title: The need for quality improvement in sweat testing infants after newborn screening for cystic fibrosis.
abstract: The proportion of insufficient sweat tests after positive newborn screening for cystic fibrosis was determined. Infants ≤ 3 months old had a mean (± standard deviation) rate of 7.2% (± 7.6) (range, 0% to 40%). Collection methods did not affect the rates. The high and variable rates indicate a need for quality improvement.
