Screen Positive Results

  • The chance that your baby has Down syndrome or trisomy 18 is HIGHER than the specific cut-off set by your centre..
  • A screen positive result does not mean that your baby has one of these conditions.
  • A screen positive result means you have the option to have genetic counselling and / or diagnostic testing (CVS, amniocentesis or ultrasound) to learn if your baby has one of the conditions.
  • Most screen positive results turn out to be false, either by diagnostic testing or the birth of a baby who does not have Down syndrome or trisomy 18.  This is called a false positive.
