ESTRADIOL/OESTROGEN (E2)

The estradiol (E2) test measures the level of estradiol, a form of estrogen, in the blood. Estradiol is a key hormone involved in the regulation of the menstrual cycle, reproductive system, and secondary sexual characteristics. This test is used to assess ovarian function, diagnose hormonal imbalances, and monitor hormone replacement therapy. Elevated estradiol levels can indicate conditions such as ovarian tumors or hyperestrogenism, while low levels suggest menopause or ovarian insufficiency. The estradiol test is valuable for managing reproductive health, diagnosing endocrine disorders, and guiding treatment decisions.
