Specimen must be protected from light and transported to the laboratory promptly. Theyll insert a hollow needle and draw out a small sample into a vial. The yellow tint of the skin and eyes reflects the buildup of bilirubin in the body's tissues. Here it undergoes further breakdown, becoming brown as the iron in the hemoglobin oxidizes. It is first converted to biliverdin and then to unconjugated bilirubin within macrophages in the reticular endothelial system.5 Unconjugated bilirubin is lipid soluble and passes easily through cell membranes to bind to albumin in serum, whereas free (unbound) bilirubin is taken up by liver hepatocytes and converted to conjugated bilirubin.4,6 Conjugated bilirubin is water soluble and is transported from liver hepatocytes into the biliary tract system where it passes to the intestines and is excreted into the stool.

Crigler-Najjar syndrome is a more severe variant of the same enzyme deficiency.13 Patients with impaired conjugation due to low levels of the bilirubin-UGT enzyme are particularly susceptible to jaundice from medications that inhibit this enzyme, such as protease inhibitors.6 Table 1 lists the causes of unconjugated hyperbilirubinemia.5,7,912, The largest worldwide contributor to liver disease is viral hepatitis, mostly from hepatitis C.14 Viral hepatitis causes increased oxidative stress within hepatocytes, leading to cell death, scarring, and diminished liver mass available for normal function.4,15 Chronic alcohol consumption can cause various hepatic disorders, including steatosis or fatty liver disease with minimal symptoms and often no jaundice; alcoholic hepatitis with acute onset jaundice and more severe symptoms; and cirrhosis, which is often associated with decompensation and liver failure in the setting of jaundice.3 Jaundice in persons with alcoholic liver disease can occur via multiple mechanisms, such as direct hepatocellular damage caused by ethanol metabolites or from alcohol's effect on bile acid uptake and secretion contributing to cholestasis.3,16, Approximately 30% to 40% of patients with nonalcoholic fatty liver disease progress to nonalcoholic steatohepatitis, and approximately 40% to 50% of these patients develop fibrosis or cirrhosis that may lead to hyperbilirubinemia.17 Although the exact mechanism is poorly understood, liver lipid deposition may trigger inflammation and fibrosis, particularly when coupled with type 2 diabetes.17 Sepsis may also induce hyperbilirubinemia as circulating acute phase reactants and bacterial endotoxins disrupt bilirubin transport, leading to cholestasis and elevated bile salt levels.18,19, Drug-induced liver injury has multiple potential mechanisms, including direct hepatocellular toxicity and activation of an immune response that advances the inflammatory cascade, inhibiting bilirubin transport into canaliculi, which causes cholestasis.20 Wilson disease, a rare genetic disorder, is associated with a loss of function of a cellular transporter responsible for moving dietary copper into liver canaliculi. Jaundice occurs when the serum bilirubin level exceeds 3 mg per dL (51.3 mol per L). The process of destroying hemoglobin takes place in the liver, where it is first converted to bilirubin (a yellow pigment). It can also give levels of two different types of bilirubin: unconjugated and conjugated. All Rights Reserved.

Doctors use the age of the newborn and the bilirubin type and levels to determine if treatment is necessary.

When your liver processes the bilirubin, it unbinds it from the albumin and binds it to a sugar molecule, making it water-soluble. [rev 11/09], 2023 MLABS A Division of Pathology, Michigan Medicine.

If the jaundice etiology is unknown after the initial laboratory evaluation, it is necessary to perform additional tests including hepatitis panels and autoimmune panels, such as antinuclear, smooth muscle, and liver-kidney microsomal antibodies.3, Noninvasive imaging modalities in persons with jaundice include ultrasonography, computed tomography, and magnetic resonance cholangiopancreatography. Direct bilirubin correlates with conjugated bilirubin but tends to overestimate actual conjugated bilirubin, as it includes both the conjugated bilirubin and bilirubin covalently bound to albumin (delta-bilirubin). African-Americans tend to have lower bilirubin levels than people of other races. Imaging with ultrasonography or computed tomography can differentiate between extrahepatic obstructive and intrahepatic parenchymal disorders.
