A Multi-Center Study of A New Method of Sweat Testing: The CF Quantum® Sweat Test
Study Overview

Conditions
Intervention / Treatment
Detailed Description
The primary objective is to evaluate the diagnostic accuracy of a new sweat test method in both normal individuals and individuals with CF or cystic fibrosis related metabolic syndrome (CRMS).
Subject participation is for one day and duration of study for each subject is one day. No follow-up will be required.
Number of subjects; 300 split evenly between subjects with previously diagnosed CF or CRMS (cystic fibrosis related metabolic syndrome) and subjects referred to the sweat test lab for clinical reasons.
Number of sites = 6, U of WI-Madison, U of WI-Milwaukee, U of MI-Ann Arbor, Dayton Children's Hospital (OH), U of MN, and Children's of Alabama.
Primary endpoints:
- Clinical and analytical sensitivity of the new test method
- Clinical and analytical sensitivity of the standard-of-care methods
Statistics Sensitivity and specificity will be calculated and reported along with the corresponding 95% confidence intervals. Bias assessment will be conducted according to the Clinical and Laboratory Standards Institute (CLSI) guidelines for method comparison and bias estimation. Pearson's correlation analysis will be conducted to test for adequate range of the replicate values for the new test method.

Description
Inclusion Criteria:
- Patients referred to the sweat test lab on a clinical basis.
- Infants who require a sweat test as follow-up to an abnormal CF screening test.
- Patients who have already been diagnosed with CF or CRMS.
- Written informed consent (and assent when applicable) obtained from subject or subject's legal representative.
Exclusion Criteria:
- Patient is receiving oxygen by open delivery.
- Infants less than 48 hours of age.
- Diffuse inflammation or rash on the collection site.
- Patients who have had a reaction to a prior iontophoretic sweat test procedure.
- Arm is too small for both the new and conventional sweat test.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
CF/CRMS
Subject's with a previous cystic fibrosis or cystic fibrosis related metabolic syndrome (CRMS) diagnosis will receive the institution's standard iontophoresis sweat testing (Gibson-Cooke or Wescor Macroduct) to provide a diagnosis. The patient will also receive a sweat test provided by the new CF Quantum Sweat Test System which includes the same process and principal of operation of iontophoretic stimulation, collection and analysis of sweat compared to the standard. The results of the new sweat test and the standard sweat test will be compared. The new sweat test will not be used to diagnose, treat or mitigate the patient's condition. Results are used only to compare to the standard of care. |
The intervention is iontophoretic sweat testing which includes the stimulation, collection and analysis of sweat.
The standard of care sweat testing used at each institution will be compared to a new iontophoresis sweat test called the CF Quantum.
|
NON CF/CRMS
Subject's without a previous cystic fibrosis or cystic fibrosis related metabolic syndrome (CRMS) diagnosis but referred to the sweat test lab on a clinical observation basis by a physician will receive standard iontophoresis sweat testing (Gibson-Cooke or Wescor Macroduct) to provide a diagnosis. The patient will also receive a sweat test provided by the new CF Quantum Sweat Test System which includes the same process and principal of operation of iontophoretic stimulation, collection and analysis of sweat compared to the standard. The results of the new sweat test and the standard sweat test will be compared. The new sweat test will not be used to diagnose, treat or mitigate the patient's condition.
