Prostate-specific antigen; Prostate cancer screening test
No certain PSA level that is called normal or abnormal. No PSA level means you do or do not have prostate cancer. Remember that the PSA test cannot diagnose cancer. Only a biopsy can diagnose cancer. Always discuss PSA test results with your doctor
Your doctor will look at your PSA results and must consider your age, your race, medicines you are taking, and a number of other factors to decide whether your PSA is normal and whether you need more tests done.
Older men typically have slightly higher PSA levels than younger men. Normal ranges by age group commonly used include:
- Men below age 50: PSA less than 2.5
- Men 50 - 59 years: PSA level less than 3.5
- Men 60 - 69 years: PSA level less than 4.5
- Men older than 70 years: PSA level less than 6.5
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
