Estradiol Level Reference Chart
Typical reference ranges for Estradiol (E2) across different demographics and menstrual cycle phases. Note: Ranges vary by laboratory and assay method.
| Demographic / Phase | pmol/L (SI Unit) | pg/mL (Conventional) |
|---|---|---|
| Adult Male | 40 – 160 | 11 – 44 |
| Early Follicular Phase | 70 – 500 | 19 – 136 |
| Mid-Cycle Peak (Ovulation) | 400 – 1500 | 109 – 408 |
| Luteal Phase | 200 – 800 | 54 – 218 |
| Postmenopausal | < 100 | < 27 |
Estradiol Conversion FAQ
Everything you need to know about converting Estradiol blood test units and understanding your results.
To convert Estradiol from picomoles per litre (pmol/L) to picograms per millilitre (pg/mL), divide the pmol/L value by 3.671. For example, 100 pmol/L divided by 3.671 equals approximately 27.24 pg/mL.
Normal Estradiol (E2) levels vary significantly. For adult males, it is typically 11-44 pg/mL. For premenopausal females, it ranges from 19-408 pg/mL depending on the menstrual cycle phase. Postmenopausal levels are usually under 27 pg/mL. Always consult your doctor for interpretation.
pmol/L is the standard SI (International System) unit used in the UK, Australia, Canada, and many European countries. pg/mL is the conventional unit predominantly used in the United States. Both measure the exact same hormone, just using different molecular weight calculations.
The conversion factor of 3.671 is derived from the molecular weight of Estradiol (E2), which is approximately 272.38 g/mol. The precise formula is: pg/mL = pmol/L ÷ 3.671.
