Bilirubin is a degradation product of hemoglobin. Increased levels occur in hemolysis, liver damage or occlusion of bile ducts.
|Neonates||24h||< 8.8 mg/dL||< 150 µmol/L|

|3rd day||0.7 - 12.7 mg/dL||12 - 217 µmol/L|
|4th-6th day||0.1 - 12.6 mg/dL||1.7 - 216 µmol/L|
|Children||>1 month||0.2 - 1.0 mg/dL||3.4 - 17 µmol/L|
|Adults||0.1 - 1.2 mg/dL||1.7 - 21 µmol/L|
Each laboratory should check if the reference ranges are transferable to its own patient population and determine own reference ranges if necessary. For diagnostic purposes, the results should always be assessed with the patient’s medical history, clinical examinations and other findings.
