Bаby Emily, а 3-dаy-оld infant, is brоught tо the pediatrician by her parents due to persistent constipation and abdominal distension since birth. Physical examination reveals a distended abdomen and a rectal examination indicates the absence of stool in the rectal vault. An abdominal X-ray confirms the presence of a significant amount of stool in the dilated bowel loops. The pediatrician suspects Hirschbrung's disease and refers the infant to GI for further testing. What testing would confirm this diagnosis?
