What is an estrogen test?

An estrogen test measures the level of estrogens in the blood or urine. Estrogen can also be measured in saliva using at-home test kit. Estrogens are a group of hormones that play a key role in the development of female physical features and reproductive functions, including the growth of breasts and the uterus, and regulation of the menstrual cycle. Men also make estrogen but in much smaller amounts.

There are many types of estrogens, but only three types are commonly tested:

  • Estrone, also called E1, is the main female hormone made by women after menopause. Menopause is a time in a woman’s life when her menstrual periods have stopped and she can’t become pregnant anymore. It usually starts when a woman is around 50 years old.
  • Estradiol, also called E2, is the main female hormone made by nonpregnant women.
  • Estriol, also called E3 is a hormone that increases during pregnancy.

Measuring estrogen levels can provide important information about your fertility (the ability to get pregnant), the health of your pregnancy, your menstrual cycle, and other health conditions.

Other names: estradiol test, estrone (E1), estradiol (E2), estriol (E3), estrogenic hormone test

What is it used for?

Estradiol tests or estrone tests are used to help:

  • Find out the reason for early or late puberty in girls
  • Find out the reason for late puberty in boys
  • Diagnose menstrual problems
  • Find out the cause of infertility (the inability to get pregnant)
  • Monitor infertility treatments
  • Monitor treatments for menopause
  • Find tumors that make estrogen

An estriol hormone test is used to:

Why do I need an estrogen test?

You may need an estradiol test or an estrone test if you:

  • Are having trouble getting pregnant
  • Are a woman of childbearing age who is not having periods or having abnormal periods
  • Are a girl with early or delayed puberty
  • Have symptoms of menopause, including hot flashes and/or night sweats
  • Have vaginal bleeding after menopause
  • Are a boy with delayed puberty
  • Are a man showing female characteristics, such as the growth of breasts

If you are pregnant, your health care provider may order an estriol test between the 15th and 20th week of pregnancy as part of a prenatal test called a triple screen test. It can find out if your baby is at risk for a genetic birth defect such as Down syndrome. Not all pregnant women need to get an estriol test, but it is recommended for women who have a higher risk of having a baby with a birth defect. You may be at a higher risk if you:

What happens during an estrogen test?

Estrogens can be tested in blood, urine, or saliva. Blood or urine is usually tested in doctor’s office or lab. Saliva tests can be done at home.

For a blood test:

A health care professional will take a blood sample from a vein in your arm, using a small needle.

After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

For a urine test:

Your health care provider may ask you to collect all urine passed in a 24-hour period. This is called a 24-hour urine sample test. For this test, your health care provider or a laboratory professional will give you a container to collect your urine and instructions on how to collect and store your samples. A 24-hour urine sample test generally includes the following steps:

  • Empty your bladder in the morning and flush that urine down. Do not collect this urine. Record the time.
  • For the next 24 hours, save all your urine passed in the container provided.
  • Store your urine container in the refrigerator or a cooler with ice.
  • Return the sample container to your health provider’s office or the laboratory as instructed.

For an at-home saliva test, talk your health care provider. He or she can tell you which kit to use and how to prepare and collect your sample.

Will I need to do anything to prepare for the test?

You don’t need any special preparations for an estrogen test.

Are there any risks to the test?

There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.

There is no known risk to a urine or saliva test.

What do the results mean?

If your estradiol or estrone levels are higher than normal, it may be due to:

If your estradiol or estrone levels are lower than normal, it may be due to:

If you are pregnant and your estriol levels are lower than normal, it may mean your pregnancy is failing or that there is a chance your baby might have a birth defect. If the test shows a possible birth defect, you will need more testing before a diagnosis can be made.

Higher levels of estriol may mean you will be going into labor soon. Normally, estriol levels go up about four weeks before you start labor.

If you have questions about your results, talk to your health care provider.
