This is an observational comparative study to compare the standard-of-care methods for sweat testing used to support diagnosing cystic fibrosis (CF) against a new method of sweat testing called the CF Quantum Sweat Test System. The results of the new device in this study are for comparison ONLY and will NOT be used to diagnose, treat or mitigate the subject's condition.

The primary aim of the study is to determine if the CF Quantum Sweat Test provides sweat chloride results that are equivalent to the results from traditional sweat testing. The secondary aim of the study is to assess the quantity not sufficient rate of the CF Quantum Sweat Test compared to traditional sweat testing.
