Cross-species summary: Bilirubin is an orange bile pigment produced by the breakdown of haem and reduction of biliverdinin. An excess of bilirubin in the blood, resulting from a defect in uptake of organic anions by the liver, is called hyperbilirubinaemia I or Gilbert's syndrome. Another anion unable to be taken up by affected livers is phylloerythrin, a metabolite of chlorophyll. The resultant high blood levels of phylloerythrin result in photosensitive dermatitis.
