However, conjugated bilirubin is water-soluble and may be eliminated from the body through the urine if it cannot pass into the bile. Measurable bilirubin in the urine usually indicates blockage of liver or bile ducts, hepatitis, or some other form of liver damage and may be detectable early in disease; for this reason, bilirubin testing is integrated into common dipstick testing used for routine urinalysis. Bilirubin is primarily derived from metabolism of hemoglobin. Only conjugated bilirubin is excreted into the urine and normally only trace amounts can be detected in urine. Elevated urinary bilirubin occurs in patients with obstructive jaundice or jaundice due to hepatocellular disease or injury. However, urine bilirubin is relatively insensitive for detection of liver disease. Hyperbilirubinemia due to hemolysis is principally due to unconjugated bilirubin, and therefore does not result in ... The conjugated bilirubin is present in bile, while the unconjugated bilirubin is not present in bile. The conjugated bilirubin is normally not present in urine, but appears in high plasma concentrations. The unconjugated bilirubin is not present in urine. The conjugated bilirubin is not toxic to the tissues. The unconjugated bilirubin is toxic to the tissues. The accumulation of unconjugated bilirubin in the brain leads to kernicterus (neurologic damage). [Purification of conjugated bilirubin from human urine]. [Article in Chinese] Guo Y(1), Chen M, Tu Y, Luo H, Li S, Yan D, Niu M. Author information: (1)School of Basic Medical Sciences, WCUMS, Chengdu 610041, China. OBJECTIVES: To develop a simple, practical method with fine yield and purity for separating conjugated bilirubin(Bc) from a sustainable and facile material in order that it could ... If the conjugated bilirubin levels are higher than the unconjugated bilirubin, this is typically due to a malfunction of the liver cells in conjugating the bilirubin. This is commonly seen with drug reactions, hepatitis, as well as any type of liver disease. This can also been seen due to some sort of blockage of the bile ducts. Causes include gall stones, tumors, or scarring of the bile ducts. The conjugated Bilirubin passes through the urine. If this is not the case, Bilirubin flows in your body through the red blood cells. Since Bilirubin comes out as a part of the bile, a color is imparted to the urine and feces as well. There is a further break down in the small intestine, turning into Urobilinogen and circulating in the bloodstream. Understanding of Bilirubin in urine causes, symptoms and treatments is mandatory. Conjugated bilirubin is formed by the breakdown of hemoglobin in the red blood cells. The liver converts this bilirubin into direct bilirubin, which can then be released into the intestine by the gallbladder for elimination. Nursing Tip: Conjugated bilirubin is water soluble. If there is some sort of blockage of the bile ducts, excess conjugated bilirubin can be removed from the body through urine. This is why bilirubin is tested for in the standard urinalysis.blockage of the bile ducts. To learn more, view our Advanced Bladder Management course. Conjugated or direct hyperbilirubinaemia occurs when the the liver is able to conjugate bilirubin, but the excretion is impaired. Causes include: failure of bilirubin excretion by hepatocytes: Dubin-Johnson syndrome; Rotor's syndrome; obstruction to biliary flow i.e. cholestasis, both intra-hepatic and extra-hepatic What causes bilirubin in urine? A bilirubin is usually conjugated in the liver and will then become water soluble. The bilirubin found in the urine is the unconjugated type. It is not soluble in the water, which means that the kidney cannot filter it. Bilirubin in the urine is indicative of the presence of conjugated hyperbilirubinemia. (5)
