D
Human chorionic gonadotropin is produced exclusively during pregnancy, which is why it is the basis for pregnancy tests. Estrogen, or estriol, levels increase throughout pregnancy, but the levels are not used to diagnose pregnancy because estrogen is present throughout childbearing years. Progesterone levels are not used to diagnose pregnancy, because they are present even if the woman is not pregnant. Luteinizing hormone levels are not used to diagnose pregnancy.
