Who Is Referred to a Perinatal Diagnostic Center?

Our Perinatal Diagnostic Centers (PDCs) provide a wide range of prenatal testing, consultation and genetic counseling services. Some of the reasons a pregnant woman may be referred to a PDC include:

• Level 2 ultrasound
• Growth scan to check your baby’s growth
• Nonstress testing
• Prenatal testing for chromosomal and neural tube defects
• Biophysical profile - ultrasound imaging of amniotic fluid volume and fetal movement, breathing and tone
• Meeting with a genetic counselor to discuss:
  • Prenatal genetic screening and diagnostic testing options
  • Genetic issues associated with advanced maternal age
  • A positive result from the State of California Prenatal Screening Program
  • Family history of physical abnormality or a known chromosomal, metabolic or genetic condition
  • Multiple miscarriages
  • Marriage between relatives (consanguinity)
  • Problems diagnosed by ultrasound
  • Testing for a specific genetic disorder
  • Exposure to teratogens (substances which may cause fetal defects). These include some drugs or medications, infections, alcohol, toxins and chemotherapy.
