Additional information
PSA is not considered suitable for screening the general population for disease but men over 50 are able to request the test after discussion with their GP.
PSA measurement should be followed up by a DRE. PSA increases with clinical disease stage: PSA >50 ug/L is indicative of metastatic disease with >100 ug/L suggesting bony metastases. PSA is also useful for monitoring treatment of prostatic carcinoma. It is useful to measure PSA post prostatectomy with elevated concentrations being indicative of residual disease. It is also useful for predicting tumour recurrence months before any clinical signs. False negative PSA results are seen in 9% cancer patients.
The minimum repeat interval for PSA is one month.
PSA can be increased following DRE, UTI etc.
