PSA (prostate-specific antigen) is one of the most requested blood values for men. An elevated PSA can have various causes, from an enlarged prostate to prostate cancer. But what is normal and when should you act?
Normal values by age
40-49: below 2.5 ug/L. 50-59: below 3.5. 60-69: below 4.5. 70-79: below 6.5. PSA rises naturally with age as the prostate grows.
Causes of elevated PSA
Benign prostate enlargement (most common), prostatitis, prostate cancer, recent ejaculation, prolonged cycling and urinary tract infection.
Important note
PSA is prostate-specific, not cancer-specific. An elevated PSA does not automatically mean prostate cancer. Discuss the pros and cons of testing with your doctor.
Frequently asked questions
When should I test PSA?
Discuss with your doctor from age 50 (or 40-45 with family history). For urinary symptoms, testing is recommended regardless of age.
