When do you order an ABI?
Others recommend that the ABI be used in people from 50-70 years of age with at least one recognized cardiovascular risk factor, such as smoking, low HDL, high total cholesterol, or hypertension. The American Diabetes Association suggests that an ABI be obtained on all people with diabetes older than 50.
Why would a doctor order an ABI test?
The ankle-brachial index test is a quick, simple way to check for peripheral artery disease (PAD). The disease occurs when narrowed arteries reduce the blood flow to the arms and legs. PAD can cause leg pain when walking. PAD also increases the risk of heart attack and stroke.
Who should get an ABI?
Candidates for an ankle-brachial index test Ask your doctor if you should have this test if you are age 50 or older and have any of these risk factors for PAD: Being a current or former smoker. Diabetes. Overweight (a body mass index of 25 or greater)
What are the criteria of ankle-brachial index and method?
The ankle-brachial index (ABI) is the ratio of systolic blood pressure measured at the ankle - at the pedis dorsalis or posterior tibial artery - divided by the systolic blood pressure measured in the arm at the brachial artery.
What diagnosis covers ABI?
The Ankle Brachial Index (ABI) is the systolic pressure at the ankle, divided by the systolic pressure at the arm. It has been shown to be a specific and sensitive metric for the diagnosis of Peripheral Arterial Disease (PAD).

What are the three classifications of ABI?
Patients are classified as having a mild, moderate or severe ABI according to their level of consciousness at the time of initial assessment. Various measures of altered consciousness are used in practice to determine injury severity.
Can ABI be done without Doppler?
In fact, ABI ratios can be even be calculated without the use of a Doppler pen. In an emergency situation when an ABI machine or a Doppler pen is not available, you can simply grab a portable blood pressure (BP) machine.
What are three signs symptoms that can accompany peripheral vascular artery disease?
Numbness, weakness, or heaviness in muscles. Pain (described as burning or aching) at rest, commonly in the toes and at night while lying flat. Paleness when the legs are elevated. Reddish-blue discoloration of the extremities.
What ABI is safe for compression?
Compression has been used successfully in patients with ABI as low as 0.5. Supervised reduced compression of 15–25 mm Hg has been advised for patients with moderate to severe PAD (ABI 0.5–0.85) and a vascular referral in cases where the ABI < 0.5.
What does an ankle-brachial index of 0.6 0.9 indicate?
If your ABI is 0.9 or lower, you have PAD. You should make an appointment with a vascular medicine specialist. A low ankle-brachial index means you have a higher risk of: Heart attack.

Vascular pain often feels like an uncomfortable heaviness or throbbing sensation. It can also feel like an aching sensation. It usually affects your legs and can be worse with walking or exerting yourself.
What is the treatment for blocked arteries in the legs?
A graft is used to redirect blood flow around a blocked or narrowed artery. A graft can be a blood vessel from another part of the body or a synthetic substitute. In some cases, angioplasty or surgery may be necessary to treat peripheral artery disease that's causing claudication: Angioplasty and stent placement.
Can you have blocked arteries in your legs?
The arteries in your legs and feet can get blocked, just like the arteries in your heart. When this happens, less blood flows to your legs. This is called peripheral artery disease (PAD). If your leg arteries are badly blocked, you may develop foot pain while resting or a sore that won't heal.

What Is a Normal Ankle Brachial Index? - eMedicineHealth
The ankle-brachial index (ABI) is a procedure done to evaluate a patient for peripheral arterial disease (PAD) in the legs. The ankle-brachial index test is a noninvasive procedure that evaluates the blood flow through the arteries of the legs by checking blood pressure readings. An ABI of 1.0-1.40 is considered normal.
Why do you need an ABI?
You also might need an ABI to check the severity of your PAD. Your provider might order this test every year, to see if your condition is getting worse. If you’ve had surgery on the blood vessels of your legs, your provider might want an ABI to see how well blood is flowing into the leg.
What is an ankle brachial index test?
The ankle brachial index, or ABI, is a simple test that compares the blood pressure in the upper and lower limbs. Health care providers calculate ABI by dividing the blood pressure in an artery of the ankle by the blood pressure in an artery of the arm. The result is the ABI. If this ratio is less than 0.9, it may mean that a person has peripheral artery disease (PAD) in the blood vessels in his or her legs.
