Normal value of estradiol

For women, the normal values of estradiol vary according to the physiological cycle: 1. Before puberty, the normal range is 18.35–110.10 pmol/L. 2. During the follicular phase, the normal range is 91.75–275.25 pmol/L. 3. During the luteal phase, estradiol levels remain high, with a normal range of 367–1101 pmol/L. 4. During the ovulatory phase, estradiol levels rise significantly, with a normal range of 734.0–2202.0 pmol/L. 5. During menopause, estradiol levels gradually decline, with a normal range of 18.35–91.75 pmol/L. Estradiol levels are influenced by multiple factors, and testing methods may vary between laboratories; therefore, the specific normal reference range should be interpreted according to clinical circumstances.
