Smart ABI Testing in New Canaan, CT
Smart ABI (Ankle-Brachial Index) testing is a quick, painless, and highly informative diagnostic tool used to assess blood flow in the legs and feet. By comparing blood pressure measurements at the ankle to those at the arm, this non-invasive test helps identify peripheral artery disease (PAD) — a condition in which narrowed arteries restrict blood flow to the lower extremities.
At New Canaan Podiatry in New Canaan, CT , Dr. Jennifer Tauber, DPM, uses Smart ABI testing as part of a comprehensive vascular assessment for patients at risk of circulation problems, particularly those with diabetes or a history of slow-healing wounds. Call (203) 548-7688 to schedule your evaluation today.
Book OnlineWhat Is Peripheral Artery Disease (PAD)?
Peripheral artery disease is a common condition caused by the buildup of plaque within the arterial walls, reducing the amount of blood that can flow to the legs and feet. It is estimated to affect more than 8 million Americans. For many patients, PAD is asymptomatic or produces only mild symptoms that are easy to overlook — making objective testing like Smart ABI critical for early detection.
When left undiagnosed and untreated, PAD can contribute to:
- Slow-healing or non-healing wounds and foot ulcers
- Increased risk of infection and gangrene
- Limb-threatening complications requiring amputation prevention intervention
- Elevated risk of heart attack and stroke
For patients with diabetes or peripheral neuropathy, PAD poses an even greater danger because reduced sensation means vascular compromise may go unnoticed until serious damage has occurred.
Who Should Get Smart ABI Testing?
Dr. Tauber recommends Smart ABI testing for patients who:
- Have been diagnosed with diabetes or pre-diabetes
- Are current or former smokers
- Experience leg pain, cramping, or fatigue when walking (claudication)
- Have non-healing wounds, sores, or ulcers on the feet or legs
- Notice that their feet feel cold, numb, or discolored
- Have a history of high blood pressure, high cholesterol, or cardiovascular disease
- Are undergoing evaluation for limb salvage or wound care
What to Expect During Smart ABI Testing
Smart ABI testing is completely non-invasive and takes approximately 10 minutes to complete. During the test, blood pressure cuffs are placed on your arms and ankles. Pressure measurements are taken at each location using a Doppler ultrasound device. The resulting ratio of ankle pressure to arm pressure generates the ABI score, which indicates the degree of arterial flow to your lower extremities.
No needles, no radiation, no discomfort — just clear, clinically valuable information that guides your care.
Smart ABI Testing and Comprehensive Vascular Care
At New Canaan Podiatry, Smart ABI testing is just one component of a comprehensive approach to vascular foot health. When PAD or circulation compromise is identified, Dr. Tauber coordinates care to address the underlying risk factors while providing in-office treatments such as wound management, custom orthotics, and diabetic footwear to protect at-risk feet. In cases where more advanced vascular intervention is needed, she will refer you to the appropriate specialist.
Frequently Asked Questions
What is a normal ABI score?
A normal ABI score falls between 1.0 and 1.4, indicating healthy blood flow. Scores below 0.9 suggest the presence of peripheral artery disease, with lower scores indicating more significant arterial blockage. Scores above 1.4 may indicate arterial stiffness, which is also clinically relevant, particularly in diabetic patients.
Is Smart ABI testing covered by insurance?
Many insurance plans cover ABI testing when it is medically indicated, such as for patients with diabetes, symptoms of PAD, or non-healing wounds. We recommend calling your insurance provider prior to your appointment to confirm your specific coverage.
How long does Smart ABI testing take?
The test takes approximately 10 minutes and can typically be performed during your regular office visit without any special preparation.
Does Smart ABI testing hurt?
No. The test is completely painless. You will feel the brief pressure of blood pressure cuffs inflating on your arms and ankles, similar to a standard blood pressure check.
Can Smart ABI testing detect all circulation problems in the feet?
Smart ABI is an excellent screening tool for detecting significant peripheral artery disease. However, it is one component of a broader vascular assessment. In some cases, Dr. Tauber may also use diagnostic ultrasound or refer you for additional vascular imaging depending on your results and clinical presentation.
What happens if my ABI score is abnormal?
An abnormal score will prompt Dr. Tauber to discuss the findings with you and develop a management plan, which may include lifestyle modifications, coordination with your primary care physician or vascular specialist, and enhanced monitoring of your foot health. For diabetic patients, close follow-up is especially important.
Can poor circulation be treated?
While significant arterial blockage often requires vascular intervention, many patients can improve their circulation through lifestyle changes such as quitting smoking, controlling blood pressure and cholesterol, managing blood sugar, and increasing physical activity. Dr. Tauber will guide you on steps you can take based on your individual ABI results.
