1 Men in the range of 60 to 69 years have normal PSA levels that are less than 4.5 ng/mL. 2  Men over the age of 70 years have normal PSA levels that are less than 6.5 ng/mL. 3  It is also important to note that the normal ranges of PSA results may vary from one laboratory to another.
About one in three men with a PSA level between 4 and 10 ng/ml will have prostate cancer, although this proportion varies with the population tested. Studies have shown that there is still a small risk of prostate cancer even if blood PSA levels are normal for age (a false negative result).
