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 Only conjugated bilirubin (=water soluble) 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 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. The liver cells that form the conjugated bilirubin excrete it into the bile, where it is then excreted into the intestinal tract through the bile duct. Bilirubin in the urine indicates the presence of hepatocellular disease or intra- or extra-hepatic biliary obstruction. Urine bilirubin is negative (0 to 0.2 mg/dL (0 to 0.34 µmol/L). Bilirubin can be detected in urine by the Foam test. Procedure for the foam test: Place a small volume of the urine in the test tube, cap it, and shake it vigorously. Result: Foam at the top is white means bilirubin is negative. If the foam is orange color means bilirubin is present. Other methods to detect the bilirubin in the urine are: Diazo reaction in the form of tablets or Dipstick. Fouchet’s test. Ferric chloride test. 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. The bilirubin level is checked during urinalysis. The presence of bilirubin in urine is medically known as bilirubinuria. The presence of bilirubin in urine is usually associated with liver and gallbladder disease. A bilirubin in urine normal range does not possess any health risk but once grows out of control can be extremely fatal. Bilirubin is not normally present in the urine. 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. A bilirubin in urine test is only one measure of liver function. If your results are abnormal, your health care provider may order additional blood and urine tests, including a liver panel. A liver panel is a series of blood tests that measure various enzymes, proteins, and substances in the liver. It is often used to detect liver disease.
