Estradiol
Estradiol levels are used in evaluating ovarian function. Estradiol levels are increased in cases of early (precocious) puberty in girls and gynecomastia in men. Its main use has been in the differential diagnosis of amenorrhea – for example, to determine whether the cause is menopause, pregnancy, or a medical problem. In assisted reproductive technology (ART), serial measurements are used to monitor follicle development in the ovary in the days prior to in vitro fertilization. Estradiol is also sometimes used to monitor menopausal hormone replacement therapy.
Preparation: No special preparation is needed. Fasting is not required for this blood test. In general, being well hydrated (drinking plenty of water before the blood draw) will help make your veins somewhat easier to locate and access for the blood draw.
