Symptom
Insufficient sweat rate or insufficient
sweat for Sweat Analysis to
complete.
(See also Error Message
Troubleshooting below.)
Nanoduct resets during a test.
Iontophoresis process stops
prematurely.
Probable Causes / Possible Solutions
Probable Causes:
Insufficient sweat may occur for a variety of reasons and varies
depending upon patient. Physiological factors, such as the patient's
age, weight, race, and hydration level may contribute to insufficient
sweat, as well as other physiological factors (e.g. anhidrosis,
hypohidrosis).
Possible Solutions:
If an adequate sweat sample is not obtained, repeat testing should
occur as soon as is practical. This could be the same day or the
following day. The sweat test should only be repeated once on any
given day.†
The patient should be well hydrated and free of acute illness.
Check that the Pilogel is within the expiration date.
Probable Causes:
Low battery voltage.
Electrostatic discharge to the Nanoduct's face, enclosure,
connectors, or electrodes may cause the Nanoduct to reset (see
Appendix J).
Possible Solutions:
Replace all four batteries.
Repeat the sweat test one time.†
If the problem persists, contact ELITechGroup for further instructions.
Probable Causes:
Low battery voltage.
Electrodes not properly latched with locking ring or cable becoming
detached from Nanoduct.
Holders not adequately secured to patient.
Damaged electrode cable assembly.
Possible Solutions:
Replace all four batteries.
Ensure both electrodes are latched with locking ring and that the
cable is properly connected to the Nanoduct.
Ensure holders are secured with adequate tightness to the patient's
limb. Do not overtighten and impede blood circulation.
Inspect the electrode cable assembly for any damage. Do not use
electrodes if there is any damage to the cable insulation or if there
are exposed bare wires.
Repeat the sweat test one time.†
If the problem persists, contact ELITechGroup for further instructions.
