Estradiol
Primary estrogen. Interpret against cycle timing or menopausal status. Lower results are the ones to watch. A common adult reference interval is 10–400 pg/mL.
Typical adult range
- Reference interval
- 10–400 pg/mL
- Often-cited tighter window
- 30–200 pg/mL
Cycle-phase dependent — interpret with timing. Your own lab's printed range is the one that applies to your result.
What commonly moves it
