The PSA test

• The prostate produces a protein called prostate-specific antigen (PSA). PSA helps to make your semen more liquid. Some PSA leaks into your blood. How much will depend on:
  • Your age – it raises slightly as you get older and your prostate grows
  • The health of your prostate.

   

A PSA test is a simple blood test. This measures the amount of PSA in your blood. The test only takes a few minutes and can be done at your GP surgery.
