Estradiol (E2) is a blood test that measures the level of estradiol, the main form of estrogen in the body.
Why is the test done?
It may be ordered to:
Evaluate menstrual irregularities or fertility problems
Assess ovarian function
Monitor ovulation or fertility treatment
Investigate symptoms of menopause
Evaluate early or delayed puberty
Monitor hormone therapy
Investigate abnormal estrogen levels in men, such as gynecomastia
What does the test involve?
A small blood sample is taken, usually from a vein in your arm. Fasting is generally not required, unless your doctor has ordered other tests that require fasting.
Estradiol levels
The normal range varies considerably depending on:
Sex
Age
Menstrual-cycle phase
Pregnancy
Menopause
Medications/hormone therapy
The laboratory's testing method
Therefore, an E2 result should be interpreted using the reference range printed on your laboratory report, rather than a single universal “normal” value.
If you have your E2 result (with units and the lab's reference range), paste it here and I can explain what it generally means.
