    Area of Science:

    • Medical Research
    • Pediatrics
    • Genetics

    Background:

    • Cystic fibrosis (CF) is a genetic disorder requiring early detection.
    • Newborn screening programs are crucial for identifying infants with CF.
    • The Crossley test is a common method for newborn screening.

    Purpose of the Study:

    • To determine the incidence of cystic fibrosis in New Zealand newborns.
    • To evaluate the effectiveness of the Crossley test in a national screening program.

    Main Methods:

    • A 12-month screening of all New Zealand newborns using the Crossley test.
    • Follow-up testing for infants with elevated blood immunoreactive trypsin levels.
    • Clinical and laboratory studies for definitive diagnosis.

    Main Results:

    • 49,056 newborns were screened.
    • 522 infants had elevated immunoreactive trypsin levels.
    • 14 confirmed cases of cystic fibrosis were diagnosed, yielding an incidence of 1:3500.

    Conclusions:

    • The study established the incidence of cystic fibrosis in New Zealand.
    • Newborn screening effectively identifies potential CF cases for early intervention.
