Information about a laboratory test
Measures the blood level of estradiol, one of the main estrogens.
Measures the blood level of estradiol, one of the main estrogens.
Used to evaluate ovarian function, fertility, menstrual disorders, menopause, puberty, and some hormone treatments.
Low estradiol is expected after menopause; in reproductive-age people it can relate to ovarian or pituitary function, low body fat, or other causes.
High estradiol may be physiologic depending on cycle phase or pregnancy; medicines and ovarian or adrenal factors can also affect it.
Use the reference interval printed on your own laboratory report first. Hormone results may vary with the assay, age, sex, pregnancy, menstrual-cycle phase, and sampling time.
>= 10 – <= 50 pg/mL
Example reference interval
This is an example interval from the cited source. Menstrual-cycle phase, menopause, and pregnancy can materially affect reproductive-hormone results.
>= 30 – <= 400 pg/mL
Example reference interval
This is an example interval from the cited source. Menstrual-cycle phase, menopause, and pregnancy can materially affect reproductive-hormone results.
>= 0 – <= 30 pg/mL
Example reference interval
This is an example interval from the cited source. Menstrual-cycle phase, menopause, and pregnancy can materially affect reproductive-hormone results.
Reference ranges may vary by laboratory, method used, age, sex, pregnancy status, and clinical context. The reference range on your own laboratory report takes precedence.
Age, menopausal status, and cycle timing are critical for estradiol interpretation in females. One adult-female interval cannot represent all phases.
