Screen Positive Follow-Up

When a baby's blood sample is screen positive for SMA, the health care providers at Newborn Screening Ontario (NSO) refer the baby to specialized follow-up clinics in their region for more testing. NSO refers to these specialized centres as newborn screening Regional Treatment Centres.  The centres include:

  • London Health Sciences Centres, London
  • Hamilton Health Sciences Centre, Hamilton
  • Hospital for Sick Children, Toronto
  • Kingston General Hospital, Kingston
  • Children’s Hospital of Eastern Ontario, Ottawa

Typically babies are referred to their closest centre.  For families that live in more remote locations, they can decide which of the five centres they would prefer to attend.

Health care providers at the Regional Treatment Centres then contact the baby’s doctor, midwife, nurse practitioner, or parents directly to inform them of the results and arrange appointments and tests that are required.  Due to how newborn screening is performed for SMA the likelihood is very high that the baby will be confirmed to have SMA.  At the baby’s first appointment the specialists will likely discuss treatment and management options.
