Parent Information on Newborn Screening

Here’s what parents should know about the Newborn Screening Program:
 
Every baby born in Connecticut receives a newborn screening bloodspot test within 24–48 hours after birth. A few drops of blood are collected from the baby’s heel and sent to the Connecticut State Public Health Laboratory. These tests help detect rare but treatable conditions early—before symptoms appear. 
 
Why is Newborn Screening Important?
 
Babies with certain disorders may appear healthy at birth but can develop:
 
  • Slow brain development
  • Feeding difficulties
  • Poor weight gain
  • Severe illness
  • Risk of death
Early detection and treatment through newborn screening can prevent serious health problems and save lives.

What Does an "Out-of-Range or Abnormal" Result Mean?

A screen positive, out-of-range, or abnormal result does not mean your baby has a disorder. It means further evaluation is needed.
 
Possible causes of an out-of-range or abnormal result:

  • If you took certain medications while pregnant
  • If your baby was born early
  • If your baby’s blood was collected too soon
  • If your baby had certain treatments while in the hospital
  • For many other reasons
