New wearable stickers simplify cystic fibrosis diagnosis
A pair of wearable stickers may transform diagnostic sweat testing for cystic fibrosis (CF), a genetic disorder that causes problems with digestion and breathing.
A pair of wearable stickers may revolutionize cystic fibrosis (CF) diagnosis by simplifying the sweat chloride test. A study published in npj Digital Medicine revealed the stickers to be reliable and accurate, offering a less expensive, simpler, and more accessible alternative to standard laboratory testing. The new "CF SWIFT" device, developed by Northwestern University's Querrey Simpson Institute for Bioelectronics, features a soft stimulator and smartphone app to analyze sweat chloride content.
With the potential to increase access to diagnostic testing, especially in rural and lower-income areas, early diagnosis could significantly improve life expectancy from under five years without treatment to over 66 years with treatment. Further validation in a multicenter study involving younger infants and regulatory approval are required before clinical use.
