A follow-up test that measures free prostate-specific antigen (free PSA) may be used to see if a prostate biopsy should be done to check for cancer. Free PSA is the percent of prostate-specific antigen that is not attached to proteins in the blood. The lower a man's free PSA percentage, the more likely he is to have prostate cancer. A man with a total PSA between 4 and 10 ng/mL may have a test to find out his free PSA, to see if cancer is likely to be present.
The PSA test is not perfect, and there are a few new blood tests being developed to replace the PSA test such as the 4KScore and the PHI test, both of which are prostate cancer. Depending on the clinical setting in which PSA is used, the typical prostate biopsy is positive for cancer in men with elevated PSA levels. The mean measured percentage of free PSA (free PSA/total PSA X 100) in the 90:10 PSA preparations was 15.
