What's this test for?

This test is ideal if you're experiencing irregular periods, unexplained mood swings, fertility issues, or symptoms that suggest hormonal imbalance. It measures all three forms of estrogen to help identify what's causing your hormonal symptoms and whether your estrogen levels are affecting your menstrual cycle, mood, or overall well-being. Many women use this test when they suspect hormone-related problems but want concrete answers.

How should I prepare for this test?

No biotin: 72 hours

You should stop taking any biotin supplements (also called vitamin B7, B8, vitamin H, or coenzyme R) at least 72 hours before your blood draw, as high-dose biotin can interfere with some tests in this panel. Otherwise, no special preparation like fasting is typically required. You can take this test at any point in your menstrual cycle, though your doctor may recommend specific timing depending on what they're evaluating.

What's included in this test?

Estrogen, Total Estriol, Serum Estradiol

This comprehensive panel evaluates all three forms of estrogen that play different roles in your body. Estradiol is the primary estrogen that regulates your menstrual cycle and affects mood, energy, and bone health. Estriol is particularly important during pregnancy, while estrone becomes more significant after menopause. Together, these measurements provide a complete picture of your hormonal balance and help identify the specific type of estrogen imbalance that may be causing your symptoms.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your estrogen levels mean for your menstrual cycle, mood, and overall hormonal health. These notes include personalized recommendations like lifestyle changes, supplement suggestions, or whether you should consider hormone therapy or further evaluation. You'll also get the standard lab report and can track your estrogen levels over time using our trends feature to see how your interventions are working.
Who should consider getting this test?
This test is ideal for women experiencing irregular or absent periods, unexplained fertility issues, or abnormal vaginal bleeding. It's also helpful for those going through perimenopause or menopause, women with severe mood swings or depression that may be hormone-related, and anyone wanting to understand their overall estrogen balance. If you're already on hormone therapy, this test can help monitor whether your treatment is working effectively.
What symptoms indicate I may need this test?
Common symptoms include irregular periods, very heavy or very light bleeding, difficulty getting pregnant, unexplained mood changes or depression, hot flashes or night sweats, and changes in libido. You might also experience vaginal dryness, bone loss concerns, persistent fatigue, or weight changes that don't respond to diet and exercise. If you're having multiple symptoms that seem hormone-related, this comprehensive estrogen panel can help identify the cause.
How can I naturally support healthy estrogen levels?
Maintain a healthy weight through balanced nutrition and regular exercise, as body fat can affect estrogen production. Include fiber-rich foods, cruciferous vegetables like broccoli and cauliflower, and flaxseeds which help with estrogen metabolism. Reduce alcohol consumption and manage stress through yoga, meditation, or adequate sleep. Limit exposure to endocrine disruptors found in plastics and certain personal care products.
What is estrogen and why does it matter?
Estrogen is the primary female sex hormone that regulates your menstrual cycle, supports bone health, affects mood and brain function, and influences your skin, hair, and metabolism. Your body produces three types: estradiol (most potent, active during reproductive years), estriol (dominant during pregnancy), and estrone (primary estrogen after menopause). Balanced estrogen levels are essential for reproductive health, emotional well-being, and long-term health of your bones and heart.
What does high estrogen mean?
High estrogen, also called estrogen dominance, can cause heavy or irregular periods, breast tenderness, bloating, mood swings, and weight gain especially around the hips and thighs. It may result from excess body fat, certain medications, stress, liver problems that affect hormone metabolism, or an imbalance with progesterone. Long-term elevated estrogen may increase risks for certain conditions, so it's important to identify and address the underlying cause.
What does low estrogen mean?
Low estrogen can cause irregular or absent periods, hot flashes, night sweats, vaginal dryness, mood changes, difficulty concentrating, and decreased bone density over time. This commonly occurs during menopause but can also result from excessive exercise, very low body weight, ovarian problems, or certain medical treatments. Low estrogen affects not just reproductive health but also bone strength, heart health, and cognitive function, making proper diagnosis and management important.

What this means

Your estradiol levels are below the optimal range, which may contribute to irregular periods, mood changes, low energy, or difficulty with fertility. Low estradiol is common during certain phases of your cycle, perimenopause, or due to factors like stress, excessive exercise, or very low body weight.

* 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.
