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.
Bilirubin (formerly referred to as haematoidin) is the yellow breakdown product of normal heme catabolism, caused by the body's clearance of aged red blood cells which contain hemoglobin.Bilirubin is excreted in bile and urine, and elevated levels may indicate certain diseases.yperbilirubinemia results from a higher-than-normal level of bilirubin in the blood. For adults, this is any level above 170 Î¼mol/l and for newborns 340 Âµmol/l and critical hyperbilirubinemia 425 Âµmol/l. Mild rises in bilirubin may be caused by: 1  Hemolysis or increased breakdown of red blood cells.
