JAUNDICE
A yellow discoloration of the skin due to an elevated bilirubin level.
The normal level of bilirubin in the blood is 1 mg/dL. If the concentration increases to 2 mg/dL, yellowing of the skin, sclera, and mucous membranes will become evident. Yellowing due to increased levels of bilirubin in the blood (hyperbilirubinemia), which then deposits in the tissues of the body, is called jaundice or icterus. Depending on the site of the problem, hyperbilirubinemia is usually dominated by either the unconjugated or conjugated type.
