PSA Test Results

The PSA test is a blood test used to measure a substance called prostate specific antigen in the blood. It is used as a screening tool for prostate cancer.

In a healthy male, the PSA level should be less than 4 nanograms per milliliter of blood. Anything higher than 4 can indicate prostate cancer.

Keep in mind that PSA tests are notorious for producing false positives. Other tests such as a biopsy or digital rectal exam may be performed to further evaluate the prostate for cancer.

There are other factors that can elevate the PSA levels, such as:

  • ejaculation (no ejaculation at least two days prior to test)
  • PSA levels can naturally increase with age
  • inflammation of the prostate gland
  • non cancerous enlargement of the prostate
