Aquagenic Wrinkling Prediction

The goal of this observational study is to determine whether an aquagenic wrinkling procedure (i.e., soaking hands in a water bath for up to 20 minutes) can be used as a screening tool for cystic fibrosis carrier status. Participants will complete one visit where they will undergo an aquagenic wrinkling procedure to see how their hands respond.
