Frequently Asked Questions About Semen Detections
There is semen on my wife's panties and it's not mine, how do I test it?
FAQ on Semen, Sperm, and Vaginal Discharge
FAQ on PSA vs. AP Infidelity
Having tested hundreds of non clothing items for
semen such as shower drains, wood chips, carpet, condoms, pizza,
hair, spit in baggies and cups, finger wiping on tissues, floors, combs
and brushes, food wrappers, feminine pads and tampons, band aids, fistulas
from medical procedures, bed linens, bed posts, wash cloths and
towels, tooth brushes, just to name a few, these items account for
a fraction of the number of tests performed on underwear. All
items above account for less than 2% of the items we test.
(98%) of our serology tests were performed
on panties, feminine pads and male
SSDI is the most
experienced private serology test lab for infidelity
testing. We remain on the forefront of technology
by developing new products and processes. Having developed
the first non-presumptive semen detection kit in 2002 to our
current validation of a specific sperm protein
marker to specify the presence of sperm in a sample (even when
badly degraded), you are guaranteed the most accurate and
conclusive testing available.
The sample can be any age. There is
data supporting 30 year old samples
testing positive for semen.
Place any sample in a brown paper bag or
Mark the sample envelope with the date
the item was worn or the date the sample was obtained if
not worn (when possible).
Store cloth samples at room temperature until testing
Positive test results will include this
date (when provided) and the results on panties and
feminine pads will specify when the intercourse most
likely took place.
crime labs have the capability and experience to perform
this test (besides SSDI). We integrated the
infidelity saliva test as part of our semen detection in
We have many cases where the suspect is
caught by positive saliva results when the semen detection
test was negative. See our testing
report section for details on the outcome of many tests
including negative semen detections where human saliva is
detected and proven by a DNA analysis to be from a male
(not the husband).
We are the only private company including saliva detections
as part of every semen detection test.
We recommend that you do not let
the outcome of any home semen detection test result
in a life changing situation (such as a divorce). If
you confront your spouse before you have 100% conclusive
results you will jeopardize your relationship.

four different tests run by
professionals for only $245.00 that includes the most reliable and
sensitive PSA test, an acid phosphatase test which indicates
how much of the stain is semen, a microscopic inspection
for sperm, and a human saliva detection test.

A black light can be helpful in locating
biological stains for testing.
No expert can look at a random set of
stains and tell you which one is semen.
We use an expensive selectable multi-band
UV forensic lamp to fluoresce
each article before the extraction is accomplished so that
we obtain sampling from every stain. Then we follow
that with another unit that provides an exact 450 nm wavelength,
combined with special orange glasses, which makes invisible
semen stains visible.
The $10 black lights sold on the internet
are better than nothing...but not much. If you are
getting one free with your home kit, expect the cost to
the supplier to be between $2.50 and $5.00.

This test is not presumptive like the Acid Phosphatase (AP)
test commonly found on the internet. A positive reaction
with our PSA test means the prostate specific antigen found
only in semen is present.
