ABI and TBI Testing Simplified with Falcon

Peripheral Arterial Disease (PAD) is a widespread yet underdiagnosed condition that affects millions of people worldwide. Early detection is crucial, as untreated PAD can lead to heart attacks, strokes, and limb amputations. Two of the most important diagnostic tools for identifying PAD are the Ankle-Brachial Index (ABI) and Toe-Brachial Index (TBI) tests.

While these tests are highly effective, traditional methods can be time-consuming, operator-dependent, and sometimes inconsistent. That’s why the Falcon Peripheral Vascular Diagnostic (PVD) system from Image Monitoring USA is transforming how clinics and primary care practices approach vascular testing. By automating ABI and TBI testing, Falcon improves accuracy, reduces testing time, and makes PAD screening more accessible than ever.

The Role of ABI and TBI in PAD Detection

What is ABI Testing?

The Ankle-Brachial Index compares blood pressure in the ankle with blood pressure in the arm. A lower ratio indicates restricted blood flow to the legs—a common sign of PAD. ABI is widely recognized as a first-line, non-invasive test for PAD and is recommended by numerous clinical guidelines.

What is TBI Testing?

The Toe-Brachial Index works on the same principle but measures blood pressure in the toes instead of the ankle. TBI is especially valuable for patients with calcified arteries, such as those with diabetes or chronic kidney disease, where ABI measurements may be less reliable.

Together, ABI and TBI provide a complete picture of limb perfusion, helping clinicians diagnose PAD early and accurately.

Challenges with Traditional Testing

Although ABI and TBI testing are essential, conventional methods have limitations:

Operator Dependency: Accuracy often depends on the skill and experience of the technician.
Time-Consuming: Manual testing can take longer, reducing patient throughput in busy clinics.
Variability: Different clinicians may obtain slightly different results, impacting consistency.

These challenges can discourage routine screening, leaving many patients undiagnosed until PAD progresses.

How Falcon Simplifies ABI and TBI Testing

The Falcon PVD system solves these challenges by introducing automation and advanced software into the testing process. Key benefits include:

Automated Measurements: Minimizes operator variability and ensures reproducible, reliable results.
Faster Testing: Streamlined protocols reduce test time, enabling clinics to serve more patients.
Diagnostic Completeness: ABI and TBI testing integrated in one system, along with additional vascular assessments.
Ease of Use: Designed for primary care and vascular labs, Falcon requires minimal training to operate effectively.
Patient Comfort: Non-invasive, radiation-free testing that can be performed quickly at the bedside or in-office.

By removing barriers to routine screening, Falcon makes it easier for healthcare providers to adopt PAD testing as part of standard preventive care.

Making PAD Screening More Accessible

With its time-saving automation and clinical accuracy, the Falcon PVD system empowers busy clinics, primary care offices, and vascular labs to detect PAD earlier. By simplifying ABI and TBI testing, more patients can benefit from routine vascular screening—before complications like stroke, heart attack, or amputation arise.

For patients, this means peace of mind and better long-term outcomes. For providers, it means improved efficiency, greater diagnostic confidence, and the ability to deliver high-quality vascular care to more people.
