Every sudomotor reading is only as clean as the electrode that captures it. For independent practices running the CMAT Advantage™ system, disposable skin electrodes are the small consumable that quietly determines whether each test is consistent, sanitary, and easy to stand behind. Here’s what to know about CMAT Advantage electrodes — what they measure, why they’re single-use, and how to keep every exam room stocked.
1. What CMAT Advantage electrodes are used for
CMAT Advantage disposable skin electrodes make the skin contact the system uses to record galvanic skin response (GSR) during sudomotor testing. Sudomotor testing looks at how the small nerve fibers that regulate the sweat glands are working. Because those small fibers are often among the first affected in conditions like diabetes, the test gives clinicians an objective data point when they evaluate at-risk and symptomatic patients — for example, people with diabetes, metabolic risk factors, or unexplained neuropathy symptoms — for early signs of autonomic dysfunction. The CMAT Advantage system is built on FDA-cleared component devices, and the electrode is the piece that actually captures the signal, so a clean, well-adhered electrode directly affects how reliable each reading is.
2. Why single-patient, single-session use matters
These electrodes are single-patient, single-session disposables, and using a fresh set every time protects two things at once. The first is accuracy: adhesive breaks down, conductive gel dries out, and a reused electrode can add noise or drift to a signal that depends on clean, consistent skin contact. The second is infection control: a new electrode per patient removes any cross-contact between people. Stretching a pack by reusing electrodes is a false economy — it risks the reliability of the reading, and your infection-control standards, to save a part that costs about $1.67.
3. What’s in each pack
- 120 disposable skin electrodes per pack
- $200 one-time (about $1.67 each)
- Single-patient, single-session use
- Roughly one set per patient session — about 120 sessions per pack
The CMAT Advantage and TM-Flow systems use the same compatible electrodes, so there is only ever one product to reorder.
4. Never run out with Subscribe & Save
Buying a pack at a time works, but most practices would rather not track it. With Subscribe & Save, electrodes arrive automatically every 1, 2, or 3 months at $185, $190, or $195 per pack — a standing discount off the $200 one-time price — and you can skip a delivery or cancel anytime. For a busy testing schedule, a standing order is the simplest way to make sure supplies are never the reason a test gets rescheduled.
5. Frequently asked questions
Are these electrodes compatible with the CMAT Advantage?
Yes. They are intended for use with the CMAT Advantage (also branded TM-Flow) system for sudomotor testing.
Can I reuse electrodes between patients?
No. They are single-patient, single-session disposables; reuse is not recommended and can compromise both test accuracy and infection control.
How often should I reorder?
It depends on your testing volume. At roughly one set per session, a 120-count pack covers about 120 patient sessions — and Subscribe & Save lets you match delivery frequency to that pace automatically.
