What is the “normal” PSA level?
A PSA value of >4 ug/L has often been defined in the literature as abnormal and is frequently used as a cut-off point by some jurisdictions including Ontario and the United States. However, a man’s PSA level increases steadily as he ages, and some – not all – urologists advocate the use of age-related “normal” PSA cut-points, rather than using >4 ug/L for all. It is recommended that men should talk with their doctor in regards to PSA levels.
