DHEAS Blood Test

Last updated Sept. 9, 2018

The DHEAS Blood Test is a test to assess the levels of DHEAS in circulation.


What are the other Names for this Test? (Equivalent Terms)

  • Dehydroepiandrosterone Sulfate Blood Test
  • DHEA Sulfate Blood Test
  • DHEA-SO4 Blood Test 

What is DHEAS Blood Test? (Background Information)

  • Dehydroepiandrosterone sulfate (DHEAS) is a metabolite of dehydroepiandrosterone (DHEA), a major male sex hormone. DHEAS Blood Test is used as a screening blood test to diagnose adrenal gland cancers
  • DHEA is mostly produced in the adrenal glands with a small amount secreted by the ovaries and testes. It is made alongside cortisol. The adrenal glands (also known as suprarenal glands) are situated atop the kidneys. The sulfated form of DHEA, called DHEAS, is only produced by the adrenal glands
  • The adrenal glands are stimulated by adrenocorticotropic hormone (ACTH) and prolactin, produced by the pituitary gland. It is in turn stimulated by corticotropin-releasing hormone (CRH) produced by the hypothalamus of the brain
  • DHEA can be further converted into other sex hormones, such as testosterone and estrogen. It is one of the hormones responsible for secondary sex characteristics, like breast development and body hair
  • Tumors of the adrenal gland may result in overproduction of DHEA. In women, this may cause the development of male secondary sex characteristics and menstrual abnormalities. It may also cause masculinization of children
  • The DHEAS Blood Test is a test to assess the levels of DHEAS in circulation. Since, DHEAS is produced only in the adrenal glands, this test determines if the origin of male sex hormone overproduction is the adrenal glands, as opposed to the testes or ovaries
