The DHEA-sulfate test measures the amount of DHEA-sulfate in the blood. DHEA-sulfate is a weak male hormone (androgen) produced by the adrenal gland in both men and women. DHEA stands for dehydroepiandrosterone.
No special preparation is necessary. However, tell your health care provider if you are taking any vitamins or supplements that contain DHEA or DHEA-sulfate.
How the Test will Feel
When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or sting. Afterward, there may be some throbbing or a slight bruise. This soon goes away.
Why the Test is Performed
This test is done to check the function of the adrenal glands. The adrenal gland is one of the major sources of androgens in women.
The DHEA-sulfate test is often done in women who have male body characteristics (virilism), excessive hair growth (hirsutism), irregular periods, or infertility. It is also done in children who are maturing too early (precocious puberty).
It may also be done in women with pituitary disease or adrenal disease who are concerned about low libido or decreased sexual satisfaction.
Normal blood levels of DHEA-sulfate can differ by sex and age.
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different specimens. Talk to your doctor about the meaning of your specific test results.
Although DHEA-sulfate is the most abundant hormone in the body, its exact function is still not known. In men, the androgenic (male hormone) effect may not be important. In women, DHEA contributes to normal libido and sexual satisfaction. DHEA may also have effects on the immune system.
Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
Other risks associated with having blood drawn are slight but may include:
Fainting or feeling light-headed
Hematoma (blood accumulating under the skin)
Infection (a slight risk any time the skin is broken)
