Skin-interfaced Colorimetric Bifluidic Sweat Sensor Device for the Diagnosis of Cystic Fibrosis (CF)

Cystic fibrosis (CF) is a multisystem autosomal recessive inherited disease affecting approximately 75,000 individuals in USA. The sweat chloride (Cl) test remains the gold standard for diagnosis of CF but still has a number of limitations. The objectives of this study are: 1)To evaluate a skin-interfaced colorimetric bifluidic sweat device with two synchronous channels as a potential low-cost but potentially accurate test to diagnoses cystic fibrosis (CF) and 2) To evaluate measurements of sweat chloride (Cl) using this same system in comparison to the standard clinical laboratory procedures routinely performed in the Clinical Laboratory at Penn State Health Milton S. Hershey Medical Center (PSH-HMC), Hershey, PA for assessment of the diagnosis of CF. This is a single institution study performed solely at PSH-HMC. Study participants will include 1) adults 18 years of age or older capabl
