is hyperbilirubinemia common in newborns.
yes. in the newborn, an imbalance between bilirubin production and bilirubin metabolism or clearance from the body results in an excess of circulating bilirubin and thus jaundice is common. bilirubin is one of the breakdown products of hemoglobin that results from red blood cell destruction.when rbc's are destroyed,the breakdown products are releaded into the circulation, where the hemoglobin splits into two fractions:heme and globin. the globin portionis used by the body,and the heme portion is converted to unconjugated bilirubin,an insoluble substance bound to albumin.
