Description: Estradiol, also known as E2, is the most active of the estrogens. For women, it is important to look at the relationship between estradiol and progesterone in evaluating menopausal symptoms such as hot flashes, mood disorders, and aging skin.

In men, high levels of estradiol are associated with abdominal fat, enlargement of the prostate and cardiovascular risk.

In both men and women, low levels of estradiol are associated with osteoporosis.

This test measures the free flowing, unbound, or circulating estradiol.
