Advice to patients undergoing follow up PSA (prostate-specific antigen) measurement by their GP - FAQ

Patient information A-Z

What is the PSA blood test?

Prostate-specific antigen (PSA) is a substance produced in the prostate gland. All men have some in their blood. If the amount in the blood is abnormally high, it might indicate that you have a disease in the prostate, which could be cancer or other conditions such as inflammation. PSA is not specific for cancer. In patients already diagnosed and treated for prostate cancer and in patients following normal tests to exclude prostate cancer, it is very valuable to monitor the changes of the PSA value over time.

Why do I need regular PSA tests?

You have either been diagnosed and treated for prostate cancer or have had normal tests to exclude prostate cancer. You may also be on active surveillance where the PSA is used as part of your monitoring process. Having already made several PSA measurements we will be able to use changes in your PSA as an indicator of how things are progressing or if there is a need to reassess and change your management. Please note that PSA can also be affected by many other factor including infections, natural growth of the prostate over time or sexual activity.

What does follow up PSA measurement involve?

PSA is measured by taking a simple blood test. With the results of PSA test and assessment the doctor or nurse will be able to advise you on wether there is a need to change your management.

Where can follow up PSA measurement take place?

This can happen in the hospital or at your GP. It is very important though that you are aware of your PSA reading yourself after every test. You can get this from your nurse or GP or GP practice. This is especially important if you are on active surveillance and/or have been told you have a PSA threshold or level you should not go over.
