In order to prevent disability or death, the Board shall require every hospital in the Commonwealth having a newborn nursery to perform a critical congenital heart defect screening test using pulse oximetry or other Board-approved screening test that is based on standards set forth by the American Academy of Pediatrics on every newborn in its care when such infant is at least 24 hours old but no more than 48 hours old or, in cases in which the infant is discharged from the hospital prior to reaching 24 hours of age, prior to discharging the infant. Any infant whose parent or guardian objects thereto on the grounds that such tests conflict with his religious practices or tenets shall not be required to receive such screening tests. The physician or health care provider in charge of the infant’s care after delivery shall cause such tests to be performed.
