WebIn general, unconjugated hyperbilirubinemia is a result of accelerated hemolysis, impaired unconjugated bilirubin uptake by the liver, and decreased bilirubin conjugation, whereas conjugated hyperbilirubinemia is due to impaired conjugated bilirubin excretion.[2] Normal total bilirubin levels in blood are less than 17 µmol L−1in adults. WebMar 1, 2007 · It is apparent in infants when the serum bilirubin value is greater than 4 to 5 mg/dL (68.4 to 85.5 mcmol/L) and in older children at values greater than 2 to 3 mg/dL (34.2 to 51.3 mmol/L).
