What is a normal serum bilirubin value for a newborn needs to be determined based on a combination of gestational age and day of life.
After birth, the serum bilirubin value is different at different stages.
According to the epidemiological survey of normal neonatal jaundice in China, the average serum bilirubin value of full-term healthy newborns is 77.29 μmol/L on the first day of birth, 123.29 μmol/L on the second day, 160.91 μmol/L on the third day, 183.82 μmol/L on the fourth day, and 195.28 μmol/L on the fifth day.
However, the mean value is not equal to the standard value, and exceeding this range is not necessarily abnormal. It also needs to be evaluated by referring to the standard curve of phototherapy at hour of postnatal age for neonates of different gestational ages and different risk factors according to whether they are preterm or not, and whether they have risk factors.
In conclusion, if a newborn develops jaundice, he/she should go to the hospital in time to identify the type and cause of jaundice and then cooperate with the doctor for treatment.
