Jaundice index is serum bilirubin. Serum bilirubin 17mg/dL is considered high for a 2-day-old child, and it is considered to be caused by pathologic jaundice.
Jaundice is a common phenomenon in early neonatal period, the normal serum bilirubin of full-term newborns should be less than 12.9mg/dL, 17mg/dl is out of the range, so this value is higher, considering pathological jaundice, such as hemolysis, infection, biliary obstruction and so on. It needs to be treated accordingly.
Serum bilirubin 17mg/dL in a child born just 2 days ago, if accompanied by abnormal manifestations, or jaundice persists, etc., should be promptly diagnosed and treated under the guidance of a doctor.
