measurement of each of these variables by kinetic studies with radiolabeled bilirubin permits a precise classification of cases of unconjugated hyperbilirubinemia into those due to increased bilirubin turnover ( for example , hemolysis ) , those due to decreased bilirubin clearance ( for example , gilbert 's syndrome ) , and those in which both mechanisms operate .
