When your baby is 1 to 2 days old, he has some special tests called newborn screening. Newborn screening checks a baby for serious but rare and mostly treatable health conditions at birth. It includes blood, hearing and heart screening.
Your baby can be born with a health condition but may not show any signs of the problem at first. If a health condition is found early with newborn screening, it often can be treated. Early treatment is important, because it may help prevent more serious health problems for your baby.
