What to watch with Östradiol and menopause?

When it comes to estradiol and menopause, the key is clinical assessment, not genetic testing. Estradiol is the primary estrogen and declines sharply during menopause. A blood test for estradiol can help determine menopausal status, especially with irregular cycles. However, levels fluctuate widely, so a single measurement is often not conclusive. Genetic tests for estradiol-related genes (e.g., CYP1A1, COMT) have no clinical utility in menopause – they do not predict current hormone levels or individual risk for hot flashes. Evidence for such DNA tests is weak (mechanistic, non-replicated). Important: discuss symptoms and quality of life with a doctor; consider hormone replacement therapy (HRT) if indicated. Beware of direct-to-consumer tests claiming to optimize HRT timing – they are not evidence-based.
