PSA levels can be detected in the blood, urine, or semen. Blood PSA testing is used as a screening test for prostate cancer. Prostate-specific antigen (PSA) levels by age remain the same across most populations. A PSA level above 4.0 ng/mL in any age group must be investigated.
What’s a “normal” PSA level? Doctors tend to categorize PSA levels in terms of “elevated” or “non-elevated,” rather than “normal” or “abnormal.” That’s because the range of what’s normal varies by age.
There's no one PSA level that's considered normal. In general, PSA levels are higher in older people than in younger people, even in those who don't have prostate cancer or other...
Normal PSA Levels: 0 - 4 ng/mL; Slightly Elevated PSA: 4 - 10 ng/mL; Moderately Elevated PSA: 10 - 20 ng/mL; Highly Elevated PSA: 20+ ng/mL; PSA Levels by Age Chart (Free to Total Ratio)
What is a normal PSA test result? What is done if a screening test shows an elevated PSA level? What are some of the limitations and potential harms of the PSA test for prostate cancer screening?
For men in their 40s and 50s: A PSA score greater than 2.5 ng/ml is considered abnormal. The median PSA for this age range is 0.6 to 0.7 ng/ml. For men in their 60s: A PSA score greater than 4.0 ng/ml is considered abnormal. The normal range is between 1.0 and 1.5 ng/ml.
The PSA test can detect high levels of PSA that may indicate the presence of prostate cancer. However, many other conditions, such as an enlarged or inflamed prostate, also can increase PSA levels. Therefore, determining what a high PSA score means can be complicated.
