No! Consider it as a preliminary test which if above the normal range for the age of a man suggests PCa and a number of other things might be responsible and require further investigation. However, as the PSA level increases considerably, so does does the chance of PCa being responsible so that when 100+ is reached the chance of it being PCa is almost certain. But by the time such a reading is reached the chances are that the PCa is advanced. Conversely, there are a smaller number of men who exhibit a PSA reading within normal range but are still found to have PCa, So the PSA test, particularly as a tool for diagnosing PCa, is not a very good one but in some cases supports further tests. Even good scans do not always reveal the presence of PCa. For the majority of men it is a biopsy that enables a consultant to confirm the presence of cancer cells and even here the common TRUS biopsy can miss tumours. A template biopsy is more likely to find any cancer.
So in most cases it's really a matter of considering all these tests along with any symptoms a man may have (although men do not always show problems or if they do it could be due to something else.
I don't know whether you have had a urine dip test or better still a urine culture test done as a Urinary Infection could be responsible for your problem and I would suggest you get this possibility ruled out first.
