Estradiol test: measure your estrogen level

• Measures your estradiol level in the blood, the most important and active form of estrogen.
• Provides insight into symptoms such as irregular menstruation, fertility problems, menopausal symptoms, or suspected estrogen dominance.
• Standalone test: no extensive package needed if you want to specifically check your estrogen level.
• Results assessed by BIG-registered physicians, with a clear explanation of your result.

Do you have a regular cycle and are you not yet in menopause? Then preferably have blood drawn between cycle day 2 and 4, the early follicular phase, for the most reliable comparison with reference values. Are you in menopause or using hormonal contraception? Then the cycle day plays a smaller role. A healthcare professional draws the blood from a vein in your arm; this usually takes only a few minutes.

What does the estradiol test measure?

This test measures your estradiol level in the blood: the most biologically active form of estrogen, and the form referred to in practice when you "have your estrogen tested." Estradiol is primarily produced in the ovaries and plays a key role in your menstrual cycle, fertility, and bone health. Men also produce estradiol, although in much smaller quantities.

Who is the estradiol test for?

This standalone estradiol test is for anyone who wants to know specifically where their estrogen level stands. For women, the test can help identify the cause of irregular menstruation, fertility problems, menopausal symptoms such as hot flashes, or a suspicion of estrogen dominance (too much estrogen relative to progesterone). Do you use hormonal contraception or hormone therapy? Periodic monitoring can then help track the effect. Men can also have this test done, for example if they suspect a hormonal imbalance. You do not need to have any symptoms to book this test.

When should you choose the estradiol test rather than a complete blood test?

Do you only want to check your estradiol, for example to monitor your fertility or to specifically confirm a suspicion? Then this standalone estradiol test is the fastest and most affordable option. Do you want a broader picture of your health all at once, including cardiovascular values, liver, kidneys, and blood status? Then the Essential Women's Blood Test is the more logical choice: in addition to estradiol, that package contains progesterone and vitamin B12, along with 32 other markers for a complete picture.

How does it work?

You order the test online and make an appointment at a blood collection location near you. A healthcare professional draws the blood, and within 2 to 5 working days you will receive your results clearly presented in our portal, with clear explanations and assessed by our doctors.

Frequently Asked Questions

Do I need a referral for the estradiol test?

No, you do not need a referral from your GP. You order the test directly from Zample and then activate your own digital request.

What is the difference between estradiol and estrogen?

Estrogen is the collective name for a group of hormones. Estradiol is the most important and active form of this, and the form that is measured in practice when you have your estrogen tested. This test therefore specifically measures your estradiol level.

When in my cycle is it best to have the estradiol test performed?

Do you have a regular cycle and are you not yet in menopause? Then preferably have blood drawn between cycle day 2 and 4, the early follicular phase, for the most reliable comparison with reference values. Are you in menopause, pregnant, or using hormonal contraception? Then the cycle day plays a smaller role.

What does a low estrogen level mean?

A low estradiol value can indicate reduced ovarian function, for example due to menopause or premature ovarian insufficiency. Symptoms associated with this may include fatigue, mood swings, and dry mucous membranes. Always discuss an abnormal result with your GP.

What does a high estrogen level (estrogen dominance) mean?

An elevated estradiol value can indicate excessive ovarian activity or, in men, liver problems. Estrogen dominance occurs when estrogen is too high relative to progesterone. In this case too, discussing this with your GP is important for the correct next steps.

Can I also take the estradiol test as a man?

Yes. Men also produce estradiol, albeit in much smaller quantities than women. In men, the hormone plays a role in sperm production and maintaining healthy bone mass. A significantly elevated value in men can sometimes be associated with liver problems.

What is the difference between the estradiol test and a test for all female hormones?

This test specifically measures estradiol, the main form of estrogen. Do you want a broader hormonal picture, for example including progesterone or FSH and LH for ovarian function? Then a more extensive blood test with multiple hormones is a more logical choice.

How quickly will I receive the results of my estradiol test?

Usually within 2 to 5 working days after your blood draw, clearly presented in our portal and assessed by a BIG-registered physician.

Can I combine an estradiol test with a more extensive blood test?

Yes. If you prefer a comprehensive overview of your health all at once, the Essential Women's Blood Test, for example, is a logical choice: in addition to estradiol, that package includes progesterone, vitamin B12, and a complete health overview.

Is the estradiol test useful during menopause?

Yes. Estradiol levels drop around menopause, and this drop is associated with symptoms such as hot flashes and an increased risk of osteoporosis. The test provides a concrete starting point for discussing these symptoms further with your doctor.
