Estradiol levels: what's normal, high and low
The primary form of estrogen. Levels vary widely with menstrual cycle, age, and reproductive stage.
Medically reviewed by Youmna DiStefano, MD · Last reviewed September 2026
The short answer
Estradiol is measured with a standard blood draw; no fasting is needed. A typical reference range is 10.0 – 40.0 pg/mL (male, age 18+; more bands below). At TestWell it's $35.99 all-in as Estradiol (E2), results in 1–3 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

Estradiol Reference Range
These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| Male, age 18+ | 10.0 – 40.0 pg/mL |
| Female, age 18+, varies by cycle phase | 15.0 – 350 pg/mL |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
