Free and total PSA test
In some cases you may be offered a free and total PSA test to help show how aggressive the prostate cancer is. This measures the ratio between two different types of PSA found in the blood (free and total). The idea is that men with an elevated total PSA number will have a higher percentage of Free PSA if there is something other than cancer occurring in the Prostate. There are a variety of new blood tests for prostate cancer….ask your doctor!
