normal bilirubin values lie between reference ranges, the lower limit, and the upper limit. Direct bilirubin 0, 0.1, 0.2, and 0.3 is normal results and cannot be a cause of jaundice unless indirect bilirubin continue to be high. Indirect bilirubin 0.8, 0.7, 0.6, 0.5,0.4, and 0.3 are all normal levels of blood bilirubin. Normal bilirubin levels. Direct (conjugated) Bilirubin > or =12 months: 0.0-0.3 mg/dL (less than 5.1 µmol/L) Reference values have not been established for patients who are <12 months of age. Total Bilirubin. 0-6 days: Refer to www.bilitool.org for information on age-specific (postnatal hour of life) serum bilirubin values. 7-14 days: <15.0 mg/dL Elevated conjugated bilirubin should lead to increased total bilirubin. If the patient has normal conjugated bilirubin levels and elevated indirect bilirubin levels, it is a sign either of excessive hemolysis or of a failure of the liver as it struggles to cope with the normal rate of hemolysis. The level of direct, indirect and total bilirubin will be measured as part of a standard liver panel test. Conjugated bilirubin (direct bilirubin) —formed in the liver when sugars are attached (conjugated) to bilirubin. It enters the bile and passes from the liver to the small intestines and is eventually eliminated in the stool. Normally, no conjugated bilirubin is present in the blood. Figure 1. Unconjugated bilirubin and conjugated bilirubin metabolism Bilirubin tests are usually used to assess liver function and are presented as total, conjugated (direct), and unconjugated (indirect) bilirubin. Bilirubin reference or normal range is 0.2 – 1.2 mg/dL for total bilirubin (TBIL), and 0 – 0.3 mg/dL for direct or conjugated bilirubin (DBIL) [ 10 ]. Jaundice can occur in adults when bilirubin is higher than 2.3 mg/dL [ 37 ]. The UGT1A1 enzyme, which converts indirect bilirubin into direct bilirubin, is well-developed in the adult liver, but not in the livers of newborns. This is why jaundice with high indirect bilirubin is common in babies [ 2 ]. Bilirubin is a reddish yellow pigment made during the normal breakdown of red blood cells. Normal levels vary slightly from lab to lab; they range from about 0.2 – 1.2 mg/dL. Signs and symptoms of high bilirubin levels in adults vary with the underlying cause; however, symptoms usually include jaundice and itching. 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) What level of ALT is dangerous? A low level of ALT in the blood is expected and is normal. The approximate normal range of bilirubin in the blood serum is: 1.2 milligrams per deciliter (mg/dL) for adults 1 mg/dL for children under 18 years of age The skin normally becomes yellow once... 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. Total bilirubin levels are therefore indicative of both the destruction of red blood cells and the proper functioning of the liver, gallbladder, and bile ducts. Higher
