The total PSA range of 4 0 to 10 0 ng mL has been described as a diagnostic "gray zone," in which the free PSA:total PSA ratio helps to determine the relative risk of prostate cancer (see table) Therefore, some urologists recommend using the free PSA:total ratio to help select which men should undergo biopsy
