whether or not the second person is you or someone else.
If you suspect your husband of infidelity but have been unable to detect a physical
stain, it is possible that the undetectable stain is a result of oral sex.
Ultraviolet (UV) light can be used to locate the stain. Once the precise location of the
stain is determined, a Saliva Test can be conducted to determine the origin of the
stain.
Lingering doubt about your husband's
possible infidelity can wreak havoc on
your emotional state of being. Put those
doubts to rest with a DNA, Semen
Screen or SalivaTest, the only fool proof
method for determining infidelity.

Articles, such as underwear, clothing and bed sheets containing suspicious stains
can be rapidly and reliably screened for the presence of semen utilizing a
combination of three techniques: ultraviolet illumination, prostate specific antigen
(PSA) and microscopy. Even if a man is vasectomized, his semen can still be
detected.
Ultraviolet Examination
Ultraviolet (UV) light is a popular tool in many forensic investigations for the
presumptive identification of body fluids on a variety of items. Materials such as
semen, saliva, perspiration and vaginal secretions are naturally fluorescent under UV
light which offers a discriminating method for locating these stains which might
otherwise be invisible to the naked eye. Once the precise location of the stain is
determined, presumptive testing can be conducted utilizing the p30 and microscopy
techniques.
Prostate Specific Antigen (PSA)
Prostate specific antigen, also known as PSA, is secreted into seminal fluid. The
PSA test is an extremely sensitive, presumptive technique that allows for the low
level detection of seminal fluid in stains. The technique is extremely powerful
because it can confirm the presence of semen even in samples from sterile or
vasectomized men.
Microscopy
Sperm heads can be accurately identified based on their morphological
characteristics via microscopy.
