What is the normal level of jaundice in children?

Medical research shows that the highest normal value of jaundice in children is about 51.3μmol/L, basically 4 days after birth: premature infants: neonatal jaundice, neonatal jaundice refers to the abnormal metabolism of bilirubin in the neonatal period, the increase of bilirubin level in the blood, characterized by yellowing of the skin, mucous membranes, and sclera, which is the most common clinical problem in newborns. This disease can be divided into physiological and pathological.

Generally speaking, physiological jaundice refers to temporary jaundice caused by the metabolic characteristics of bilirubin. It appears 2 to 3 days after birth, reaches a peak on the 4th to 6th day, and disappears on the 7th to 10th day. It lasts longer in premature infants and has no other clinical symptoms except mild loss of appetite. If jaundice occurs within 24 hours after birth, serum bilirubin increases by more than 5 mg/dl per day or >0.5 mg/dl per hour; it lasts for a long time, >2 weeks for full-term infants and >4 weeks for premature infants, and it still does not disappear, or even continues to deepen and worsen or reappears after disappearing, or jaundice begins to appear within one to several weeks after birth, it is pathological jaundice.

Often have the following characteristics:

① Early onset, within 24 hours after birth;

② Severe: 12.9 mg/dl for full-term infants and 15 mg/dl for premature infants;

③ Rapid progression, with serum bilirubin rising by more than 5 mg/dl per day;

④ Lasts for a long time, or recurs.
