ESTRADIOL REFERENCE RANGES
Males: <20-53 pg/mL
Females:
Males: <20-53 pg/mL
Females:
- Postmenopausal females (untreated) <20-48 pg/mL
- Non-pregnant females
- Mid-follicular phase(-6 to -8 days from hLH peak) 23-139 pg/mL
- Mid-luteal phase(+6 to +8 days from hLH peak) 42-338 pg/mL
- Peri-ovulatory phase(day -1 from the hLH peak) 83-495 pg/mL
Clinical Significance
Levels of estradiol are used to monitor ovulatory status. Because estradiol levels reflect follicular maturation, the measurement of estradiol as cited in the scientific literature has been used as a tool in the assessment of sexual development, etiology of amenorrhea, causes of infertility and menopause. Abnormally high levels in males are indicative of feminizing syndromes such as gynecomastia.
