Question: how often should you have a psa blood test?
Answer: Men ages 50 to 59 should have their PSA level checked. If the PSA level is 3 ng / mL or higher, men should talk with their doctor about having a biopsy of the prostate. If the PSA level is between 1 and 3 ng / mL, men should see their doctor for another PSA test every two to four years.
