More Test Examples

It is an absolute fact that there is no better semen detection test kit available then our PSA kit.  If there is PSA kit equal to ours it’s because they copied our design and instructions such as the SemenSpy kit.  We developed the first PSA home kit ever sold so that consumers would absolutely know if the stain contained semen.  The PSA cartridge used in our kit is much more sensitive than any other PSA or P30 cartridge tested including the OneStep ABA Card® p30 based on available test data.

Evergreen’s so called patented product is an AP test kit.

It is an absolute fact that all AP tests are presumptive.  Ask any degreed scientist in the industry.  We have 4 PhD’s in the industry available for consultation at a nominal charge of $50. Contact us or call us at 888-875-7574 to setup your consultation.

False positive results will happen because Acid phosphatase is an enzyme present in the cells throughout the body. It is present in especially high concentrations in the prostate and semen in men.  Many other substances contain high AP.

This link from The Journal of Criminal Law, Criminology, and Police Science, Vol. 47, No. 6 (Mar. – Apr., 1957), demonstrates that AP tests are frequently false positive. http://www.jstor.org/pss/1140071

AP tests are also shown to provide false negatives by our validation study.

False negative results will happen because AP cannot be detected in samples containing less then 78 ng and demonstrated by our validation study and other white papers.

This link from the New England Journal of Medicine displays that acid phosphatase tests are false negative when the semen detections are positive. This applies to all AP tests, not just home kits. http://content.nejm.org/cgi/content/abstract/312/6/338

This link from the American Journal of Forensic Medicine and Pathology demonstrates that other substances cause a positive AP test when the substance is not semen.http://www.semenonpanties.com/Reference/APevaluation.pdf

Here is published data on how rapid their product drops off during comparison testing.

See the last paragraph of the Virginia State Crime Lab Manual where the results of a positive AP test alone are identified as inconclusive http://www.semenonpanties.com/VirginiaForensicScience.pdf
