Why It Is Done
A test for estrogen is done to:
- Help detect fetal birth defects (especially Reference Down syndrome Opens New Window) during pregnancy. When the test for estriol is combined with alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCG), it is called a triple screen test. When the amount of a hormone called inhibin A is also measured along with estriol, AFP, and hCG, the test is called a quad marker screen. Other blood tests and fetal ultrasound may be done as well.
- Evaluate estrogen-producing tumors of the ovaries in girls before menstruation starts and in women after menopause.
- Explain abnormal sexual characteristics in men, such as enlarged breasts (gynecomastia). This test can also help detect the presence of estrogen-producing tumors growing in the testicles.
- Monitor therapy with fertility medicines.
