Estradiol is a natural estrogen present in both women and men. Because estradiol levels reflect follicular maturation, clinicians commonly order this test in women to assess ovulatory status. The measurement of estradiol also has been used as a valuable tool in the assessment of sexual development in children, anovulation and/or amenorrhea, polycystic ovary syndrome, and causes of infertility and menopause. Support informed clinical decision making for patients experiencing these conditions with the Access Estradiol assay. Benefit from the assay’s state-of-the-art sensitivity for greater confidence as well as its broadest dynamic measuring range for increased efficiency.
