Free PSA? No…you pay for it!
The below is helpful but not a stand alone type statistic or characteristic of your PSA.
- I have a friend whose free PSA was very high indicating a low probability of prostate cancer and ….all of his twelve cores showed cancer, however all the cores were Gleason’s 6.
- The free PSA (being very low) was what prompted me to “get off the fence” and do a biopsy..so in that regard it sometimes is that extra shove in the reluctant patient.
- I have had patients with a low free PSA and no cancer.
In general the chart below indicates that you have a higher chance of having prostate cancer on a biopsy if your free PSA is low, and vice versa if it is high, but again this is not fool-proof and should only be “one of the arrows in your prostate decision-making quiver.”
