Fractionated Estrogens Test

Estrogens are a group of hormones best known for regulating the maturation of sex organs and the development of secondary sex characteristics in biological females.  The Fractionated Estrogens Test individually measures the three primary types of estrogen – Estrone (E1), Estradiol (E2), and Estriol (E3) – to provide a comprehensive picture of your hormone health.  Each form plays a unique role: 

  1. Estrone (E1) is a weaker estrogen that becomes the dominant form after menopause and may be elevated in estrogen dominance or adipose tissue-related hormone imbalances. 
  1. Estradiol (E2) is the most potent estrogen and is essential during the reproductive years for regulating the menstrual cycle, mood, bone health, and fertility. 
  1. Estriol (E3) is the gentlest form, primarily produced during pregnancy, and offers protective effects for tissues such as skin, bladder, and the vaginal lining. 

Unlike a standard estrogen test, which only provides a total value, this test breaks down each form of estrogen.  The results give in-depth insight into imbalances that may be contributing to symptoms like PMS, hot flashes, weight changes, fatigue, or fertility challenges.  This test provides a more precise analysis that can aid in more personalized treatment.  It may be especially beneficial to those receiving menopause care or hormone replacement therapy.
