I had a friend call me last night, knowing that I had been through the treatment of PCa over the last two years. He assumed I knew a lot on the subject because we have discussed my "study" a number of times. He went to his doctor and had a "free PSA" test and the result came out 10. I had not heard about free PSA and could be no help. Obviously I googled it immediately, after hanging up the phone, and got an answer that was "grey", especially with his numbers. They indicate if you have a high free PSA (opposite of what I was accustomed to) you were more likely involved with benign hyperplasia (above 15). If you are below 15 you should have further diagnosis, and if you are below 7 you probably have prostate cancer (on the last two numbers I may a bit hazy, and this is what is critical). Sounds like it is a test to determine whether biopsy is advisable. He is 75 years old, very healthy otherwise, and seems to have come away from this believing that his number (10) indicates that further investigation is not needed. Also, nothing palpable with DRE. After the little bit of reading that I did, I am not so sure that I concur.
My question is: Have you had, dealt with, or studied "free PSA" testing, and what is your knowledge? Any help would be appreciated.
