Differentiation between physiologic jaundice, which is seen in many infants during the first week of life, and pathologic jaundice is essential because pathologic jaundice is a sign of a more neonatal jaundice, jaundice, bilirubin serious condition. Jaundice Physiologic jaundice is characterized by unconjugated hyperbilirubinemia that peaks by the third or fourth day of life in full-term newborns and then steadily declines by 1 week of age.
Asian newborns tend to have higher peak bilirubin concentrations and more prolonged jaundice.
Premature infants are more likely to develop jaundice than jondice Causes of Physiologic Jaundice Increased bilirubin load due to the high red blood cell volume in newborns and shortened blood cell survival Deficient hepatic uptake and deficient conjugation of bilirubin Increased enterohepatic bilirubin reabsorption Deficient excretion of bilirubin. Conjugated hyperbilirubinemia never has a physiologic neonatal jaundice, jondice jaundice, bilirubin cause and must always be investigated.
