DLO Direct Self-Ordered Lab TestsPSA (prostate‐specific antigen) is a protein made by the cells of the prostate. The routine PSA test measures the amount of prostate‐specific antigen in the blood. Rising or changing levels of PSA may be a sign of a prostate problem, perhaps as serious as cancer.

How common is prostate cancer?

After skin cancer, prostate cancer is the most common cancer among men and is the second leading cause of cancer death behind only lung cancer, according to the American Cancer Society. Prostate cancer occurs mainly in older men as approximately 6 cases in 10 are diagnosed in men aged 65 or older, and it is rare before age 40. The average age at the time of diagnosis is about 66. While about 1 in 7 men will be diagnosed with prostate cancer during his lifetime, it can often be treated successfully.

What are the symptoms of prostate cancer?

Early prostate cancers usually don’t cause symptoms, but more advanced cases may exhibit the following:

  • Urinary issues
  • Sexual problems



To order your own lab tests, you just need to follow these three easy steps:

  1. Complete a lab order form for your test online and print it out to take with you to the DLO Patient Service Center. Follow the instructions on the laboratory test order form if fasting is required for the testing you are ordering.

It is always recommended you meet with a healthcare provider to determine what your laboratory test results mean to you. Your healthcare provider will review all of your test results and, combined with your health history, will be able to provide an accurate picture of your health status.

If any of your results were high: If your result was abnormally high, there are benign conditions to consider (enlarged prostate, prostate inflammation, kidney retention) in addition to the presence of prostate cancer. Please note that PSA levels increase with age even in cancer‐free men, and an elevated PSA level does not necessarily mean cancer. It is important to share your PSA results with your healthcare provider so that your results can be further investigated. Generally, the results from a PSA blood test and a digital rectal exam (DRE) along with your age are considered when estimating the level of risk for prostate cancer. As with any abnormal results, it’s important that you discuss their implications with your healthcare provider.

If your results were within normal range: If your results were within the normal PSA range, you should consult with your healthcare provider for recommendations on when you should be tested again. The American Cancer Society suggests men who are not at risk for prostate cancer should begin annual testing at age 50. African American men and men with a close relative who has had prostate cancer should begin annual testing at age 45. Your healthcare provider is best suited to advise you on a timetable for all screening tests.
