Versalab Auto: Comprehensive Non-Invasive Vascular Laboratory Diagnostics for the Modern Diabetic Vascular Centre
The Clinical Imperative for Advanced Non-Invasive Vascular Diagnostics
The vascular complications of diabetes mellitus — encompassing peripheral arterial disease, microvascular insufficiency, and accelerated atherosclerosis — represent a continuum of pathology that demands a correspondingly sophisticated diagnostic infrastructure. For tertiary hospitals, vascular surgery units, and specialist diabetic foot centres, basic ABI screening, while necessary, is frequently insufficient for the level of vascular anatomical and haemodynamic detail required to guide treatment decisions including revascularisation planning, post-procedural surveillance, and critical limb ischaemia management.
Versalab Auto from Diabetik Foot Care India Pvt Ltd, Chennai is a fully automated, multi-modality non-invasive vascular laboratory system designed to provide the complete diagnostic data set required for comprehensive peripheral vascular assessment in one integrated platform.
Multi-Modality Assessment: The Versalab Auto Diagnostic Portfolio
Versalab Auto integrates multiple non-invasive vascular assessment modalities within a single workflow-optimised platform:
1. Ankle-Brachial Index (ABI)
Automated Doppler based sequential four-limb ABI measurement with bilateral comparison, interpretive classification, and tracking over serial visits.
2. Segmental Limb Pressure (SLP)
Multi-cuff sequential segmental pressure measurement at thigh, calf, ankle, and digital levels, enabling anatomical localisation of stenotic or occlusive disease to aorto-iliac, femoro-popliteal, or tibio-peroneal segments. Essential for pre-operative vascular surgical planning.
3. Pulse Volume Recording (PVR)
Pneumoplethysmographic waveform acquisition at each segmental level, providing qualitative and semi-quantitative assessment of pulsatile blood flow. PVR waveform morphology analysis (triphasic, biphasic, monophasic, flat) enables arterial stenosis characterisation even in the presence of medial arterial calcification — a significant limitation of pressure-based indices in the diabetic population.
4. Toe-Brachial Index (TBI)
Photoplethysmography-based digital artery pressure measurement for TBI calculation — the reference standard for vascular assessment in diabetic patients with ABI values greater than 1.4 due to arterial non-compressibility. TBI values below 0.6 are associated with significantly elevated ulceration and wound healing risk, and below 0.3 indicate critical digital ischaemia.
Clinical Applications and Patient Pathways
Versalab Auto is designed to support the following vascular diagnostic pathways:
• New patient vascular assessment in diabetic foot clinics — full lab protocol
• Pre-operative mapping prior to peripheral vascular intervention or bypass surgery
• Post-intervention surveillance following angioplasty, stenting, or bypass
• Chronic limb-threatening ischaemia (CLTI) staging and treatment response monitoring
• Diabetic foot ulcer assessment for wound healing potential determination
• Claudication severity assessment with treadmill exercise ABI protocol
Reporting, Connectivity, and Quality Assurance
Versalab Auto generates comprehensive structured vascular laboratory reports for each patient encounter, incorporating numerical data, waveform traces, and interpretive classifications. Reports are formatted to clinical vascular laboratory standards and are suitable for inclusion in patient medical records, multidisciplinary team discussions, and referral communications to interventional radiology or vascular surgery.
Summary
Versalab Auto provides the complete non-invasive vascular diagnostic capability required by specialist vascular and diabetic foot centres to deliver guideline-compliant, clinically rigorous peripheral vascular assessment. By consolidating ABI, SLP, PVR, and TBI measurement into a single integrated platform, Versalab Auto enables vascular teams to make informed, data-driven decisions across the full spectrum of diabetic peripheral vascular disease — from early PAD screening to pre-operative revascularisation planning and post-procedural outcome monitoring.
