Test Description

The Estradiol Blood Test is done to measure the levels of Estradiol, which is a primary component of the estrogen hormone.
What is the Estradiol test?
Estradiol, also known as E2, is one of the four types of estrogen that is produced by ovaries mainly. It is also produced in adrenal glands, placenta, testes, and some other tissues but only in small amounts. The amount of Estradiol in the blood needs to stay accurate for reproductive health. Even the amount increases or decreases more than expected, it can cause many problems such as weak bones, urinary tract infections, and even depression.
Why is the test done?
The doctors will order the Estradiol test if they have a concern about your fertility, puberty, and menopause as well. It can be ordered as well to find out the reasons for specific sexual characteristics in the person. Even though estrogen is a female sex hormone, it is also found in men and has a role to play in the development and growth of male sexual characters. E2 levels affect the functioning of the reproductive system drastically. It influences the following parts of the system:

  • Womb
  • Fallopian tubes
  • Vagina
  • Breasts
  • Libido
  • Erectile function
  • Sperm cells
  • Throughout the reproductive years of women, they have high levels of Estradiol. After they reach menopause, the levels decline to a great extent. And if the Estradiol levels are abnormal, it can cause:
  • A menstrual problem when transitioning to menopause
  • Infertility
  • Gynecomastia or swelling of the male breast tissue
  • Ovarian tumors
  • Breast cancer
  • To prepare for this test, you will be advised not to eat or drink and to avoid other medications as well. During the test, a blood sample will be taken and sent to the labs for testing.
    Test Results:
    The results of the Estradiol test may vary from person to person based on factors like age, sex, or health history. The levels of Estradiol is measured in pictograms per milliliter (pg/ml)
  • In females who have an active menstrual cycle, the normal levels range from 30 to 400 pg/ml
  • In females that have reached menopause, the normal level range is from 0 to 30 pg/ml
  • In males, the normal range of Estradiol is from 10 to 50 pg/ml

  • If the results show that the Estradiol level is low in the blood, it indicates:
  • Ovarian failure
  • Menopause
  • Low estrogen level due to rapid weight loss
  • Low pituitary hormones
  • Pregnancy failure
  • Turner syndrome, a chromosomal condition that causes infertility
  • If the test results are high, it signals the following conditions:
  • Hyperthyroidism
  • Liver damage
  • Gynecomastia
  • Tumor in ovaries, testicles, or adrenal glands
  • Even the pregnancy and the menstrual cycle can affect the result causing the Estradiol levels to rise and fall. Pregnancy results in a significant increase in the Estradiol level. And during the menstrual cycle, the Estradiol levels are high when the woman is ovulating and lowest during menstruation.
