In addition to dried-blood spot screening tests, the Newborn Screening Program provides education for Critical Congenital Heart Disease (CCHD) pulse oximetry screening.
It is recommended that newborns be tested for CCHD after 24 hours of life, but before discharge from the hospital. Pulse oximetry is a non-invasive and painless test to measure oxygen saturation in the blood and can help detect some congenital heart defects in babies who have no other signs or symptoms.
