Estrone Sulfate

Estrone sulfate (E1-S) is a sulfate derivative of estrone, and is the most abundant form of circulating estrogens in both men and non-pregnant women.

Estrone sulfate itself does not have direct estrogenic activity, it may be viewed rather as a slowly-metabolized estrogen reservoir. It is determined mainly to monitor female hormone replacement therapy in postmenopausal women.
