There are 4 core technologies associated with most ANS testing devices.

These technologies act as diagnostic tools to collect important data from the vital signs of the patient.

These technologies are as follows:

SweatC – Galvanic Skin Response which is used to diagnose small fiber neuropathy

ES-BC – Bioimpedance Analysis which is used to detect body composition

LD-Oxy/Pulse Oximeter – Photoplethysmography (PTG) which is used to diagnose endothelial dysfunction, cardiac autonomic dysfunction, cardiac autonomic neuropathy and to assess overall fitness

TBL/ABI – Brachial and Ankles Volume Plethysmography which used for blood pressure analysis and to detect peripheral artery disease. All of these technologies are FDA cleared and billable to most public and private insurance payers.
