The PSA (prostate specific antigen) prostate blood test is much used in Urology to help in the diagnosis of prostate cancer and other urological symptoms in men. It is a controversial test with a number of potential limitations.
There have been a number of attempts to try and improve the accuracy of this test and researchers in Austria, based at the Medical University of Vienna and Vienna General Hospital have combined the PSA test with newer molecular methods to try and improve the accuracy of PSA.
My view is that PSA should always be interpreted in an individual context in combination with an assessment of the patient’s symptoms, findings on examination, and increasingly the use of imaging such as an MRI scan. Research for a replacement for PSA goes on but until then it remains an extremely useful test if it is interpreted appropriately.
