Cystic fibrosis (CF) is one of the most complex disorders faced by pediatricians and continues to be not only a challenge but an enigma for both physicians and researchers. Although there is no cure for the pulmonary disease associated with CF, a variety of clinical observations1-3 strongly suggest that early recognition and aggressive treatment can have a beneficial effect on the course of the disease. Thus, there has been considerable interest in the possibility of routine neonatal diagnosis by screening.
