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.
