What Does a Estradiol Test Measure?
Estradiol (E2) is the most potent and prevalent form of estrogen in premenopausal women. This test measures its concentration in your blood. Estradiol plays critical roles in reproductive function, bone density, cardiovascular health, and brain function. Levels fluctuate significantly throughout the menstrual cycle, making timing of the test important.
How the Test Works
The Estradiol test is performed via a standard blood draw at any Quest Diagnostics location. Your sample is sent to a CLIA-certified lab for analysis. Results are typically available within 1-2 business days in your JustLabs account.
