Elevated total serum bilirubin levels should be fractionated to direct and indirect bilirubin fractions and an elevated serum conjugated bilirubin implies hepatocellular disease or biliary obstruction in most settings. A liver biopsy may be considered when serologic testing and

Bilirubin •The height of the total Bb is seldom of value in specifying the cause of the jaundice. •However: –In common bile duct obstruction it is unusual to be >15 mg/dl. It is usually 25-30 mg/dl, extrahepatic cholestasis is unlikely. –Uncomplicated hemolysis and Gilbert´s seldom cause values >6 mg/dl.

ism. After cessation of breastfeeding, the serum bilirubin concen-tration began to decrease in all cases. When breastfeeding was resumed, serum bilirubin concentration again became elevated in some infants, but the concentration fell to within normal range (8.55–12.2 mmol/L), or jaundice disappeared visually for all in-fants by 4 months of age.

Excess conjugated bilirubin in serum may be excreted by kidneys (dark urine). Albumin-bound unconjugated bilirubin cannot be excreted by kidneys. With longstanding elevated serum conjugated bilirubin, less is in urine because of covalent binding to albumin. Causes of Hyperbilirubinemia and Jaundice

study the bilirubin concentration was found to be higher in patients with non-severe Covid-19 (mean difference −0.25 μmol/L).3 The pooled results revealed that bilirubin concentration was signifi-cantly higher in patients with severe Covid-19 (SMD: 0.48 μ mol/L; 95% CI, 0.11 to 0.85mol/L, Pμ= .012). The heterogeneity was

Please note that bilirubin should be >30umol/L for measurement of conjugated bilirubin to be valid. Therefore please do not request conjugated bilirubin testing in patients whose total bilirubin is below this level. If diagnostic uncertainty remains then genetic analysis for Gilberts is available. However it is expensive and usually unnecessary.

The production of un-conjugated bilirubin may exceed the conjugating capacity of the liver and hence the serum levels of indirect (and of total) bilirubin will be raised and that of direct in the upper normal range or just a little elevated. • The other liver function tests will usually give normal results
