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 that is bound to a certain protein is called unconjugated, or indirect, bilirubin. Conjugated, or direct, bilirubin travels freely through your bloodstream to your liver. Most of this bilirubin passes into the small intestine, but a very small amount passes into your kidneys and is excreted in your urine.This bilirubin also gives urine its distinctive yellow color.onjugated, or direct, bilirubin travels freely through your bloodstream to your liver.
