What Is A PSA Test?
The Institute recommends for men to keep track of their PSA level, as any one reading is not as significant as the “trend over time.” We believe there isn’t a “normal” PSA level, as the number may change due to a number of factors. One of the biggest influencing factors is age because the prostate grows as men mature, which, in turn, creates a higher PSA level.
For an accurate PSA reading, men should avoid:
- Sexual activity 48 hours prior to taking a test.
- Excessive bike riding or lengthy car rides.
- Finally, never take a PSA test for two weeks after a digital rectal exam, or six to eight weeks after a TRUS or a biopsy. Any procedures dealing with the prostate—whether non-invasive or minimally invasive—will increase PSA levels.
Patients should have a TRUS done if the PSA level is more than 2.5 ng/ml or the digital rectal examination is abnormal, regardless of the PSA level. For high risk men, a TRUS examination is recommended if their PSA level is over 2.0 ng/ml.
