blood test, total bilirubin, unconjugated bilirubin, indirect bilirubin, conjugated bilirubin, direct bilirubin, bilirubin, breakdown product of hemoglobin, total, direct bilirubin, measured to screen, to monitor liver, gall bladder dysfunction, blood is drawn, a vein, venipuncture, capillary, laboratory centrifuges the blood to separate the serum, cells, bilirubin test, on the serum, fast, at least 4 hours, instruct to discontinue drugs that affect the test, drugs, increase bilirubin measurements include allopurinol, anabolic steroids, antibiotics, antimalarials, azathioprine, chlorpropamide, cholinergics, codeine, diuretics, epinephrine, meperidine, methotrexate, methyldopa, mao inhibitors, morphine, nicotinic acid, oral contraceptives, phenothiazines, quinidine, rifampin, salicylates, steroids, sulfonamides, theophylline, drugs, decrease bilirubin measurements include barbiturates, caffeine, penicillin, high-dose salicylates, this test is useful in determining, a patient has liver disease, a blocked bile duct, bilirubin metabolism begins, the breakdown of red blood cells, red blood cells contain hemoglobin, is broken down to heme, globin, heme is converted to bilirubin, is then, carried by albumin, in the blood, liver, liver, the bilirubin is chemically attached to a glucuronide, it is excreted, in the bile, "conjugated" bilirubin, direct bilirubin, unconjugated bilirubin, indirect bilirubin, total serum bilirubin equals direct bilirubin plus indirect bilirubin, conjugated bilirubin is excreted, bile by the liver, stored, in the gall bladder, transferred, small intestines, bilirubin is further broken down by bacteria, in the intestines to urobilins, contribute, color, the feces, a small percentage of these compounds, reabsorbed, eventually appear, in the urine, where they, urobilinogen, direct bilirubin, 0 to 0.3 mg/dl, total bilirubin, 0.3 to 1.9 mg/dl, mg/dl = milligrams per deciliter, normal values, from laboratory to laboratory, jaundice, discoloration of skin, sclera, the eye, occurs, bilirubin accumulates, in the blood at a level greater than approximately 2.5 mg/dl, jaundice occurs, red blood cells, broken down too fast, the liver to process, in the liver, bile duct blockage, bile ducts, obstructed, direct bilirubin, build up, escape, liver, end up, in the blood, levels, high enough, of it, appear, in the urine, direct bilirubin appears, in the urine, increased direct bilirubin, that the biliary, liver secretion, ducts, obstructed, increased indirect, total bilirubin, erythroblastosis fetalis, gilbert's disease, hemolytic anemia, hemolytic disease, the newborn, physiological jaundice, normal in newborns, sickle cell anemia, transfusion reaction, pernicious anemia, resolution of a large hematoma, increased direct bilirubin, bile duct obstruction, cirrhosis, crigler-najjar syndrome, dubin-johnson syndrome, hepatitis, additional conditions under which the test performed, biliary stricture, cholangiocarcinoma, cholangitis, choledocholithiasis, hemolytic anemia, due to g6pd deficiency, hepatic encephalopathy, idiopathic aplastic anemia, idiopathic autoimmune hemolytic anemia, immune hemolytic anemia, secondary aplastic anemia, drug-induced immune hemolytic anemia, thrombotic thrombocytopenic purpura, wilson's disease interfering factors, hemolysis of blood, falsely increase bilirubin levels, lipids, in the blood, falsely decrease bilirubin levels, bilirubin is light-sensitive, decomposes in light.
