Hyperbilirubinemia

Evaluation of hyperbilirubinemia:
feeding history (squash, carrots, sweet potatoes can all make eyes yellow/orange), blood type, Direct Coombs, CBC, retic count, Total and Direct bilirubinemia, head to toe progression, transcutaneous bilirubin meter, yellow gums.

No reported cases of kernicterus in healthy term infants.
Nevertheless, ALWAYS order a bilirubin for newborns. There is no reason kernicterus should happen. It is completely preventable.

Jaundice Risk Factors without Hemolysis:
Jaundice in first 24 Hours
Previous Jaundice in a sibling
Gestational 35-38 weeks (That's 38, even though limit of prematurity is 37 weeks.)
Exclusively breastfed
East Asian race
Easy Bruising
Maternal Age > 25 years old
Male Sex

Always check the level because scleral icterus is not 100%.

Possible causes of hyperbilirubinemia:
Loss of blood
Increased shunt
Overproduction
Hemolysis
Polycythemia
Increased Enterohepatic Circulation
Bowel Obstruction
Intestinal Hypomotility
Undersecretion
-decreased conjugation
liver disease
