The program is an outgrowth of the 1986 National Childhood Vaccine Injury Act (NCVIA), which requires health care providers to report: Any event listed by the vaccine manufacturer as a contraindication to subsequent doses of the vaccine.
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.
The PSA level also is determined in part by the size and weight of the prostate. The test measures the amount of PSA in the blood in nanograms per milliliter (ng/mL). A PSA of 4 ng/mL or lower is normal; 4â10 ng/mL is slightly elevated; 10â20 is moderately elevated; and 20â35 is highly elevated. Most men with slightly elevated PSA levels do not have prostate cancer, and many men with prostate cancer have normal PSA levels. A highly elevated level may indicate the presence of cancer.
