Ankle Brachial Index Test: Diagnosing Peripheral Artery Disease

At American Endovascular, we are dedicated to providing top-tier diagnostic services to support your vascular health. One of our key diagnostic tools is the ankle-brachial index (ABI) test, a simple, non-invasive procedure used to measure the blood pressure in the lower legs compared to the blood pressure in the arms. The test is crucial for detecting peripheral artery disease (PAD), a condition where the arteries in the legs are narrowed or blocked, reducing blood flow to the lower extremities. PAD can lead to pain, mobility issues, and in severe cases, critical limb ischemia, which can result in the need for amputation if left untreated. Early detection through the ABI test can help manage symptoms and reduce your risk of serious complications.

Candidates for the ABI Test

PAD affects millions of people worldwide, often going undiagnosed due to subtle or absent symptoms in its early stages. The ABI test is especially recommended for:

  • People over 50 
  • Smokers
  • Diabetics 
  • People with high blood pressure
  • People with high cholesterol 
  • People experiencing leg pain, cramping, or numbness

Benefits of the ABI Test

The ABI test offers numerous benefits for those at risk of or experiencing symptoms of PAD:

  • Early detection of PAD
  • Non-invasive and painless
  • Takes only 10-15 minutes to perform
  • Can help determine the severity of PAD
  • Monitors PAD progression

Preparing for Your ABI Test

There’s minimal preparation required for an ABI test. You can prepare for the test by doing the following:

  • Do not exercise 1 hour before the test
  • Do not eat or drink anything with caffeine 
  • Do not smoke or drink alcohol 1 hour before the test
  • Wear loose and comfortable clothing 
  • Continue to take your regular medications that day unless instructed otherwise

How is the Ankle Brachial Index Test Done?

At American Endovascular, the ABI test is conducted by our trained vascular specialists in a comfortable, outpatient setting. The test is quick, usually taking about 10-15 minutes, and involves the following steps:

  • Preparation: You will be asked to lie down and rest comfortably. Blood pressure cuffs are then placed on your arms and ankles.
  • Measurement: The cuffs are inflated to measure the blood pressure at each site. A Doppler ultrasound is used to listen to the blood flow and get accurate pressure readings.
  • Calculation: The ABI is calculated by dividing the blood pressure in the ankle by the blood pressure in the arm. This ratio helps determine if there is any significant blockage or narrowing in the arteries.

Understanding Your Results

The ABI test results are utilized for diagnosing and categorizing the severity of PAD, providing insights into your vascular health.

  • Normal ABI (1.0 – 1.4): Indicates no significant blockage in the arteries and that you do not have PAD. 
  • Borderline ABI (0.91 – 0.99):  Indicates that you are on the borderline of having early-stage PAD.
  • Abnormal ABI (0.90 or less): Indicates that you have mild to moderate PAD and further diagnostic testing and treatment may be necessary.
  • High ABI (above 1.4): Indicates you have severe PAD, including stiff or calcified arteries that require further evaluation.

Why is the ABI Test Important?

PAD is often underdiagnosed because its symptoms can be mistaken for other conditions or attributed to aging. Early detection through an ABI test is crucial because PAD is a significant marker for more widespread cardiovascular disease, including heart attack and stroke.

By identifying PAD early, we can take steps to manage and treat the condition, improving your overall vascular health and preventing severe complications.

Ankle Brachial Index Test Frequently Asked Questions

What is an ABI test done for?

An ABI test is a non-invasive procedure used to diagnose peripheral artery disease. This test involves comparing the blood pressure in the ankle with the blood pressure in the arm to determine the presence and severity of PAD.

What is a normal ABI level?
  • 1.0 to 1.4: Normal
  • 0.91 to 0.99: Borderline
  • 0.41 to 0.90: Mild to moderate PAD
  • 0.40 or less: Severe PAD
What should I do if my ABI test results are abnormal?

If your test results confirm you have PAD, your doctor will discuss treatment options with you, which may include lifestyle changes, medications, or minimally invasive procedures to improve blood flow.

I like the doctor they were kind of pretty thorough he says that he could help me he found out the filter in my abdomen from the surgery I had in 1996 has been clogging my blood flow for 25 years and that’s causing the swelling at every other doctor told me was lymphedema it was not lymphedema it caused the lymphedema because no other doctor took the time or care enough to find out the reason for my leg swelling this doctor was the only one who finally found out and he’s going to see if you could put a stent inside the filter to open it up and and stop my legs from swelling hopefully this will all go good it hasn’t happened yet but I’ll keep you posted thankful for this docto I just pray and hope that it works otherwise I like the doctor very much

I had a good experience with my procedure and Dr. Mobley’s follow-up calls are great. I’ve never had a doctor who has been so concerned about following up after a procedure to see how I’m doing and if there are any post-procedure problems I may have experienced (which there aren’t). I’d highly recommend Dr. Mobley.

He puts his patients before himself, returning calls and e-mails quickly. Not only is he kind and considerate, he is an excellent physician. I had to have a procedure that requires me to be awake, and he talked me through it and kept me at ease. If I could give him more stars, I would.
Super friendly, tentative, once in the procedure rm the sx staff made you feel comfortable, easy,+ answered all questions. David mobley, MD answered all my questions, very informative, caring. I felt confident in his care

This was the best experience I have had in such a long time and I have had quite a few procedures in the past both in patient and out including the procedure I was currently present for. No other surgeon has been so kind, transparent, and gentle. Not only did he personally come out beforehand to provide me with education on my procedure, but he talked me through every step of the way and made me feel so comfortable and relaxed. Not to mention his amazing staff! Despite being extremely nervous they kept me smiling and laughing throughout the whole process. 10/10 would recommend. Thank you so much guys!!
