Estradiol - test

An estradiol test measures the amount of a hormone called estradiol in the blood. Estradiol is the most important form of estrogen found in the body. Most of it is made in and secreted from the ovaries, adrenal cortex, and placenta.

Estradiol is responsible for the growth of the female uterus, Fallopian tubes, and vagina. It promotes breast development and the growth of the outer genitals. The hormone plays a role in the distrubtion of body fat in women and stops the process of growing taller.
