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.
Generally speaking, though, PSA levels for men who are: Age 60 or older: should be at or below 4.0 mg/mL; Age 59 or younger: should be at or below 2.5 mg/mL; The average PSA for men in the younger group is <1.0 mg/mL. Why are my PSA levels elevated? Your PSA levels could be elevated for many reasons.
There is no specific normal or abnormal level of PSA in the blood. In the past, PSA levels of 4.0 ng/mL and lower were considered normal. However, some individuals with PSA levels below 4.0 ng/mL have prostate cancer and many with higher PSA levels between 4 and 10 ng/mL do not have prostate cancer (1).
In general: 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.
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)
A PSA level between 4 and 10 means you have over a 25% chance of having prostate cancer. If you have a PSA level greater than 10, you have over a 50% chance of having prostate cancer. It’s very important to talk to a healthcare provider about a prostate biopsy if your PSA is in these ranges.
Review the typical prostate-specific antigen (PSA) ranges by age and what your next steps might be if yours is higher.
A PSA in the range of 4-10 nanograms per milliliter is linked to a 25% chance of prostate cancer. Most people with a PSA below 4 nanograms per milliliter don't have prostate cancer, but...
