The normal value of neonatal jaundice is generally serum bilirubin does not exceed about 225 μmol/L. Again, neonatal physiological jaundice and pathological jaundice must be distinguished from each other. Physiological jaundice generally appears within 7-14 days of birth, the skin and sclera are normal, and the serum bilirubin is within the normal range, physiological jaundice does not have any clinical symptoms and takes time to recover slowly, so physiological jaundice is nothing to worry about. Pathological jaundice must be noted that jaundice appears within 24 hours of birth, the skin and sclera are aggravated, and the serum bilirubin exceeds normal values. Therefore, when pathological jaundice occurs, it is important to go to the hospital for relevant examinations to find the cause of jaundice, which can generally be treated with light therapy and medication.
