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.
Prostate-specific antigen levels correlated with age (r = .43 [rÂ² = 18.5]; P less than .0001); a higher correlation of PSA with PSA density was found (r = .55; P less than .0001); and PSA density was weakly correlated with age (r = .25; P = less than .001).urrently, a single demarcation between normal and elevated PSA values, 4.0 ng/mL, is used as an indication for biopsy among men of all ages. The use of age-specific reference ranges might address several shortcomings of the PSA test.
