In the newborn liver, activity of glucuronyl transferase is only at 0.1-1% of adult levels, so conjugation of bilirubin is already reduced. Further inhibition of bilirubin conjugation leads to increased levels of bilirubin in the blood. [18] However, these results have not been supported by subsequent studies. [19]
Transient neonatal jaundice is one of the most common conditions occurring in newborns (children under 28 days of age) with more than 80 per cent experienceing jaundice during their first week of life. [53] Jaundice in infants, as in adults, is characterized by increased bilirubin levels (infants: total serum bilirubin greater than 5 mg/dL).
Neonatal cholestasis refers to elevated levels of conjugated bilirubin identified in newborn infants within the first few months of life. [1] Conjugated hyperbilirubinemia is clinically defined as >20% of total serum bilirubin or conjugated bilirubin concentration greater than 1.0 mg/dL regardless of total serum bilirubin concentration.

Bilirubin (BR) (from the Latin for "red bile") is a red-orange compound that occurs in the normal catabolic pathway that breaks down heme in vertebrates.This catabolism is a necessary process in the body's clearance of waste products that arise from the destruction of aged or abnormal red blood cells. [3]
Published series from Japan, North America, and the UK show that bilirubin levels will fall to normal values in about 50-55% of infants, allowing 40-50% to retain their own liver to reach the age of 5 and 10 years (and beyond).
In acute appendicitis, total bilirubin can rise from 20.52 μmol/L to 143 μmol/L. In pregnant women, the total bilirubin level is low in all three trimesters. [6] The measurement of bilirubin levels in the newborns is done through the use of bilimeter or transcutanoeus bilirubinometer instead of performing LFTs.

The presence of urobilinogen and its increased levels indicate that there are more than normal amounts of bilirubin in the intestine, showing that jaundice observed is not due to the blockage of bile flow, and is of pre-hepatic or hepatic causes. [32] Normal colour of the patient's urine indicates the absence of unconjugated bilirubin. [27]
