hi my 5th day baby's bilirubin test report is 13 can u plz suggest me shall I give phototherapy for my baby r need to check for 7th day test

A. A commonly used rule of thumb in the NICU is to start phototherapy when the total serum bilirubin level is greater than 5 times the birth weight. Thus, in a 1-kg infant, phototherapy is started at a bilirubin level of 5 mg/dL; in a 2-kg infant, phototherapy is started at a bilirubin level of 10mg/dL and so on.
