 The most common signs of jaundice in adults are a yellowish discoloration of the white area of the eye (sclera) and skin with scleral icterus presence indicating a serum bilirubin of at least 3 mg/dL.Other common signs include dark urine (bilirubinuria) and pale, fatty stool (steatorrhea).Because bilirubin is a skin irritant, jaundice is commonly associated with severe itchiness.
