Infidelity Testing

Sperm/Semen Detection

Bodily secretions, during and after sexual intercourse, are deposited on various personal items. These items may include, undergarments, clothes, condoms, feminine hygiene products, bed sheets, towels, toilet/bathroom tissues, carpeting and mattress. These deposited bodily fluids remain a valuable source as dried stains for many years. Semen deposits contain prostatic acid phospatase (PAP) enzyme, Prostate Specific Antigen (PSA) and millions of sperms. These markers are routinely used to determine presence of semen in forensic samples.

Dried stains can be tested to determine the presence of PAP enzyme. However, this test is highly Presumptive because many other body fluids, specially vaginal secretions, also contain PAP enzymes. The presence of PAP in vaginal secretions and other body fluids, makes this technique unreliable for the confirmatory detection of sperm/semen and may lead to False Positive Results. Also PAP enzyme in older stain samples becomes inactive and can NOT be detected with this test and may provide False Negative Results.

Sperm detection using DNA technology is the most powerful technique. Even a small amount of male specific DNA can be successfully detected using DNA based techniques. When there is question of infidelity DNA testing designed specifically to detect male specific Y chromosome can provide vital answers. The DNA profile of the sperm that is detected by Y chromosome analysis then can be matched or compared to other samples or DNA from other sources. Sperm detection services may provide unquestionable evidence for infidelity. Sperm detection services are for those who would like to determine the presence of sperm (Y chromosome) within sheets, articles of clothing, fabrics, stained material or just about anything that is suspected of being soiled.
