The goal of this research study was to collect blood, urine, and sputum samples to be stored for future research. This is called specimen banking. Information about the amount of salt in sweat, and information about health such as lung function, weight and questionnaires was also collected. Researchers for future cystic fibrosis research may use the banked specimens and the health information to develop tests that could be used to help identify additional drugs that can help people with CF. At specific study sites people participated in sub-studies that involved additional procedures such as sweat rate testing, ability to clear mucus from the lungs, induced sputum collection, or taking a gastrointestinal pH pill.
