For Infidelity and Sexual Assault

Semen and Sperm Detection, Inc. provides 100% accurate and conclusive analysis for the detection of semen, sperm, and human saliva (and blood if applicable) to determine whether infidelity or rape has occurred. Our 4-phase testing process is the most accurate and reliable semen and saliva detection test available. A comprehensive written report is provided for each case, including photographic documentation. Tests are typically completed within one business day from receipt of the sample(s).

Semen Detections are primarily utilized in determining infidelity or rape.

Semen on Panties

Panties (examples) are tested more than all other items combined. Male underwear is the second most tested item. Common items include pants, feminine pads and tampons, bed linens, scrapings, washcloths, bathrobes, t-shirts, pants, pizza, blouses, lingerie, soft drinks, and juices, to name a few.

Do not terminate your relationship due to results of a home semen detection test kit. example1 example2 example3

If you use a home AP test there is a 35% chance that you will receive a false negative.

::DNA Extraction From Semen/Sperm

In the event your sample is positive for semen or sperm, you may elect to proceed with DNA analysis for further confirmation. The most common DNA extractions are the Y-PLEX, specific for male DNA, or the PowerPlex 18 Profile. Each of these extraction types are highly successful of producing a DNA profile . This evidence may then be used for comparison testing to determine if an individual is likely to be a contributor or is excluded as a contributor to the sample. Please see this link for additional types of follow up DNA tests that may be accomplished on a semen or sperm sample.

Expert Witness
Testimony - Criminal Case

I hired SSDI on behalf of a client who had been charged with indecency with a Child. SSDI went to the alleged scene of the crime to look for any physical evidence that would support the allegations against my client. From the initial sweep with an ultra-violet light to the comprehensive semen detection testing, SSDI did all the things the detectives on the case should have done for the prosecution. SSDI provided an excellent report regarding their procedures and their findings. Ultimately, the report served as the basis of SSDI's testimony at my client's jury trial. He was easily qualified before the Court as an expert and neither his credentials nor his report was seriously challenged. My client was acquitted after a brief jury deliberation. The jurors discussed the case with me after the verdict. The jurors agreed that they were very impressed with the work SSDI did on the case. They cited the work and testimony of SSDI as one of the primary reasons they returned a verdict of "Not Guilty." My client and I could not be happier with SSDI. I plan to use them again in cases like this one because they give me and my clients the advantage we need for trial.

The case settled without going to court. Final papers will be signed March 5th. She said to tell you thanks for what you did and the testing was a major factor in the settlement.

Negative Semen
Customer Testimonial

I never expected that I would catch my girlfriend cheating by having oral sex performed on her by her friend. I sent SSDI two pair of my girlfriend’s panties retrieved from a hotel room. The next day I received a detailed test report demonstrating that both pair of panties were negative for semen but positive for saliva. I needed closure to this so I ordered DNA profiling. A male profile was obtained and compared to my mouth swab and the two profiles were different. I confronted my girlfriend and she called me crazy and agreed to get a sample from the person I suspected (her friend) and also take a lie detector test. SSDI advised me to call her bluff and after attempting to get the suspects sample my girlfriend moved out. SSDI provided excellent assistance before, during, and after the testing. Scott from Ohio

AABB and ISO17025 Accredited Lab Testimonial

My laboratory has had the pleasure of working with the representatives of SSDI for over 8 years. I personally trained Steve Calvert at our lab in 2002 during the time period when we offered semen detections. Their representatives are well trained, experienced, knowledgeable, and professional. The significant majority of their positive semen detections processed for DNA yield a useful profile. I have full confidence in SSDI's semen detection testing and DNA preparation. Our lab often refers semen detection customers and dealers to SSDI.

Thanks so much for solving this for me. Not only was the speed very impressive but the thoroughness of your analysis was just what I needed to force my wife to tell me the truth after 2 years of deceit and lies. This was just beautiful!!!

Testing Performed With Each Order

Prostate Specific Antigen (PSA) . PSA is produced by the prostate gland (male specific) and secreted in seminal fluid. Unlike the acid phosphatase presumptive test, detection of PSA requires the presence of the semen protein without the need of the target to perform an enzymatic function. (additional PSA information).
Microscopic inspection - The substance is wet mounted and examined under a high power phase microscope for the presence of sperm.
Acid Phosphatase (AP) - This is a 97% presumptive test for the enzyme PH level found primarily in semen. This test will indicate the mass of the semen if the PSA test is positive. Why the AP test should never be used alone (such as a home AP kit).
Human Salivary Amylase (HSA) - This is the first confirmatory test for human saliva. The outcome of this test will determine if oral sex may have been performed even if the semen detection is negative. (additional HSA information)
Human blood detection included on all male underwear (excluded when male underwear is obviously worn by female).
Sperm Protein (SP10) test is run when semen is detected above a calculated level.
