Normal estrogen levels are highest in pre-menopausal women and lower in post-menopausal women, men and children. In pre-menopausal women, Mayo Medical Laboratories defines normal estrone levels as between 17 – 200 picograms per milliliter. Estrogen hormone estradiol ranges between 15-350 picograms per milliliter. Estradiol levels vary throughout a menstrual cycle.
Estrogen tests can measure three different types of estrogen, according to Lab Tests Online. Estrone and estradiol are present in both men and women, and affect puberty, fertility and the development of the nervous system. A third estrogen hormone, estriol, is present only in pregnant women. Serial estriol tests are sometimes used to monitor high-risk pregnancies.
