J Pediatr. 2010 Dec;157(6):1035-7. doi: 10.1016/j.jpeds.2010.07.053. Epub 2010 Sep 16.


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.
