The guidelines provide a rough guide to normal PSA levels (ng/ml) by age group. Age less than 60 years ~ less than 3.0 ng/ml; Age 60–69 years ~ less than 4.0 ng/ml; Age 70-79 years ~ less than 5.0 ng/ml; Even if your PSA level is within the normal range, if your GP has any concerns you may be asked to have your PSA level checked again.

The serum total PSA was also plotted against the age of the participants and there was a significant correlation of higher serum PSA with increasing age of the population under study (Spearman's Rho = 0.36 and p < 0.01
