Summary

This study is testing a blood test called Proclarix to see if it can better identify men with aggressive prostate cancer before they have a biopsy. About 500 men aged 40-75 with certain PSA levels will give a blood sample before their scheduled biopsy. The test results will be compared to the biopsy findings to see how accurate it is at ruling out serious cancer.
