17-Ketosteroids urine test

  • Definition
    • 17-ketosteroids are substances that form when the body breaks down male steroid sex hormones called androgens and other hormones released by the adrenal glands in males and females, and by the testes in males.

  • How the Test is Performed
    • A 24-hour urine sample is needed. You will need to collect your urine over 24 hours. Your health care provider will tell you how to do this. Follow instructions exactly to ensure accurate results.

  • How to Prepare for the Test

      DO NOT stop taking any medicine before talking to your provider.

  • How the Test will Feel
