Used in research settings to measure dehydroepiandrosterone sulfate (DHEA-S) levels in human serum or plasma samples. This immunoassay kit enables scientists to study adrenal gland function, evaluate disorders related to adrenal hyperactivity or insufficiency, and investigate hormonal imbalances linked to aging, stress, fertility, and metabolic conditions. Commonly applied in endocrinology studies, clinical research, and pharmaceutical development to assess the role of DHEA-S as a biomarker for various physiological and pathological processes.
