Figure 1 Gestational age impacts risk for severe hyperbilirubinemia. Finally, although Bf has biologic effects in the brain, the Bf level alone is not likely to dictate the risk for bilirubin encephalopathy.

Thereafter, the low—risk-zone threshold is less accurate because of the sampling bias that resulted in spuriously elevated levels in the lower zones more than the high-risk-zone 95th percentile in the study. Bilirubin-induced neurotoxicity depends on a complex interaction hyperbiilirubinemia the level and duration of CNS Bf exposure and the innate cellular characteristics of the developing CNS hyperbilirubinekia may predispose or protect against bilirubin-induced neuronal injury.
