Although prenatal screening for hemoglobinopathies is not obligatory during pregnancy in Italy, it is offered to women by the Italian National Health Service in the pre-conception phase. The screening of newborns is a valid alternative, and has been adopted in various European countries, albeit in a piecemeal fashion. Neonatal screening has the advantage of providing early diagnosis of a hemoglobinopathy. Here we report the findings from the experience with neonatal screening in Friuli-Venezia Giulia since 2010.</p><p><strong>Materials and methods: </strong>The hemoglobinopathy screening project in Friuli-Venezia Giulia, a Region in north Italy, began in November 2010.

Increased mobility and migratory flows bringing in hemoglobinopathy carriers from endemic areas have led to an increase in mutations in non-malarial countries, with a current incidence of around 4% in the newborns we tested.
