New Sweat Test Device for Cystic Fibrosis

This study is testing a new device called the micro Sweat Test Patch (mSTP or µSTP) for measuring sweat chloride levels. This device aims to improve how we diagnose and monitor cystic fibrosis (CF). Researchers will compare the results from the mSTP to the standard sweat test method. You can join if you are between 2 weeks and 90 years old, have a confirmed CF diagnosis (through a genetic test or high IRT level in newborn screening), and do not have skin conditions that would prevent testing on your forearms. The study will measure sweat chloride concentration using both methods to see if the new device works as well as the standard test. The study is currently recruiting participants.

Study design
This interventional study plans to enroll 300 participants of all ages. It compares a new sweat test device to the standard method.
What's involved
You will undergo both the standard sweat test and the new micro Sweat Test Patch (mSTP) procedure. Sweat chloride will be measured for up to 30-45 minutes after the devices are placed.
Compensation
Not stated in the trial record.
Follow-up
Sweat chloride concentration will be measured for up to 30 minutes after the new device is placed and up to 45 minutes after the standard method.

Eligibility criteria

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

What this trial measures

  • Sweat Chloride Concentration using the sweat test sensorup to 30 minutes post-device placement

    Sweat chloride concentration by the µSTP will be assessed and measured using the sweat test sensor.

  • Sweat Chloride Concentration by SOCup to 45 minutes post-intervention

    Sweat chloride concentrations will be measured using the standard-of-care method, using pilocarpine iontophoresis. The collected sweat samples will be sent for analysis of the chloride concentration. The results from the same participant will be compared to the measurements made with the µSTP device.
