Prostate-Specific Antigen - PSA Test

This test measures the blood level of a protein produced by the prostate gland.

This test measures the blood level of a protein produced by the prostate gland.

This blood test measures the level of a protein produced by the prostate gland. Prostate cancer (and some non-cancerous conditions) may cause an elevation of the prostate-specific antigen (PSA).

  • A PSA test is used to screen for prostate cancer. However, its use is controversial, so you should discuss with your healthcare provider whether obtaining this test is right for you.
  • It may also be used to monitor the course of prostate cancer or find out how well a man responds to treatment.

The blood sample is usually taken by placing a needle in a vein in the arm. In some cases the sample may be taken by pricking a finger.

  • No special preparation is needed for this test.
  • Your healthcare provider may recommend that you have the PSA test either before or at least 48 hours after a digital rectal exam. This may help prevent a falsely high result.
  • This care path's costs do not include the charge to draw blood from a vein (venipuncture).
  • There will only be one charge to draw blood, even if multiple tests are being performed on the samples that are taken.

What should I ask my healthcare provider before having this test?

  • Is there any special preparation for the test? (If so, get clear instructions on what you need to do.)
  • What is the reason for the test? Will the test results change my treatment plan? If not, do I need the test?
