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 is a yellow pigment that is in everyoneâs blood and stool. If you notice a yellowing of your skin or the whites of your eyes, this is called jaundice, and it may be caused by high levels of bilirubin. Bilirubin is made in the body when old red blood cells are broken down.The breakdown of old cells is a normal, healthy process.After circulating in your blood, bilirubin then travels to your liver. In the liver, bilirubin is excreted into the bile duct and stored in your gall bladder.esting for bilirubin in the blood is therefore a good test of damage to your liver. Newborn infants often have some jaundice, and bilirubin in the blood may be tested several times in the first few days of an infantâs life to check that the liver is starting to work properly.
