An estradiol (E2) test measures the levels of the hormone estradiol in your blood. It is primarily a female sex hormone that is produced by the ovaries, breasts, and adrenal glands. Usually, healthcare providers might recommend the E2 test in relation to a female's fertility, puberty, and menopause. It is during their reproductive years that women usually have their highest levels of estradiol. This hormone is considered to be one of the best markers for ovarian function.
The other names are serum E2 and estrogen.
There is only one parameter.
An estradiol (E2) test analyses the levels of estradiol in the blood.Estradiol(E2) is a form of estrogen hormone that plays an important role in the function and development of reproductive organs and in the formation of secondary sex characteristics in females. It controls the menstrual cycle in women along with progesterone. Other functions of estrogen, along with progesterone, include the growth of breasts and the uterus. Estrogen hormone is also found in men. It controls growth and metabolism in both males and females. In men, estradiol is produced in the testicles, while in premenopausal women it is produced in the ovaries. In postmenopausal women, estradiol (E2) is converted into estrone. Estradiol(E2) is present at high levels in non-pregnant and premenopausal women. Itis depending upon the age of the woman and her reproductive status, the values of estradiol vary. It is also considered to be one of the good markers as regards to ovarian function.
At birth, the levels of estradiol(E2) are high, but the levels will fall within a few days and become minimal during early childhood. As puberty approaches, the amount of estradiol rises. During the menstrual cycle, levels will vary depending on the ongoing menstrual cycle phase. During menopause, levels of estradiol fall as the production by the ovaries decreases.
Estradiol (E2) and estrone (E1) testing in girls and women might be recommended if:
Girls' sex organs develop earlier or later than normally expected.
A woman has symptoms such as abnormal vaginal bleeding after menopause or an abnormal lack of menstrual cycles.
A woman is experiencing infertility. A series of estradiol measurements over the course of a woman’s menstrual cycle might be done to monitor follicle development prior to in-vitro fertilisation techniques.
A woman is having symptoms of menopause, including hot flashes, night sweats, insomnia, and irregular or absent menstrual periods.
A menopausal woman is taking hormone replacement therapy; her health practitioner might periodically order estrone levels to monitor treatment.
Estriol (E3) testing in women can be recommended:
During pregnancy, a healthcare practitioner might order serial estriol samples to look for a trend, whether there is an increase or fall in the estriol level over time.
Unconjugated estriol is often analysed in the 15th to 20th week of gestation as part of the triple/quad screen.
Estradiol (E2) and estrone(E1) testing in boys and men might be recommended when:
A boy has delayed puberty, characterised by delayed development of muscle mass, lack of deepening of the voice or growth of body hair, and slow or delayed growth of testicles and penis.
A man shows signs of feminisation, such as enlargement of the breasts.
No special preparation is required. Fasting is not required.
This test requires a blood sample.
A healthcare provider, who is also called a phlebotomist, usually performs blood draws, including those for estradiol (E2) tests, but any healthcare provider trained in drawing blood can perform this task. These samples are sent to a lab where a medical laboratory scientist prepares the samples and performs the tests on analysers or manually.
You may expect to experience the following during the blood test or ablood draw:
You have to sit comfortably on the chair, and a healthcare providerwill check your arms for an easily accessible vein. It is the innerpart of your arm on the other side of your elbow.
Once the phlebotomist has located a vein, they will clean anddisinfect the area with an alcohol swab.
They will insert a needle into your vein to draw a blood sample. Theymay feel like a small pinch.
After they insert the needle, the required amount of blood is drawninto a test tube.
When they have drawn enough blood for the test, they’ll remove theneedle and hold a cotton ball or gauze on the pricked site to stop anybleeding.
They apply a band-aid over the pricked site, and the blood collectionis finished.
This process takes less than five minutes.
Once the phlebotomist has collected the blood sample then it will be sentto the laboratory for processing. When the reports are ready, yourhealthcare provider will share the results with you.
These blood tests are very common, and they don’t carry any significantrisks. You can have a slight pain like an ant bite when the needle getsinserted, and a small bruise might develop there.
This report is available via email or WhatsApp within 6 hours after thecollection of the blood sample.
Normal Estradiol (E2) results depend upon the sex and age of the personbeing tested. In women, it also depends upon their menstrual cycle orwhether they are pregnant or not. Reference ranges will vary betweenlaboratories, both in normal values listed and in units used.
Increased or decreased levels of estradiol (E2) are seen in manymetabolic conditions. Care must be used in the interpretation of estrone,estradiol (E2), and estriol results because the levels vary on aday-to-day basis and throughout a woman’s menstrual cycle.
A healthcare practitioner who is monitoring a woman’s hormones will belooking at trends in levels, rising or lowering over time in conjunctionwith the menstrual cycle or pregnancy, rather than evaluating singlevalues.
Below are conditions in which one might see an increase or decrease inestradiol (E2) levels.
Increased levels of estradiol (E30 or estrone (E1) are seenin:
Girls and Women:
Early puberty
Tumours of the ovary or adrenal glands
Boys and Men:
Enlarged breasts (gynecomastia)
Tumours of the testicles (testicular cancer) or adrenal glands
Delayed puberty
Both Women and Men:
Hyperthyroidism
Cirrohosis
In women, decreased levels of estradiol (E2) are seen in
Turner syndrome: an inherited condition in women caused by a missingor abnormal X chromosome and characterised by underdeveloped femalesex characteristics.
Low levels of pituitary hormones (hypopituitarism)
Dysfunction of the ovaries (female hypogonadism)
Failing pregnancy (estriol)
Eating disorders such as anorexia nervosa
After menopause (estradiol)
A polycystic ovary syndrome (PCOS, also called stein-Levanthalsyndrome)
Extreme endurance exercise
Normal ranges might vary slightly among different laboratories. Some ofthe labs use different measurements or may test different samples. Speakto the doctor about the meaning of your specific test results.
