Newborn jaundice value on the fourth day is high, is it necessary to be hospitalized for blue light

If the jaundice value is greater than 15mg/dl on the fourth day after birth, it belongs to severe jaundice and needs to be admitted to hospital for blue light irradiation treatment. If it is diagnosed as hemolytic jaundice, severe cases also need to be treated with exchange transfusion combined with blue light irradiation. Usually, give the baby hot water and sun exposure to promote jaundice in the body.
