The newborn's jaundice level has already exceeded 275, indicating that the jaundice is elevated. Typically, when jaundice is high, it is advisable to complete liver function tests to check how high the bilirubin level is in the blood. If the bilirubin in the blood is also definitely above 275, this is certainly pathological jaundice. Pathological jaundice generally suggests going to the hospital, where a specialist in neonatology will guide the treatment based on the baby's specific condition. If the baby presents with other accompanying symptoms, hospital intervention and treatment might be necessary. If the general condition is still good, the doctor might advise you to go home with medication or other interventions, with regular follow-up appointments. It is recommended that parents seek timely hospital intervention for high jaundice levels.
