Notes:

PSA is more sensitive and specific for carcinoma of the prostate than prostatic Acid Phosphatase. Levels may correlate with tumour bulk and clinical stage, but significant elevations have also been seen in benign prostatic hypertrophy (BPH).

PSA values in the 4 - 20 mg/L range are not helpful in discriminating between BPH and carcinaoma of the prostate.

Increased levels of PSA occur with increasing age. This is not currently reflected in our reference range.
