Neonatal jaundice is one of the common symptoms during the newborn period; it can be a normal physiological phenomenon or an external manifestation of certain diseases. Generally, about 80% of full-term infants can be visibly seen having yellow-tinted skin. There is a normal range for monitoring jaundice. For full-term infants, this should not exceed 6 within the first 24 hours after birth, not exceed 9 within 48 hours, not exceed 12 within 72 hours, and not exceed 15 after 72 hours. If these values are exceeded, it is advisable to visit a hospital, where a pediatrician can conduct relevant examinations based on the infant’s specific condition. If pathological jaundice is diagnosed, timely intervention and treatment are necessary.
