Perinatal Diagnostics Center

Perinatal Diagnostics Center

The El Camino Hospital/Stanford Children's Health Perinatal Diagnostic Center, located on our Mountain View campus, offers prenatal testing and consultation services for women during pregnancy.

Our specialized team of maternal-fetal medicine specialists (high-risk obstetricians), sonographers (ultrasound technologists) and genetic counselors offer a wide range of services and support for women during pregnancy — including counseling and consultations for high-risk pregnancies.

We believe the very best care meets both your medical and emotional needs, so our experts provide you with the information and support you need to make the choices that are right for you.

Genetic Counseling

Genetic counselors interpret your family and medical history to determine the chance of genetic disease occurring. Your counselor will help you and your family members understand inheritance, testing, management and prevention. He or she will also provide you with the educational resources and information you need to make informed choices.

Your doctor might refer you to a genetic counselor if you have:

  • Abnormal prenatal screenings, DNA tests or ultrasound results.
  • A family history of physical abnormality or a known chromosomal, metabolic or genetic disorder.
  • Previous miscarriages.
  • A union between relatives (consanguinity).
  • Exposure to substances that may cause fetal defects (teratogens), including certain drugs or medications, infections, alcohol, toxins and chemotherapy.

During your appointment, your counselor will recommend testing options based on your family history, ethnicity and previous pregnancies — including screenings for chromosomal disorders or particular family traits that concern you.

Prenatal Testing

We provide a range of tests to screen for and diagnose chromosomal abnormalities and assess the health of your baby, including:

  • Amniocentesis. During this test, a sample of your amniotic fluid is taken to test for some chromosomal and genetic disorders, including Down syndrome and spina bifida.
  • Chorionic villus sampling (CVS). CVS tests for chromosomal and genetic problems by testing a sample of your placental tissue.
  • Nuchal translucency (NT). This screening test helps determine whether your baby is likely to have a chromosomal disorder such as Down syndrome, trisomy 13, trisomy 18 or a congenital heart defect.
  • Ultrasound. Also called sonograms, noninvasive ultrasound exams use high-frequency sound waves to create an image of your baby. Ultrasound is used to verify your due date and evaluate your baby's anatomy and growth. Doppler blood flow, a type of ultrasound exam, can evaluate blood flow through the baby's umbilical cord and assess placental functioning or blood flow abnormalities.
  • Cell-free DNA screening. This test assesses your baby’s risk for having a genetic disorder such as Down syndrome.

We offer additional testing, such as fetal echocardiography to assess your baby's heart and procedures such as percutaneous umbilical cord blood sampling or intrauterine blood transfusion to diagnose and treat hemolytic disease. Our professionals can provide a full range of screening and diagnostic procedures.
