17-Ketosteroids urine test

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.

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

Your provider will ask you to temporarily stop any medicines that may affect the test results. Be sure to tell your provider about all the medicines you take. These include:

  • Antibiotics
  • Aspirin (if you are on long-term aspirin)
  • Birth control pills
  • Diuretics (water pills)
  • Estrogen

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

How the Test will Feel

The test involves normal urination. There is no discomfort.

Why the Test is Performed

Your provider may order this test if you have signs of a disorder associated with abnormal levels of androgens.

Normal Results

Normal values are as follows:

  • Male: 7 to 20 mg per 24 hours
  • Female: 5 to 15 mg per 24 hours

Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your doctor about the meaning of your specific test results.

What Abnormal Results Mean

Increased levels of 17-ketosteroids may be due to:

Decreased levels of 17-ketosteroids may be due to:

  • Adrenal glands not making enough of their hormones (Addison disease)
  • Kidney damage
  • Pituitary gland not making enough of its hormones (hypopituitarism)
  • Removal of the testicles (castration)

Risks

There are no risks with this test.

  • Urine sample - illustration

    A clean-catch urine sample is performed by collecting the sample of urine in midstream. Men or boys should wipe clean the head of the penis. Women or girls need to wash the area between the lips of the vagina with soapy water and rinse well. A small amount of urine should initially fall into the toilet bowl before it is collected (this clears the urethra of contaminants). Then, in a clean container, catch about 1 to 2 ounces of urine and remove the container from the urine stream. The container is then given to the health care provider.
