This study is being done to learn more about sweat electrolytes in people who do not have Cystic Fibrosis to inform goals for CF treatment.
This study will involve a one-time visit with sweat testing. If you do not know if you carry a cystic fibrosis gene mutation, it may involve a blood draw for genetic testing. You will receive $30 in compensation for your time.
You may be eligible if you do NOT have a diagnosis of cystic fibrosis, you are over the age of 12, and you know whether or not you carry CF gene mutations (or are willing to have limited genetic testing done)
