What is the Origin of DHEA-S Status Evaluation?

The evaluation is a standard practice in clinical endocrinology, stemming from the understanding that DHEA-S is produced primarily by the zona reticularis of the adrenal glands. Its long half-life and high concentration make it a reliable and stable biomarker for chronic adrenal activity. The term itself is derived from the steroid's chemical structure and its clinical utility in assessing hormonal status.

What is the Mechanism of DHEA-S Status Evaluation?

The evaluation quantifies DHEA-S, which is a sulfated prohormone that serves as the primary substrate for the extra-adrenal synthesis of androgens and estrogens in various tissues. Levels are assessed via serum or salivary immunoassay. Low DHEA-S can indicate adrenal insufficiency or advanced aging, while high levels may suggest congenital adrenal hyperplasia or androgen-secreting tumors. The status evaluation directly informs therapeutic decisions regarding adrenal and sex hormone support.

DHEA-S Status Evaluation

Meaning

DHEA-S Status Evaluation is a precise clinical measurement of the circulating concentration of Dehydroepiandrosterone Sulfate, the most abundant adrenal steroid hormone. This evaluation provides a critical snapshot of adrenal cortex secretory function and the systemic pool of precursor steroids available for peripheral sex hormone synthesis. It is utilized to assess adrenal reserve, stress response capacity, and age-related endocrine decline.
