Prenatal ultrasound testing at MedStar Health

Your obstetrician will discuss each test with you so you understand what the test is screening for and any possible risks.

Our PDUC offers:

  • Ultrasound: A non-invasive imaging test that uses sound waves to create a picture of the fetus. The images help the doctor assess the baby’s growth and development
  • First trimester combined screening combines two tests:

    • Nuchal translucency ultrasound screening, also called the NT, which helps your physician determine your baby’s risk of having Down’s syndrome, certain chromosomal abnormalities, or major congenital heart problems
    • Blood sample analysis measures certain proteins that are produced by the placenta. If the fetus has Down’s syndrome, the protein levels may be elevated
  • Chorionic villus sampling (CVS) and amniocentesis: These are more invasive prenatal diagnostic tests that can detect chromosomal abnormalities, such as Down’s syndrome and other genetic disorders
  • Electronic fetal heart monitoring: Used to assess the fetus’ heart rate
  • Genetic counseling is an option: Even before contemplating a pregnancy, genetic counseling can help you understand your risks and options; also appropriate if a screening test has diagnosed an abnormality in the fetus
