How is multiple pregnancy diagnosed?
Many women think they are pregnant with more than 1 baby. The healthcare provider may diagnose multiple babies 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 baby 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 probe (transducer), especially in early pregnancy. Or they can be done with an abdominal probe in later pregnancy.
