Could a simple hand soak reveal cystic fibrosis risk?

This study looks at whether soaking hands in water for up to 20 minutes can be a simple screening tool for cystic fibrosis (CF) carrier status. Researchers will take photos of participants' hands and score the wrinkling, both by human observation and using a computer algorithm. The study aims to enroll 2000 people who are interested in CF carrier research. Participants will only need one visit.
