When total bilirubin levels exceed 40 μmol/L, bilirubin deposition at the sclera, skin, and mucous membranes will give these areas a yellow colour, thus it is called jaundice. [6] The increase in predominantly unconjugated bilirubin is due to overproduction, reduced hepatic uptake of the unconjugated bilirubin and reduced conjugation of bilirubin.
Blood test results are advised to always be interpreted using the reference range provided by the laboratory that performed the test. The SI units are μmol/L. [52] Typical ranges for adults are: [53] 0–0.3 mg/dl – Direct (conjugated) bilirubin level; 0.1–1.2 mg/dl – Total serum bilirubin level
Serum tests evaluate plasma bilirubin, haemolysis and liver function and are essential for definitive diagnosis. When total serum bilirubin exceeds 2.5 mg/dL and unconjugated bilirubin occupies >85% of total amount, it is classified as unconjugated hyperbilirubinemia. [6]
Blood test results should always be interpreted using the reference range provided by the laboratory that performed the test. [1] ... Total bilirubin: 1.7, [52] 2 ...
Jaundice in infants, as in adults, is characterized by increased bilirubin levels (infants: total serum bilirubin greater than 5 mg/dL). Normal physiological neonatal jaundice is due to immaturity of liver enzymes involved in bilirubin metabolism, immature gut microbiota, and increased breakdown of fetal hemoglobin (HbF). [ 54 ]
Results from the urine test should be confirmed by a complete blood count (CBC) and serum testing for total serum bilirubin and fractionated bilirubin. [32] Increased reticulocytes and the presence of schistocytes in the blood smear of the patient observed during CBC indicates hemolysis. [28]
