When is an Estradiol Ultrasensitive test ordered?

Tests for estradiol for women and young girls may be ordered if:

  • The development of a girl's sex organs might occur sooner or later than predicted.
  • After menopause, a woman may experience symptoms such as abnormal vaginal bleeding or irregular or absent menstrual cycles.
  • When a woman is unable to conceive, a series of estradiol readings taken over the course of her menstrual cycle may be used to track follicle development before using in vitro fertilization procedures
  • A woman is experiencing menopause symptoms such as hot flashes, night sweats, sleeplessness, and/or irregular or absent menstrual cycles.
  • If a menopausal woman is on hormone replacement therapy, her doctor may order estrone levels on a regular basis to check her progress.

Men and young boys may be subjected to estradiol testing if:

  • A boy's puberty is delayed, as evidenced by slow or delayed growth of testicles and penis, as well as a lack of deepening of voice or growth of body hair.
  • Signs of feminization, such as larger breasts.

What does an Estradiol Ultrasensitive blood test check for?

Estradiol, or E2, is a component of Estrogen that is present in the blood. For women, Estradiol is something that should be produced naturally, and the body produces larger amounts of Estradiol during puberty and it fluctuates throughout the menstrual cycle. Estradiol is most prominent in women of reproductive age. Low levels are common in girls who have not yet had their first menstrual cycle and in women after their reproductive age.

Lab tests often ordered with an Estradiol Ultrasensitive test:

  • Estrogen, Total, Serum
  • Estriol
  • Estrone
  • Testosterone Free and Total
  • Sex Hormone Binding Globulin
  • FSH
  • LH
  • Progesterone

Conditions where an Estradiol Ultrasensitive test is recommended:

  • Infertility
  • Menopause
  • Polycystic Ovarian Syndrome
  • Hormone Imbalance
  • Premature, delayed, or abnormal development of sex organs

Commonly Asked Questions:

How does my health care provider use an Estradiol Ultrasensitive test?

Estrogen tests are used to detect a deficit or excess of estrogen in a woman, as well as to aid in the diagnosis of a range of illnesses linked to this imbalance. They may also be ordered to monitor the health of the growing fetus and placenta during pregnancy, as well as to help predict the timing of a woman's ovulation. Estrogen testing can be used to detect a hormone excess and its origin in men.

In the case of girls and women

Estradiol testing may be requested for the following reasons:

  • Diagnose early-onset puberty, which occurs when a girl develops secondary sex traits much earlier than anticipated, or late puberty, which occurs when a female develops secondary sex characteristics or begins menstruation later than predicted.
  • Examine menstrual irregularities such as the absence of menstrual periods, infertility, and unusual vaginal bleeding.
  • Evaluate ovary function and look for signs of ovarian failure.
  • Serial measurements of estradiol can be used to track follicle development in the ovary in the days leading up to in vitro fertilization.
  • Keep track of any hormone replacement therapy you're getting to help with your fertility.
  • Keep track of menopausal hormone replacement medication, which is used to treat symptoms caused by estrogen insufficiency.
  • Identify cancers that produce estrogen.
  • As with breast cancer, keep an eye on anti-estrogen therapy.

Boys and men may be subjected to estradiol testing in order to:

  • Assist in the diagnosis of delayed puberty
  • Assist in determining the cause of larger breasts or other feminization indications.
  • Detect an excess of relative estrogen due to a testosterone or androgen deficit.
  • Identify cancers that produce estrogen.

What do my Estradiol test results mean?

Estradiol is one of the three Estrogens that have a large impact on the women's body throughout the menstrual cycle. When these hormones are too high or too low, it could cause irregular bleeding, infertility, complications with menopause, and delayed or premature puberty. Out of range levels can also be indicative of an ovarian condition such as PCOS. It is important to note that these values will fluctuate throughout a woman's cycle. The Estrogen hormones work together and if one is out of range, the others may also be out of range. It is recommended to follow up with a licensed healthcare professional to determine the best treatment if need.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
