<P> Cystic fibrosis ( CF ) was first added to newborn screening programs in New Zealand and regions of Australia in 1981 , by measuring immunoreactive trypsinogen ( IRT ) in dried blood spots . After the CFTR gene was identified , Australia introduced a two tier testing program to reduce the number of false positives . Samples with an elevated IRT value were then analyzed with molecular methods to identify the presence of disease causing mutations before being reported back to parents and health care providers . CF is included in the core panel of conditions recommended for inclusion in all 50 states , Texas was the last state to implement their screening program for CF in 2010 . Alberta was the first Canadian province to implement CF screening in 2007 . Quebec , New Brunswick , Nova Scotia , Newfoundland and Prince Edward Island do not include CF in their screening programs . The United Kingdom as well as many European Union countries screen for CF as well . Switzerland is one of the latest countries to add CF to their newborn screening menu , doing so in January 2011 . </P>
