What is the Estradiol Test?
The estradiol test measures estradiol (E2), the main and most active form of oestrogen. It shows how well the ovaries are working and is used to look at periods, fertility treatment, menopause and, in men, causes of hormone imbalance.
Estradiol Test normal range
| Measurement | Typical adult value |
|---|---|
| Women, early follicular phase | about 12–166 pg/mL |
| Women, mid-cycle peak | about 85–498 pg/mL |
| Women, luteal phase | about 43–211 pg/mL |
| Women, after menopause | usually below about 30 pg/mL |
| Men | about 10–40 pg/mL |
Estradiol swings widely through the menstrual cycle, so the day of the cycle matters, and results differ between assays. Pregnancy, birth control pills and hormone therapy all change it. The range on your own report governs.
Ranges differ between laboratories and methods. The reference range printed on your own report is the one to read your result against.
What your Estradiol Test result means
- Low (before menopause)
- Can occur with low body weight, heavy exercise, premature ovarian insufficiency, or pituitary or hypothalamic problems. It is read with FSH, LH and AMH.
- Low (after menopause)
- Expected. Levels fall as the ovaries stop making oestrogen.
- High (women)
- Can be normal near ovulation or during fertility treatment. Persistently high levels are less common and may need tests for an ovarian cause.
- High (men)
- Can be seen with obesity, liver disease or some medicines, and rarely with a hormone-producing tumour.
One result is not a diagnosis. A doctor reads it with your symptoms, history, medicines and other tests.
Why is the Estradiol Test done?

Estradiol Test: sample & preparation
- You do not need to fast for this test. If you are still menstruating, tell the lab which day of your cycle you are on, as the result is interpreted against cycle day.