What happens during an ankle brachial index test?
The test is very similar to a standard blood pressure test. Ask your healthcare provider about what you can expect. In general, during your ABI test:
What is systolic pressure?
The systolic pressure is the pressure at which the blood flow is heard again. That is the part of the blood pressure measurement needed for the ABI. The technician will repeat this process on your other ankle and on both of your arms. Next, the technician will calculate the ABI.
What does it mean when your ABI is less than 0.9?
The result is the ABI. If this ratio is less than 0.9, it may mean that a person has peripheral artery disease (PAD) in the blood vessels in his or her legs. In PAD, plaque builds up in the arteries. It often affects the vessels that bring blood to the legs. The reduced blood flow can cause pain and numbness.
What does a blood pressure technician do?
A technician takes your blood pressure in both of your arms using an inflatable cuff, similar to the one used in the doctor’s office. The technician also measures the blood pressure in the ankles. The doctor uses these values to compute your ABI.
How to get blood flow to your legs?
Eating a healthy diet. Taking medicine to increase blood flow to your legs or to prevent blood clots. Having procedures to restore blood flow, like angioplasty. Having surgery to your leg (if the blockage is severe) Talk to your provider about what your ABI value means for you.
Why do you need a brachial index test?
Your doctor might also recommend an ankle brachial index test if you’ve been experiencing leg pain when walking, which can be a symptom of PAD. Another possible reason to get a test is if you’ve undergone surgery on the blood vessels of your legs, so your doctor can monitor the blood flow to your legs.
What is the ABI test?
An ankle brachial index test, also known as an ABI test, is a quick and easy way to get a read on the blood flow to your extremities. It is a test that your doctor can order if they are concerned you may have symptoms of peripheral artery disease, or that you may be at risk for this condition. This test can be very useful as one component ...
Why is ABI test important?
The ABI test is particularly useful because it’s noninvasive and easy to conduct.
Where to put blood pressure cuff?
The technician will start by putting a blood pressure cuff on one arm, usually the right arm. They will then rub a little gel on your arm right above your brachial pulse, which is just above the inside crease of your elbow. As the blood pressure cuff inflates and then deflates, the tech will use the ultrasound device or Doppler probe to listen for your pulse and record the measurement. This process is then repeated on your left arm.
How does a blood pressure test work?
A technician will take your blood pressure in both arms and in both ankles, using an inflatable cuff and a handheld ultrasound device to hear your pulse.
What is PAD in advanced stages?
In advanced stages, PAD progresses to chronic limb threatening ischemia (CLTI) in which patients have rest pain (continual, burning pain) from lack of blood flow and/or develop non healing wounds. CLTI patients have a dramatically higher rate of amputation compared to patients with intermittent claudication.
What is the normal range for ABI test results?
Experts consider a normal range for an ABI test result to fall between 0.9 and 1.4.
How to calculate ABI?
The ABI value is determined by taking the higher pressure of the 2 arteries at the ankle, divided by the brachial arterial systolic pressure. In calculating the ABI, the higher of the two brachial systolic pressure measurements is used. In normal individuals, there should be a minimal (less than 10 mm Hg) interarm systolic pressure gradient during a routine examination. A consistent difference in pressure between the arms greater than 10mmHg is suggestive of (and greater than 20mmHg is diagnostic of) subclavian or axillary arterial stenosis, which may be observed in individuals at risk for atherosclerosis.
How to measure brachial pressure?
Measuring the brachial pressure. The patient should be in the supine position. Place the blood pressure cuff on the arm, with the limb at the level of the heart. Place the ultrasound gel in the ante cubital fossa over the patient's brachial pulse.
What is ankle brachial index?
The Ankle Brachial Index (ABI) is the systolic pressure at the ankle, divided by the systolic pressure at the arm. It has been shown to be a specific and sensitive metric for the diagnosis of Peripheral Arterial Disease (PAD). Additionally, the ABI has been shown to predict mortality and adverse cardiovascular events independent ...
Where to place ultrasound gel?
