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.
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.
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 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.
Recommended actions
Maintain a healthy body weight through balanced nutrition, as being underweight can lower estrogen
Include healthy fats from avocados, nuts, seeds, and fatty fish to support hormone production
Manage stress levels with relaxation techniques like yoga or meditation
Consider retesting in 6-8 weeks, ideally on day 3 of your menstrual cycle if applicable
