Recent data has redefined the way that urologists look at PSA, and what is considered a normal PSA. Age-adjusted PSA values take into account that a 40-year-old should not have the same PSA as an 80-year-old. Accepted age-adjusted PSA rates are below 2.4 ng/ml for men under the age of 50 and 6.5 ng/ml for patients in their 70s. Other limits have been defined for varying age ranges, but there is not universal agreement about the accuracy of the age-adjusted levels.
The main difference between the PSA scores of prostatitis and enlarged prostate, compared to prostate cancer, is the ratio of free vs bound PSA within your test sample. 1  Prostate Cancer will have a higher bound PSA ratio. 2  An enlarged prostate and prostatitis will have a higher free PSA ratio. If your free PSA results are less than 25%, your risk for developing prostate cancer is between 10% to 20%. If your free PSA results are less than 10%, your risk for developing prostate cancer jumps to around 50%. PSA Test Velocity (PSA-V)
