Evidence of Hemolysis
Onset of jaundice within 24 h, presence of pallor and hydrops, presence of hepatosplenomegaly, presence of hemolysis on the smear of peripheral blood, increased count of reticulocyte (>8%), rapid rise of bilirubin (>5 mg/dl in 24 h or >0.5 mg/dl/hr) or a family history of considerable jaundice should create a suspicion of hemolytic jaundice
