Free PSA

PSA that is unattached to any major protein in the blood. Free PSA is associated with benign prostate growth. The percentage of free PSA is derived by dividing the free-PSA level by the total-PSA x 100. Studies have shown that men with free PSA%>25% were at low risk for prostate cancer, while men with PSA%<10% were at high risk for having prostate cancer.
