What are normal results for the PSA test?
The "normal" PSA serum concentration remains a debate, however, for most laboratory readings, it should be less than 4.0 ng/mL. The prostate gland generally increases in size and produces more PSA with increasing age, so it is normal to have lower levels in young men and higher levels in older men. As such, the concept of age-adjusted PSA normals have been described and recommended. The PSA level also depends on ethnicity and family history of prostate cancer. Other than the single reading, the changes in PSA numbers on an annual basis (also referred to as PSA-velocity) also play a role in decision making about the PSA marker. The normal increase of less than 0.75 ng/mL is used to help determine whether levels may be suggestive of disease and to counsel men on management. As such, a man 50 to 59 years of age with an increase in PSA levels from 0.5 ng/mL to 2.5 ng/mL may have prostate cancer despite the normal value at that time.
