Bilirubin is primarily a product of the breakdown of red blood cells by the liver. Elevated bilirubin in urine causes include a malfunction of the liver-resulting in the kidneys performing the filtration responsibilities and therefore causing the bilirubin to be removed through the urine.
A bilirubin test is used to detect an increased level in the blood. It may be used to help determine the cause of jaundice and/or help diagnose conditions such as liver disease, hemolytic anemia, and blockage of the bile ducts.Bilirubin is an orange-yellow pigment, a waste product primarily produced by the normal breakdown of heme.f conjugated (direct) bilirubin is elevated more than unconjugated (indirect) bilirubin, there typically is a problem associated with decreased elimination of bilirubin by the liver cells.
