Your baby’s first test

Between 24 and 48 hours after birth, your baby’s nurse will do a series of screening tests. These screens include a heel prick, where blood is taken from your baby’s heel, a hearing screen, and in some states, a heart screen often referred to as “pulse-ox.”

These screenings are designed to pick up a range of different health issues before they lead to long term complications or even death. When found early, babies with these different conditions can receive early treatment and can lead normal lives.
