PSA, Free and Total

This is a screen for antigens that can be markers of prostate cancer, for people born with testes. If you have testes masses, genital pain, growths or other changes in your testes, they should always be assessed by a healthcare provider. People born with testes that are on estrogen therapy can have artificially lower prostate screening antigens and may need a manual prostate exam at a visit for the most accurate prostate cancer screening.