Place ultrasound gel on the skin overlying the dorsalis pedis (DP) and posterior tibial (PT) arteries in the foot. The Doppler signal of the DP can often be found slightly lateral to the midline of the dorsum of the foot. Using a standard hand-held Doppler probe and the ultrasound gel, locate the signal from the DP.
How many decimal places should an ABI be recorded?
Calculated ABI values should be recorded to 2 decimal places.
Where is the PT signal detected?
Next, measure the systolic pressure of the PT artery. The PT signal is detected posterior to the medial malleolus. Once again, using the Doppler with ultrasound gel, locate the signal, and follow the process described above to measure the PT systolic pressure. Repeat both measurements on the opposite leg.
Which is higher, ankle or arm?
Pressure is normally higher in the ankle than the arm.

An ankle-brachial index (ABI) test is a simple way for your doctor to check how well your blood is flowing in your legs.
What Happens During an Ankle-Brachial Test?
The test lasts 10 to 15 minutes. First, you lie down on a table. Your doctor wraps a cuff around your arm to take your blood pressure. You’ll feel mild pressure while it inflates, but that doesn’t last long.
How Do You Interpret Ankle-Brachial Test Results?
Your doctor uses the blood pressure results to come up with a number called an ankle-brachial index. Here’s what the numbers mean:
How to use ultrasound on arm?
To use the device, your doctor will first put a dab of gel on your arm just below the blood pressure cuff. Then, they’ll put the ultrasound device on the gel. This helps them know when to take your blood pressure reading. They’ll do the same steps on your other arm and then on both ankles.
What happens if you take an exercise ankle brachial index test?
Your doctor will turn to a different test. If you took an exercise ankle-brachial index test, the range of results may be a little different. Your doctor will look at your results, symptoms, and health history to help you decide what comes next. You may need to change your lifestyle or start taking medicine. In some cases, your doctor may say you ...
How does a doctor take blood pressure?
Your doctor wraps a cuff around your arm to take your blood pressure. You’ll feel mild pressure while it inflates, but that doesn’t last long. Your doctor will use a Doppler ultrasound device, a plastic tool that’s a little smaller than a computer mouse. It connects to a speaker so they can hear your blood flow.
What happens if you have a PAD?
If you have PAD, you’re more likely to have a stroke or heart attack. The ABI test compares the blood pressure at your ankle with the blood pressure at your arm. If you have a low score on this test, you probably have poor blood flow in your legs.
Why do we do ankle brachial index?
Why it's done. The ankle-brachial index test is done to check for PAD — narrowed arteries that reduce blood flow, usually in your legs. Research indicates that PAD affects about 10 percent of people over age 55.
What does PAD mean in blood pressure?
PAD can cause leg pain when walking and increases the risk of heart attack and stroke. The ankle-brachial index test compares the blood pressure measured at your ankle with the blood pressure measured at your arm. A low ankle-brachial index number can indicate narrowing or blockage of the arteries in your legs.
How long does it take to get an ankle brachial index?
The ankle-brachial index test should take only a few minutes. You don't need to follow any special precautions afterward. Your doctor will discuss your test result with you.

Borderline blockage (0.91 to 0.99). An ankle-brachial index number is this range indicates that you have borderline PAD. Your doctor might recommend an exercise ankle-brachial index test.
What test is done for leg pain while walking?
Your doctor might recommend an ankle-brachial index test if you have leg pain while walking or risk factors for PAD, such as:
How long do you have to rest before a blood pressure test?
During the procedure. You likely will be asked to rest for 5 to 30 minutes before the test. Typically, you lie on a table on your back, and a technician measures your blood pressure in both arms and both ankles, using an inflatable cuff and a hand-held ultrasound device that's pressed on your skin.
What to do if you have a blockage in your big toe?
If you have severe diabetes or significantly blocked arteries, your doctor may need to read your blood pressure at your big toe (toe-brachial index) to get an accurate test result. Depending on the severity of your blockage, your doctor may recommend: Lifestyle changes. Medication. Surgery to treat PAD.
What is the ABI of a PAD?
