Unconjugated hyperbilirubinemia with increased urobilinogen in -

In all uncomplicated hemolytic anemias,the excess serum bilirubin is unconjugated.The level of hyperbilirubinemia depends on functional capacity of liver & the rate of hemolysis. When liver is normal jaundice is rarely severe . Excessive bilirubin excreted by liver into GIT leads to increased formation and fecal excretion of urobilin ie increased urobilinogen Ref : Robbin 9/e pg 632
