"High bilirubin" refers to a condition where the level of bilirubin in the blood is elevated. Bilirubin is a yellow pigment produced by the breakdown of red blood cells. It is normally processed by the liver, but high levels can indicate a problem with the liver or an excessive breakdown of red blood cells. This can result in yellowing of the skin (jaundice) and may be a sign of various liver or blood disorders.
