The Estradiol Test measures the amount of a female sex hormone in your blood called estrogen. An estrogen test that helps determine puberty, fertility, menopause, and other conditions. These tests may be called estradiol, estrone (E1), estradiol (E2), estriol (E3), or estrogenic hormone.

• Estrone, also called E1, is the main female hormone made by women after menopause. Menopause is a time in a woman’s life when her menstrual periods have stopped and she can’t become pregnant anymore. It usually starts when a woman is around 50 years old.
• Estradiol, also called E2, is the main female hormone made by nonpregnant women.
• Estriol, also called E3 is a hormone that increases during pregnancy.

The test will determine your estrogen status, evaluate your ovarian function and monitor the follicular development during ovulation.

Estrogen is the hormone that plays a key role in many aspects of a woman’s health, such as bone and reproductive health.
