Newborn screening is a public health program of screening in infants shortly after birth for a list of conditions that are treatable, but not clinically evident in the newborn period. Some of the conditions included in newborn screening programs are only detectable after irreversible damage has been done; in some cases sudden death is the first manifestation of a disease. Screening programs are often run by state or national governing bodies with the goal of screening all infants born in the jurisdiction.
