Estradiol (E2) is the primary form of estrogen in women and is crucial for the regulation of the menstrual cycle, fertility, and the development of secondary sexual characteristics. This test measures estradiol levels in the blood to assess ovarian function, diagnose menstrual irregularities, and evaluate conditions like polycystic ovary syndrome (PCOS), menopause, or ovarian tumors. It can also be used to monitor hormone replacement therapy or evaluate fertility treatment effectiveness.

Clinical Applications:

Reproductive health and ovarian function: Estradiol is the predominant form of estrogen in women and plays a crucial role in regulating the menstrual cycle, fertility, and the development of secondary sexual characteristics.

Assessment of ovarian reserve: Low levels may indicate menopause or ovarian dysfunction, while elevated levels can suggest ovarian tumors or hormone replacement therapy.

Endocrine disorders: Used in diagnosing and monitoring conditions like polycystic ovary syndrome (PCOS), premature ovarian failure, and other hormone imbalances.

Menstrual irregularities: It is helpful in investigating abnormal menstrual cycles or unexplained infertility.
