Newborns are not usually told their blood type at birth, but may be told their blood type in cases such as neonatal pathologic jaundice and abnormal bleeding. If everything is normal after the birth of a newborn, the hospital will not test the blood type of the newborn, and will not inform the family what the blood type is. If the newborn has pathological jaundice, abnormal bleeding requiring blood transfusion, or if the family has a request, the hospital will draw blood from the umbilical cord, take blood from the end of the finger, or take blood from the heel to find out the baby’s blood type, and then the family will be informed of the blood type. After the birth of a newborn baby, we will check the baby’s bones, height, weight, hearing, thyroid function, screening for phenylketonuria, and generally will not specifically check the blood type. In addition, newborns who show abnormalities after birth need to seek medical treatment promptly.
