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.
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.
