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. [2]

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).
Physical examination reviews clinical symptoms like degree of jaundice, vital signs and sensations of pain, further followed by urine tests, blood analysis and imaging. [3] [4] The degree of yellowish staining of the conjunctiva and skin in jaundice is proportional to hyperbilirubinemia to some extent. [6]
Mild jaundice may appear under conditions of exertion, stress, fasting, and infections, but the condition is otherwise usually asymptomatic. [7] [8] Severe cases are seen by yellowing of the skin tone and yellowing of the conjunctiva in the eye. [9] Gilbert syndrome has been reported to contribute to an accelerated onset of neonatal jaundice.
When the total serum bilirubin increases over 95th percentile for age during the first week of life for high risk babies, it is known as hyperbilirubinemia of the newborn (neonatal jaundice) and requires light therapy to reduce the amount of bilirubin in the blood. Pathological jaundice in newborns should be suspected when the serum bilirubin ...
For the first two days of life, healthy neonates have ratios of urinary coproporphyrin similar to those seen in patients with Dubin–Johnson syndrome; by 10 days of life, however, these levels convert to the normal adult ratio. [7] In post mortem autopsy, the liver will have a dark pink or black appearance due to pigment accumulation ...
Cholestasis is a condition where the flow of bile from the liver to the duodenum is impaired. [1] The two basic distinctions are: [1] obstructive type of cholestasis, where there is a mechanical blockage in the duct system that can occur from a gallstone or malignancy, and
