Why is the new BIOSAFE PSA4 so much better?
A. BIOSAFE has introduced a new system designed to change the way PSA testing is done. BIOSAFE PSA4 is accurate, convenient, easy-to-use, and private. It allows the self-collection of a blood sample for laboratory analysis. BIOSAFE PSA4 provides the accuracy and reliability of a laboratory test but eliminates the need to have blood drawn from the arm.
