What is the defined threshold for hyperbilirubinemia in newborns?

Hyperbilirubinemia in newborns is typically defined as a bilirubin level that exceeds 12 mg/dL. This condition is significant as it can lead to jaundice, which is common in newborns due to their immature liver function. Monitoring bilirubin levels is crucial in the early days of life to prevent potential complications, such as bilirubin encephalopathy, which can have serious long-term consequences.

The threshold of 12 mg/dL is based on clinical guidelines and recommendations from pediatric health organizations. Levels above this mark indicate a need for further assessment and possible treatment to manage the hyperbilirubinemia effectively. Understanding this threshold helps caregivers and health professionals ensure that newborns are screened appropriately for this condition.
