PSA blood test results are reported as nanograms per milliliter, or ng/ml. Normal levels usually range from 0 ng/ml to 4 ng/ml, although what is considered normal may vary by age and race. Mild to moderate increases in PSA between 4 and 10 are considered borderline, while levels over 10 are considered high. The re-screening interval can be 1 to 4 years for patients with PSA levels of 1 to 3 ng/mL between the ages of 45 to 70 years, while the re-screening interval can be prolonged for patients aged 45 to 70 years with a PSA < 1 ng/mL or those with a PSA below the age-specific median. 58, 63, 69 Studies have shown that patients in the age range of Fig. 1 - Age-related rise in prostate specific antigen. The central value is the median. The upper and lower values represent the 95% 'normal' range or reference interval. While these results refer to the Abbott Architect method and an Australian population, the values will be similar for any internationally calibrated (WHO standard) PSA assay In general: 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 For men in their 60s: A PSA score greater than 4.0 ng/ml is considered abnormal. The normal range is between 1.0 and 1. An abnormal rise: A PSA score may also be Prostate-specific antigen (PSA) is the only widely available test for detecting prostate cancer. recommendations on when to refer patients based on their age, symptoms and signs, PSA and DRE results. The GP Tool can be accessed via Medtech32 and Medtech Evolution e.g. in a younger man with a PSA at the higher end of the normal range. 22. The free PSA level was stable up to 50 years of age. It then significantly increased. The upper limit of the normal value was measured as 0.42 in the range of 20-30 years and as 0.53 in the range of 60-70 years with an annual average increase rate of roughly 0.5%. Overall there was a linear regression between age and the free PSA rate (r = 0.12 The Elecsys ® free PSA is a quantitative in vitro diagnostic test for determination of free PSA (free prostate specific antigen) in human serum and plasma. 13. Up to 80% of men with an elevated total PSA level of 4.0-10 ng/mL do not have prostate cancer. 14 In men with slightly elevated total PSA (3-10 ng/mL), free PSA helps to discriminate between benign conditions and prostate cancer vnVYJ.
