PSA Testing for Prostate Cancer

The PSA blood test is currently the best tool we have for catching prostate cancer early, when it's most treatable. Get tested. It may save your life.

What is a 'normal' PSA level?

There is no specific 'normal' or 'abnormal' PSA level. Also, various factors can cause a PSA level to fluctuate. The information below provides guidance on what is considered a normal PSA range, and what may be considered a dangerous PSA level.

  • If you are between ages 40 and 75, and
    • Black/African American, and/or
    • Have a family history of cancer and/or a known genetic mutation that increases the risk for prostate cancer
      • Discuss the risk and benefits of prostate cancer screening with your doctor
      • Have a baseline PSA and strongly consider a baseline digital rectal exam (DRE)
      • If PSA less than 1 ng/mL and DRE normal (if done), repeat testing every 2 - 4 years
      • If PSA 1 - 3 ng/mL and DRE normal (if done), repeat testing every 1 - 2 years
  • If you are between ages 45 and 75, and
    • At average-risk
      • Discuss the risk and benefits of prostate cancer screening with your doctor
      • Have a baseline PSA and strongly consider a baseline DRE
      • If PSA less than 1 ng/mL and DRE normal (if done), repeat testing every 2 - 4 years
      • If PSA 1 - 3 ng/mL and DRE normal (if done), repeat testing every 1 - 2 years
  • If you are over age 75
    • Talk with your doctor about if prostate cancer screening should continue
    • If PSA less than 4 ng/mL and DRE normal (if done), repeat testing in select patients every 1 - 4 years
    • If PSA greater than 4 ng/mL or a very suspicious DRE, talk with your doctor about further testing and follow-up
