A jaundice value of 8.5mg/dL is normal for a 20-day-old newborn.
In full-term newborns, the normal value of jaundice is usually no more than 12mg/dL, and the normal value of jaundice in preterm infants is less than 15mg/dL, so a jaundice value of 8.5mg/dL in a 20-day-old newborn is normal.
For newborns, jaundice is normally seen on the 3rd to 4th day after birth and peaks in a week or so, but it also depends on the time of measurement. Normal neonatal jaundice usually subsides within 14 days, and in preterm newborns it subsides within 28 days.
After the birth of a newborn baby, we should advocate breastfeeding, and at the same time about 9 o’clock in the morning sun, pay attention to sun protection, and pay attention to warmth, absolutely must prevent cold and cold, strengthen the child care, and go to the hospital for regular checkups to assess the development of newborn babies.
