Screen Positive Follow-Up
The image below walks you through the process that happens when a baby's blood spot sample has a screen positive result. For more information about what happens when a baby is screen positive for Critical Congenital Heart Disease (CCHD) please view the Screen Positive Results page.

Screen Positive Result
Disease ruled out (false positive)
No further follow-up is needed.
- If diagnostic testing rules out the disease for which a baby screened positive, the newborn screening result is considered a false positive result. In other words, false positive results are when a baby screens positive for a disease, but follow-up testing shows that the baby does not actually have the disease.
- False positive results cause unnecessary worry for families but come as a by-product of striving to find every baby who has the disease. Sometimes false positive newborn screening results can be explained, but most often there is no explanation.
The Regional Treatment Centre continues to follow the baby and more testing may be needed.
Disease confirmed (true positive)
The specialist physician and team provide follow-up treatment and care for the disease.
- If a baby is diagnosed with the disease for which he/she screened positive; the newborn screening result is considered a true positive result and healthcare providers at the Regional Treatment Centre will discuss treatment and management options with his/her parents.
- There is wide variation in the clinical presentation of the diseases that the newborn screen detects. Therefore, some babies who have had diagnostic testing indicating that they have a disease will remain healthy or have only very mild symptoms, even without treatment.
