Summary

A 55-person study found strong agreement between a color-changing wearable test and standard cystic-fibrosis measurements.

Northwestern and Lurie Children's researchers tested a two-sticker system that collects sweat, changes color with chloride concentration and is read by a smartphone in under an hour. Among 55 participants, including 52 with cystic fibrosis or related conditions, results closely tracked standard testing. The small study needs multicenter validation in younger infants and regulatory review before clinical adoption.
