How is multiple pregnancy diagnosed?
Many women suspect they are pregnant with more than 1 baby. The healthcare provider
may diagnose multiple fetuses early in pregnancy. This is especially true if fertility
treatments were used. The provider may make the diagnosis with a health history, physical
exam, and the following tests:
Pregnancy blood testing. Levels of human chorionic gonadotropin (hCG) may be quite high with multiple pregnancy.
Alpha-fetoprotein. Levels of a protein released by the fetal liver and found in the mother's blood may
be high when more than 1 fetus is making the protein.
Ultrasound. This is an imaging test that uses high-frequency sound waves to create images of blood
vessels, tissues, and organs. Ultrasounds can be done with a vaginal transducer, especially
in early pregnancy. Or they can be done with an abdominal transducer in later pregnancy.
