Neonatal jaundice points out the normal value of general serum bilirubin about 225 μmol/L, and then the newborn 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 serum bilirubin is also within the normal range of values, 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, you must go to the hospital for relevant tests to find the cause of jaundice, which can generally be treated with light therapy, chemotherapy, liver-protective therapy, herbal medicine, etc.
