Novel Point-of-care Sweat Chloride Testing Device for Monitoring CFTR Function
This study is being done to test a device called micro Sweat Test Patch (mSTP or µSTP).
The study team will compare the standard of care (SOC) method of sweat testing with a novel sweat test technique using an integrated micro Sweat Test Patch (µSTP) with microneedle assembly made out of Pilocarpine nitrate, microfluidic channels, and a chloride sensor for point-of-care (POC) measurements of sweat chloride concentrations in newborns being evaluated for cystic fibrosis (CF) diagnosis and in pediatric and adult people with CF (pwCF).
The procedures involve performing a SOC sweat test (if they are not a neonate) and the novel sweat test developed by the research team.
Recruitment for the study will take place at Children's Healthcare of Atlanta and Emory Healthcare cystic fibrosis clinics.
Inclusion: Age 0-90 years old; Signed a written informed consent; Confirmed CF diagnosis via genetic test or elevated Immunoreactive Trypsinogen (IRT) level in newborn screen.
Exclusion: History of skin disorders (eczema, psoriasis, etc.) that could prevent sweat testing on the forearms.
