Raised unconjugated hyperbilirubinemia is seen in:
Gilbe's Syndrome
Dubin Johnson syndrome
Drug induced cholestasis
Hepatocellular necrosis
Gilbe's syndrome- mild unconjugated hyperbilirubinemia, normal values for standard hepatic biochemical tests and normal hepatic histology other than a modest increase of lipofuscin pigment in some patients. Serum bilirubin concentrations are most often < 3 mg/dL. Extra edge : Crigler-Najjar syndrome I is often lethal, although Crigler-Najjar syndrome II is compatible with life and often presents with extreme jaundice and neurologic defects secondary to kernicterus. Both DubinJohnson syndrome and Rotor syndrome cause conjugated hyperbilirubinemia
