The increase of the total bilirubin over 30-35 mmol/l results in bilirubin deposition in the tissues and yellow pigmentation of the skin, sclera and mucous membranes, called jaundice The fraction of the bilirubin, conjugated with glucuronic acid in the liver to form bilirubindiglucuronide is called conjugated bilirubin. Direct bilirubin or conjugated bilirubin: less than 0.3 mg/dL (less than 5.1 µmol/L) Total serum bilirubin: 0.1 to 1.2 mg/dL (1.71 to 20.5 µmol/L) Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different samples. Talk to your health care provider about the meaning of your specific test results. Total bilirubin = 0.3 to1.0 mg/dL or 5.1 to 17.0 mmol/L; Direct bilirubin = 0.1 to 0.3 mg/dL or 1.0 to 5.1 mmol/L; Indirect bilirubin (total bilirubin – direct bilirubin level) = 0.2–0.7 mg/dL; Raised level of direct bilirubin is seen in: Gallstones. Gallbladder tumors. Inflammatory scarring or obstruction of extrahepatic ducts. The bilirubin shown in urine and skin at serum bilirubin levels between 3.0 to 5.0 mg/dl, skin jaundice and eyes yellowish discoloration appear, urine color become dark yellow or as light tea when direct bilirubin is high in the blood, when indirect bilirubin is higher than 25mg/dl in the blood, it may show greenish plasma color as a result of sever elevation of indirect bilirubin (due to increased activity of biliverdin reductase enzyme which reduce biliverdin to bilirubin). Depending on the disorder unconjugated or conjugated bilirubin or both are major contributors to the resulting hyperbilirubinemia. Diseases or conditions which, through hemolytic processes, produce bilirubin faster than the liver can metabolize it, cause the levels of unconjugated (indirect) bilirubin to increase in the circulation. Liver immaturity and several other diseases in which the bilirubin conjugation mechanism is impaired cause similar elevations of circulating unconjugated ... The danger level for development of kernicterus is believed to be 320 µmol/L of unconjugated bilirubin. However, any result greater than 250 µmol/L should be regarded as a warning and the baby should be monitored carefully. The normal value for direct bilirubin or conjugated bilirubin is 0.1 - 0.3 mg/dL or 1.7-5.1 mmol/L. For indirect or unconjugated bilirubin, the normal values are 0.2-0.8 mg/dL or 3.4-12.0 mmol/L. Consult your medical practitioner to help understand your bilirubin tests. Bilirubin levels higher or lower than the normal values may not require immediate treatment unless it is persistent and reaches levels which are dangerously high. Adults. Total Bilirubin . mg/dL Normal (Reference Range) = 0.3 to 1.0 mg/dL; mmol/L Normal (Reference Range) = 5.1 to 17 mmol/L; Direct Bilirubin (Conjugated) In the liver, bilirubin is conjugated with glucuronic acid for solubilization and subsequent transport through the bile duct and elimination via the digestive tract. Diseases or conditions which, through hemolytic processes, produce bilirubin faster than the liver can metabolize it, cause the levels of unconjugated (indirect) bilirubin to increase in the circulation. Liver immaturity and several other diseases in which the bilirubin conjugation mechanism is impaired cause similar elevations ... A normal level is: Direct (also called conjugated) bilirubin: less than 0.3 mg/dL (less than 5.1 µmol/L) Total bilirubin: 0.1 to 1.2 mg/dL (1.71 to 20.5 µmol/L) Can bilirubin levels be lowered? Caffeine, penicillin, barbiturates, and nonsteroidal anti-inflammatory drugs (NSAIDs) called salicylates all lower bilirubin levels .
