What is Estradiol E2?
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 released from the ovaries, adrenal cortex, and the placenta, which forms during pregnancy to feed a developing baby. This test is used to check the function of the ovaries, placenta, or adrenal glands. Lower-than-normal levels may indicate Turner syndrome, ovarian failure, low estrogen production related to rapid weight loss or low body fat, and other conditions
