Semen Detection Kit

Semen Detection Kit

The frequency of sexual crime is increasing alarmingly and the field expert is compelled to gather and preserve highly fragile, unstable physical evidence. The following products are designed to aid in evidence identification and collection.

This is a complete field and lab kit that enables the investigator to perform contact testing and verification of suspected seminal stains. This test is considered to be the most conclusive test for the presence of semen. The content of this enzyme is from 20 to 400 times greater in human semen than in any other fluid. This fact makes it unlikely that another material would test positive and give false results.

Acid Phosphatase Test

A 2-5 drop aliquot of deionized water was placed on a suspect area of a garment, and an AP test strip was pressed against it. A color change to bright purple within 15 s was a POSITIVE test. Alternatively, a cotton-tipped swab was placed against the wetted area of the garment, and then the garment was pressed gently around the swab in order to saturate the swab with solution. This was done in several places on the garment. Then, the swab was pressed against an AP test strip. This procedure yielded an easily visualized, high-contrast spot. It also avoided leaving any stain on the garment.

Prostate Specific Antigen Test

A 15-mL aliquot of water was placed in a coffee cup. The suspect area (i.e. crotch) of a pair of cotton underwear was extracted in the cup by repeatedly allowing water to soak in, then pressing it out. Finally, the garment was wrung out into the cup. A PSA test strip then was placed into the cup. It was necessary to tilt the cup on edge to immerse the strip. Care was taken not to immerse the strip above the marker line. After 10 minutes, the strip was removed and laid on a clean, dry surface. The strip was read after an additional 10 minutes. Resolution continued to improve for 30 minutes after the strip was removed from the coffee cup, but tended to decrease after that. A POSITIVE test was indicated by two lines as shown in Fig. 10. A strongly positive test was clearly visible within two minutes, while a weakly positive test took 20 minutes (after immersion) to become evident.
Absorptive pads were tested by placing 25 mL of water into the coffee cup (for a full pad) or 10 mL for a mini-pad, and repeatedly extracting the pad manually. Then, the pad was wrung out into the cup and discarded. The PSA test was carried out as usual.
