What is the Origin of DHEA Sulfate Assessment?

The term combines the abbreviation for the steroid molecule, DHEA, with its sulfated form, which has a much longer half-life, making it a reliable measure, and "assessment," which denotes the clinical measurement process. Its significance in endocrinology arose from its primary production site in the adrenal cortex, making it a valuable, non-pulsatile marker of adrenal androgen production, distinct from gonadal hormones. Levels decline predictably with age, making it a longevity marker.

What is the Mechanism of DHEA Sulfate Assessment?

The assessment mechanism involves quantifying the DHEA-S molecule, which is synthesized from cholesterol in the adrenal cortex and then sulfated to DHEA-S for storage and transport. While DHEA-S itself is largely inert, it can be desulfated back to DHEA and subsequently converted into potent sex steroids like testosterone and estradiol in peripheral tissues. Low levels often reflect age-related decline or adrenal insufficiency, while elevated levels can indicate adrenal hyperplasia or tumors.

DHEA Sulfate Assessment

Meaning

DHEA Sulfate Assessment is a clinical diagnostic procedure that measures the circulating concentration of dehydroepiandrosterone sulfate (DHEA-S) in the blood or saliva. DHEA-S is the most abundant circulating adrenal steroid and serves as a key precursor for both androgens and estrogens. Evaluating its level provides a robust, stable biomarker for adrenal gland function, overall adrenal reserve, and the body’s capacity for steroidogenesis.
