What does a DHEA-S test primarily assess?

The DHEA-S test primarily assesses the levels of dehydroepiandrosterone sulfate, a hormone produced by the adrenal glands. Elevated levels of DHEA-S can indicate the presence of adrenal tumors such as adrenocortical carcinoma, as these tumors often produce excess hormones. This test is particularly valuable in distinguishing primary adrenal disorders from other conditions that may affect hormone levels, providing important insights into adrenal function and potential pathology.

While DHEA-S can have implications for various conditions such as polycystic ovary syndrome (PCOS), it is not directly used to mimic its symptoms. Additionally, its role does not extend to evaluating thyroid hormone levels or testing for ovarian cysts, as those assessments require different diagnostic tests and approaches. Understanding the specific function of the DHEA-S test helps direct appropriate evaluation and management of adrenal-related disorders.
