    most doctors

Screening vs Diagnostic Testing
  • Screening tests identify the risks of your baby
    being born with a birth defect
  • Normally offered during first or second trimester

  • Diagnostic tests are performed when a screening
    test detects a potential problem
  • More invasive than screening tests
