Raynaud's Syndrome Testing
Raynaud's Syndrome testing assesses blood flow changes in response to temperature, helping diagnose and manage this condition characterized by episodic vasospasm of the fingers and toes. Accurate testing is essential for differentiating primary from secondary Raynaud's and guiding treatment.
Raynaud's Syndrome is a vascular disorder marked by episodic constriction of small arteries, usually in the fingers and toes, triggered by cold or stress. This leads to color changes, numbness, and discomfort in the affected areas.
- Can be primary (idiopathic) or secondary (associated with other diseases)
- Episodes are often triggered by cold or emotional stress
- Requires specialized vascular testing for diagnosis
Testing involves exposing the hands or feet to cold and monitoring blood flow using PPG or Doppler sensors. The response is measured as changes in waveform amplitude and recovery time, providing objective data on vascular reactivity.
- Cold challenge or immersion protocol
- Real-time monitoring of digital blood flow
- Automated data capture and analysis
Raynaud's testing is invaluable for:
- Diagnosing and differentiating Raynaud's types
- Assessing severity and monitoring treatment response
- Guiding management and lifestyle recommendations
- Supporting early intervention and improved quality of life
These tests are recommended in clinical guidelines for comprehensive vascular assessment and are a mainstay in vascular labs.
VasoGuard systems streamline Raynaud's testing with automated workflows, high-precision sensors, and intuitive software. Clinicians benefit from real-time data, comprehensive reporting, and seamless integration with EMR systems.
- Automated cold challenge protocol
