Fractionated Estrogens Test

The Fractionated Estrogens Test measures individual estrogen hormones, including estrone (E1), estradiol (E2), and estriol (E3), to evaluate reproductive and endocrine health. Abnormal levels may indicate menopause, infertility, ovarian disorders, or pregnancy complications. Doctors use this test to assess hormonal balance, investigate irregular cycles, and guide treatment decisions. It is also valuable for monitoring hormone therapy and evaluating estrogen-related conditions.

Also known as: Estrogens Fractionated LCMSMS

Estradiol, Ultrasensitive

Estriol, LC/MS/MS, Serum

Estrone, LC/MS/MS

Estrone is primarily derived from metabolism of androstenedione in peripheral tissues, especially adipose tissues. Individuals with obesity have increased conversion of androstenedione to Estrone leading to higher concentrations. In addition, an increase in the ratio of Estrone to Estradiol may be useful in assessing menopause in women. Estrone levels may be elevated in patients with polycystic ovarian syndrome and endometriosis. Tests may be used to aid in the diagnosis of an ovarian tumor, Turner syndrome, and hypopituitarism. In males, it may help in the diagnosis of the cause of gynecomastia or in the detection of estrogen-producing tumors.
