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.
In general, it is accepted that a PSA level above 4.0 ng/mL is considered to be on the high end. The National Comprehensive Cancer Network outlines the current PSA results: Less than 1 ng/mL is considered benign. Men with increased risk should repeat testing at 2 to 4-year intervals.
Prostate gland Enlarge image The PSA test is a blood test used primarily to screen for prostate cancer. The test measures the amount of prostate-specific antigen (PSA) in your blood. PSA is a protein produced by both cancerous and noncancerous tissue in the prostate, a small gland that sits below the bladder in males. If your PSA results are in the borderline range (4 to 10), the % free PSA can be useful in helping distinguish between prostate cancer or benign prostatic hyperplasia (BPH). The pattern is the OGSLMZ.
