The TM Flow System is a Patented system.
“Over the last 10 years I have purchased two TM FLOW Systems and the VAT from Primary Care Diagnostics. I would recommend them to any of my colleagues. The company is prompt, responsive and very easy to assist with anything our office needs.
“Dr. Aluko, Charlotte, NC

TM Flow System focuses on early detection and follow-up of complications (autonomic nervous system & vascular system) of chronic metabolic diseases such as diabetes.
The TM FLOW System includes the following tests to determine these clinical outcomes and includes:
- Sudomotor function tests – using sympathetic skin response
- Photo-plethysmography analysis – using an oximeter. This includes heart rate variability analysis and spectral analysis of the oximeter waveform.
- Cardiac Autonomic Reflex Tests or EWING Tests: which include valsalva maneuver, deep breathing exercises, postural changes
- Ankle Brachial Index (ABI ) measurement using PPG
