The Estriol (E3) test measures the level of estriol, a form of estrogen that is most prominent during pregnancy. Estriol is produced primarily by the placenta and reflects fetal and placental well-being during pregnancy.
This test is commonly used in prenatal screening as part of maternal serum testing to help assess pregnancy health and fetal development. Outside of pregnancy, estriol levels are typically low and may be measured in specific hormonal or metabolic evaluations.
