Long QT syndrome is not one of the conditions included on newborn screening tests. The purpose of newborn screening programs are to identify newborns at risk of a potentially fatal or disabling condition as early as possible, ideally prior to any signs or symptoms. The goal is to diagnose early and treat as soon as possible to mitigate effects of the condition. Long QT syndrome presents in adolescence and/or adulthood, there is no need to include this on any newborn screening tests. Furthermore, it is not an easy or straightforward diagnosis to make. Therefore, unless there is a personal or family history of long QT syndrome, individuals are not routinely screened for long QT syndrome.
