Dehydroepiandrosterone

DHEA changes to DHEA-S (DHEA-sulfate) in your adrenal glands and liver. Your body converts DHEAS into androgens (testosterone and androstenedione) and estrogen. Males make more testosterone, while females make more estrogen, but both the genders produce and use these hormones. DHEAS is critical for the development of male sexual characteristics during puberty and for reproduction in both the genders. DHEAS levels tend to peak around puberty and then naturally decline with age.

Your doctor may suggest a Dehydroepiandrosterone test along with other hormone tests  if there are symptoms that may suggest an adrenal disorder, adrenal tumor or another problem. Also, it is often done for women who have signs and symptoms such as no menstrual periods and infertility and when a girl or woman has symptoms related to developing masculine physical characteristics. Infants or children with differences in sex development may also need a DHEAS test. Additionally, the test can be done when young boys show signs of precocious puberty. 

Imbalances in DHEA levels can indicate various health problems, including adrenal dysfunction, hormonal imbalances, or conditions like Polycystic ovary syndrome (PCOS), Addison’s disease etc.

An overnight fasting is preferred for the Dehydroepiandrosterone test but is not mandatory. Inform your doctor about all the medications or supplements that you may be taking as these may affect your test results, potentially requiring adjustments or temporary discontinuation before this test. 

Lab test results may vary across laboratories. The interpretation of the test results requires expert guidance. Therefore, don't self-medicate solely based on these results. Always consult the doctor to understand your test results correctly.
