Regional Treatment Centres

Babies who screen positive for one or more of the diseases tested are referred by Newborn Screening Ontario (NSO) to specialized follow-up centres called Regional Treatment Centres. If you are trying to locate a specific Regional Treatment Centre, please visit our Find a Follow-Up Centre page.

As a health care provider working at one of these centres, you are responsible for:

  • Confirmatory testing of babies who screen positive
  • Treatment and management of true positive cases
  • Providing follow-up outcome information to NSO
  • Education of local health care providers
