What's this test for?

This test is ideal if you're experiencing irregular or absent menstrual cycles, unexplained weight changes, mood swings, or difficulty getting pregnant. It measures estradiol, the primary form of estrogen in your body, which plays a crucial role in regulating your reproductive system, bone health, and overall hormonal balance. Many women use this test when they suspect hormonal imbalances are affecting their fertility, menstrual regularity, or overall well-being.

How should I prepare for this test?

No biotin: 72 hours

If you're taking high doses of biotin (vitamin B7 or B8, also called vitamin H or coenzyme R), you should stop taking it at least 72 hours before your blood draw, as it can interfere with test results. Otherwise, no special preparation is typically needed. Your doctor may request testing on a specific day of your menstrual cycle depending on what they're evaluating.

What's included in this test?

Estradiol

This test measures estradiol, the most active form of estrogen in your body, which directly impacts your menstrual cycle, fertility, mood, and bone health. Understanding your estradiol levels can help identify the causes of irregular periods, fertility challenges, unexpected weight changes, and symptoms of menopause or other hormonal imbalances.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your estradiol levels mean for your menstrual health, fertility, and hormonal balance. These notes include personalized recommendations like lifestyle changes, supplement suggestions, or whether you should consider hormone therapy or fertility treatments. You'll also get the standard lab report and can track your estradiol levels over time using our trends feature to see how your cycle changes or interventions are working.
Who should consider getting this test?
This test is important for women experiencing irregular or absent periods, difficulty conceiving, or unexplained fertility issues. It's also valuable for those going through menopause or perimenopause, women with symptoms of hormonal imbalance like mood swings or weight changes, and men experiencing symptoms of high estrogen like gynecomastia (breast enlargement), low libido, or erectile dysfunction.
What symptoms indicate I may need this test?
Common symptoms include irregular, missed, or very heavy periods, difficulty getting pregnant after trying for several months, unexplained weight gain or difficulty losing weight, and mood swings or depression. You might also experience hot flashes, night sweats, vaginal dryness, decreased sex drive, fatigue, or changes in breast tissue. In men, symptoms like breast enlargement, low energy, and sexual dysfunction may indicate high estrogen levels.
How can I naturally support healthy estrogen levels?
Maintaining a healthy weight through balanced nutrition and regular exercise helps regulate estrogen production. Include fiber-rich foods, cruciferous vegetables like broccoli and cauliflower, and flaxseeds which support healthy estrogen metabolism. Limiting alcohol consumption, managing stress through yoga or meditation, getting adequate sleep, and reducing exposure to environmental estrogens in plastics and personal care products can also help balance your hormones naturally.
What is estradiol and why does it matter?
Estradiol is the most potent and abundant form of estrogen in your body during your reproductive years. It regulates your menstrual cycle, supports fertility and pregnancy, maintains bone density, influences mood and energy levels, and affects metabolism and weight distribution. Both too much and too little estradiol can cause significant symptoms and health issues, which is why monitoring levels is important for overall health.
What does high estradiol mean?
High estradiol in women may result from ovarian tumors, certain medications, or conditions like polycystic ovary syndrome (PCOS). It can cause heavy or irregular periods, breast tenderness, mood swings, and weight gain. In men, elevated estradiol often comes from increased conversion of testosterone to estrogen, leading to gynecomastia, reduced libido, erectile dysfunction, and increased risk of prostate issues.
What does low estradiol mean?
Low estradiol in women can indicate menopause, premature ovarian failure, or problems with the pituitary gland that controls hormone production. Symptoms include absent or irregular periods, hot flashes, night sweats, vaginal dryness, decreased bone density, mood changes, and fertility problems. Low estradiol can significantly impact your ability to conceive and may require medical intervention depending on your age and reproductive goals.

What this means

Your estradiol levels are below the optimal range, which may explain symptoms like irregular periods, low energy, or difficulty with fertility. Low estradiol can affect your menstrual cycle, bone health, and overall hormonal balance, and may benefit from further evaluation.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
