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.
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.
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 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.
Recommended actions
Ensure adequate calorie and healthy fat intake to support hormone production
Reduce excessive exercise if applicable and prioritize rest and recovery
Manage stress through mindfulness, yoga, or adequate sleep (7-9 hours)
Consider retesting in 4-6 weeks, ideally mid-cycle for more accurate assessment
