Normally, the physiologic jaundice value of a newborn is below 10mg/dL. However, as whether the newborn is premature or whether the newborn has other high prevalence factors, such as whether there is hypoxia at birth as well as asphyxia, etc., these are some of the factors in determining the value of physiologic jaundice in newborns. However, overall, if the jaundice level of a newborn is below 10mg/dL, most of them are physiologic jaundice, because the incidence of physiologic jaundice is still particularly high in Chinese people. Most newborns have a very low level of physiologic jaundice value, but the newborn’s mental state and milk intake are not affected, so the determination of the physiologic jaundice value of the newborn should not only be combined with the specific jaundice index, but also the general condition of the newborn. If the newborn’s mental state is good, the milk intake is fine, and the newborn does not appear to be screaming or trying to sleep all the time, this situation is generally not a big problem, and parents do not need to be particularly worried.
