Measurement of the levels of bilirubin is used in the diagnosis and treatment of liver, hemolytic, hematologic, and metabolic disorders, including hepatitis and gallbladder obstructive disease.
Causes of high bilirubin: Liver disease: hepatitis, cholangitis, cirrhosis, other types of liver disease (including primary or secondary neoplasia); alcoholism (usually with high AST (SGOT), GGT, MCV, or some combination of these findings); biliary obstruction (intrahepatic or extrahepatic); infectious mononucleosis (look also for increased LD (LDH), lymphocytosis); Dubin-Johnson syndrome; Gilbert disease1 (familial hyperbilirubinemia) is encountered as a moderate elevation with otherwise unremarkable chemistries.
Anorexia or prolonged fasting: 36 hours or more may cause moderate rise.
Pernicious anemia, hemolytic anemias, erythroblastosis fetalis, other neonatal jaundice, hematoma, and following a blood transfusion, especially if several units are given in a short time.
Pulmonary embolism and/or infarct, congestive heart failure.
Significant deviations from the normal range may require further evaluation by your physician.
Bilirubin, Total
****Bilirubin, Total is included in the Comprehensive Metabolic Profile (CMP) and in the Liver Function Profile.***
No fasting required.
Estimated turnaround for results is 3 business days. If confirmation testing is required, the estimated time may be extended.
