What is the Origin of DHEAS Levels?

The term is an abbreviation for Dehydroepiandrosterone Sulfate, with "Levels" referring to the measured concentration in the blood. DHEA was first isolated in the 1930s, and its sulfated form, DHEAS, was later recognized as a key endocrine biomarker due to its long half-life and high plasma concentration. Its clinical relevance in assessing adrenal function and its relationship to the aging process became prominent in the latter half of the 20th century.

What is the Mechanism of DHEAS Levels?

DHEAS is synthesized almost exclusively by the adrenal cortex under the regulation of Adrenocorticotropic Hormone (ACTH), serving as the stable precursor molecule for both androgens and estrogens in peripheral tissues. The sulfated form is relatively inactive but provides a large, stable reservoir that can be readily converted back to the active DHEA and subsequently to other active sex steroids as needed by the body. Assessing its level helps clinicians understand the upstream production capacity of the adrenal axis and the substrate availability for downstream hormonal pathways.

DHEAS Levels

Meaning

A quantitative measurement of the concentration of Dehydroepiandrosterone Sulfate (DHEAS) in the serum, which functions as the most abundant circulating adrenal steroid precursor in the human body. Clinically, DHEAS levels serve as an important and stable biomarker for adrenal gland function, reflecting overall hormonal reserve and vitality, given that its production reliably declines with chronological age. This assessment is used to evaluate adrenal androgen status and offers critical insights into the biological aging process.
