Prostate-Specific Antigen (PSA) Blood Test
What Does an Elevated PSA Level Mean? continued...
Your PSA level can also be affected by other factors:
- Age. Your PSA will normally go up slowly as you age, even if you have no prostate problems.
- Medications. Some drugs may affect blood PSA levels. Tell your health care provider if you are taking finasteride (Proscar or Propecia) or dutasteride (Avodart). These drugs may falsely lower PSA levels typically by half of what it would normally be.
If your PSA level is high, your doctor may recommend that you get a prostate biopsy to test for cancer.
Alternative PSA Testing
There are some new PSA tests that may help you and your health care provider determine if you need a biopsy. You should know that doctors do not always agree on how to use or analyze the results of these additional tests.
