In babies with clinical jaundice, nurses will measure the jaundice value daily and compare the values to observe the changes in the baby’s jaundice to determine the severity of the development of the baby’s jaundice and the effectiveness of the treatment. The normal value of neonatal jaundice is based on serum bilirubin as a reference indicator, as long as the value of serum bilirubin does not exceed 12.9 mg/dl in full-term babies and 15 mg/dl in preterm babies, it is generally normal, but it should also be noted that if the jaundice value is >6 mg/dl on the first day after birth and >9 mg/dl on the second day, it is also abnormal. The hourly graphs of jaundice are used for comparison. In general, physiologic jaundice usually resolves in less than 2 weeks in term infants and in less than 4 weeks in preterm infants, but if the jaundice is delayed or recedes and reappears, it is also pathologic jaundice. A daily rise in total serum bilirubin of 5 mg/dl is generally diagnosed as pathological jaundice. Physiologic jaundice generally appears 2 days after birth with an increase in serum bilirubin values, peaking in 3-5 days and naturally subsiding in 7-10 days. This is a jaundice value generally does not exceed 15 mg/dl, which is within the normal range. Jaundice values for birth infants are important for detecting changes in the development of jaundice in infants and for the treatment of doctors. Parents are advised to actively cooperate with the doctor to test the values correctly and timely to avoid damage to the baby’s nervous system from bilirubin.
