A newborn tested with a serum bilirubin level of 437 on the 6th day after birth, after treatment with blue light therapy and human albumin, the bilirubin level dropped to 297. Parents are worried that this condition may affect the baby’s brain, especially considering that the hospital has not yet identified the cause of the hyperbilirubinemia. The baby is in good spirits and eating well, and the MRI did not reveal any abnormalities. Will this treatment process and the undetermined cause have a long-term impact on the baby’s brain function?
