what is a normal psa level

The normal PSA level can vary depending on age and other factors. In the past, a PSA level of 4.0 ng/mL and lower was considered normal. However, more recent guidelines suggest that the normal range is between 1.0 and 1.5 ng/mL. Its important to note that there is no specific normal or abnormal level of PSA in the blood, and the reading varies from man to man, increasing as men age. For men in their 40s and 50s, a PSA score greater than 2.5 ng/mL is considered abnormal, while for men in their 60s, a PSA score greater than 4.0 ng/mL is considered abnormal. Additionally, a PSA score may also be considered abnormal if it rises a certain amount in a single year, for example, if it rises more than 0.35 ng/mL in a single year. Its important to discuss PSA levels with a doctor to understand what the results mean for an individuals specific circumstances.
