Estradiol: units, conversion and tracking
Updated
Short answer
Estradiol is reported in pg/mL, pmol/L and ng/dL. 1 pmol/L = 0.2724 pg/mL.

What is estradiol?
The main form of oestrogen, made mostly by the ovaries and in smaller amounts in other tissues, including in men.
BiomarkerHQ groups estradiol under Hormones. On lab reports it can also appear as oestradiol, e2, estradiol e2, 17-beta estradiol, estradiol sensitive and estradiol ultrasensitive.
Estradiol units and conversion
BiomarkerHQ stores each estradiol result in the unit printed on the report, and charts and compares results in pg/mL.
1 pmol/L = 0.2724 pg/mL
1 pg/mL = 3.671 pmol/L
1 ng/dL = 10 pg/mL
1 pg/mL = 0.1 ng/dL
| pmol/L | pg/mL |
|---|---|
| 50 pmol/L | 13.62 pg/mL |
| 100 pmol/L | 27.24 pg/mL |
| 150 pmol/L | 40.86 pg/mL |
| 200 pmol/L | 54.48 pg/mL |
| 300 pmol/L | 81.71 pg/mL |
| 400 pmol/L | 109 pg/mL |
| 500 pmol/L | 136.2 pg/mL |
| pg/mL | pmol/L |
|---|---|
| 10 pg/mL | 36.71 pmol/L |
| 20 pg/mL | 73.43 pmol/L |
| 30 pg/mL | 110.1 pmol/L |
| 50 pg/mL | 183.6 pmol/L |
| 75 pg/mL | 275.4 pmol/L |
| 100 pg/mL | 367.1 pmol/L |
| 150 pg/mL | 550.7 pmol/L |
For another value, use the lab unit converter. It converts units only and does not interpret a result.
Tracking estradiol over time
In BiomarkerHQ, each estradiol result is saved with its collection date, its unit and the reference range printed on that report. The timeline charts the results across your draws against the range from each of your own reports, and any two draws can be compared side by side.
- Keep the unit printed on each report. Convert only to compare.
- Keep each report's own range with its result. See why ranges differ between labs.
- Compare the same lab and conditions where you can. See how to compare two blood tests.
Frequently asked questions
Which units do labs report estradiol in?
Estradiol is reported in pg/mL, pmol/L and ng/dL. BiomarkerHQ stores each result in the unit printed on the report and uses pg/mL for charts and comparisons.
How do I convert estradiol from pmol/L to pg/mL?
1 pmol/L = 0.2724 pg/mL. For example, 200 pmol/L is 54.48 pg/mL.
How do I convert estradiol from pg/mL to pmol/L?
1 pg/mL = 3.671 pmol/L. For example, 50 pg/mL is 183.6 pmol/L.
Does BiomarkerHQ interpret my estradiol result?
No. It compares a result only with the reference range printed on your own lab report, as below, within or above, and does not say what the result means. Talk to a qualified clinician about your results.
