The only device that combines autonomic, vascular, and sudomotor testing in a single 15-minute session — eliminating the need for multiple devices and appointments.
A complete diagnostic session in 15-20 minutes with immediate interpretive reporting — vs. 30-45 minutes for manual autonomic reflex screening.
Bill 95921-95924 for ANS testing plus 93922-93971 for vascular — capturing revenue that single-modality devices like SUDOSCAN cannot.
Backed by three decades of clinical evidence and FDA clearance — the longest track record among comparable ANS testing platforms.
