Estradiol (E2)
What does Estradiol (E2) measure?
The Estradiol (E2) test measures the level of estradiol, a form of estrogen hormone, in the body. It may be used to evaluate ovarian function, menstrual irregularities, fertility concerns, menopause-related changes, or hormone therapy monitoring. In males and children, it may also help assess certain hormone-related conditions or puberty concerns. Results are interpreted alongside symptoms, medical history, and other hormone test results.
