Experiencing irregular periods, hot flashes, mood swings, changes in libido, or fertility issues? The Estradiol (E2) Test can provide insights into your hormonal balance. This medical assessment measures estradiol levels in the blood-an important estrogen hormone produced by the ovaries. It’s used to evaluate reproductive health, monitor hormonal therapies, and diagnose conditions like PCOS or menopause-related concerns. Understanding estradiol levels can offer essential information for managing symptoms and optimizing reproductive well-being.
