Clinical Utility: Estrone is relevant to health and disease states because of its conversion to estrone sulfate, a long lived derivative. Estrone sulfate acts as a reservoir that can be converted as needed to the more active estradiol. Estrone is the only one of the three estrogens which is present in any quantity in post-menopausal women.