A normal ABI is in the range of 1.1-1.3. When verified by angiography, an ABI <0.9 has a sensitivity and specificity of 95% for PAD. 1 Although there is some controversy concerning the cutoff levels, the ABI can also be used as an indicator of PAD severity. In general, an ABI <0.9 is considered abnormal, and traditional symptoms of claudication are generally seen at 1.3, may also indicate disease.
What is ankle brachial index?
The ankle-brachial index (ABI) is an important noninvasive office test with proven ability to detect peripheral arterial disease (PAD) and predict cardiovascular risk. The ABI is broadly accepted as a screening tool for patients with traditional symptoms of claudication, but there is disagreement over its appropriateness for asymptomatic patients. Clearly there is evidence on both sides of the debate. Read on to see if you and I come down on the same side of the matter.
What are the risk factors for PAD?
NHANES data showed that “traditional” risk factors for CVD can also be useful for predicting PAD, i.e., hypertension, high cholesterol, diabetes, and smoking. NHANES found that 95% of persons with PAD had at least one of these risk factors and that 72% had two or more. Another study found that low kidney function and African-American ethnicity were also risks. 5
How many people have PAD?
About 8 million Americans are thought to have PAD, an atherosclerotic disease of the peripheral vasculature. The most common symptom is chronic leg pain, or intermittent claudication, but 50%-75% of PAD patients are asymptomatic. PAD is a serious disease that can lead to limb ischemia and subsequent amputation. Additionally, patients are at increased risk for cardiovascular morbidity and mortality.
Is ABI a populationwide screening tool?
But as the USPSTF suggests, using the ABI as a populationwide screening tool, without regard to age and other risk factors, would be counterproductive. The effort expended in obtaining universal ABIs would return a low yield and would usually be nonreimbursable by insurance companies.
Can ABI be detected in asymptomatic individuals?
Preventive Services Task Force (USPSTF) advises against ABI screening for asymptomatic PAD. The Task Force found only “fair evidence” that the ABI can detect PAD in asymptomatic individuals. However, they gave the practice a D rating (can potentially cause harm) because of the low prevalence of PAD in the general population, the perceived lack of treatment options, and the potential for unnecessary workups and false positives, which could lead to unnecessary personal hardship and health-care expenditure. 9 The AHA has asked the Task Force to reconsider its recommendation.
Does diabetes decrease ABI?
Another study, which tracked ABIs and TBIs over 10 years, found diabetes to be a significant predictor of a decreased TBI but not of a decreased ABI. This is further evidence to support the use of TBI in diabetic patients. The independent predictors of a decrease in ABI to <0.3 were current smoking and a high ratio of HDL-to-total cholesterol. 7
What is peripheral artery disease (PAD)?
Peripheral artery disease causes poor blood flow to the legs and other parts of the body. This happens when the blood vessels are blocked or narrowed (arteriosclerosis).
What is ankle brachial index?
The ankle-brachial index (ABI) is a simple, noninvasive test for peripheral artery disease (PAD). It can be used to find out if you have PAD and to monitor you if you have PAD. The ABI can show how severe PAD is, but it cannot identify the exact location of the blood vessels that are blocked or narrowed.
How to check for ABI?
Your doctor will talk to you about the follow-up care you need after your ABI test. In general: 1 You may need to have repeat ABI tests from time to time, especially if your ABI is outside of the normal range. Regular testing will help your doctor know if your PAD is getting worse. It can also be used to see how well treatments to open your blood vessels are working. 2 You will need to schedule regular appointments with your doctor if you have PAD. 3 Depending on your results, you may need other testing or treatments.
What does ABI mean in blood work?
What do the ankle-brachial index (ABI) test results mean? The ABI itself is the systolic blood pressure reading (top number) in your ankle divided by the systolic blood pressure reading in your arm. If your ABI is 0.9 or lower, you should make an appointment with a vascular medicine specialist.
What age should I not have an ABI test?
Have diabetes and are over age 50. Are over age 65. Have high cholesterol, high blood pressure or a family history of heart disease. You should not have the ABI test if you have excruciating leg pain, cut (s) on your legs or feet or deep vein thrombosis.
What does a 0.9 ABI mean?
An ABI ratio of 0.9 or less means you have PAD. An ABI ratio between 0.4 and 0.7 means you have moderate PAD. An ABI ratio less than 0.4 means you have severe PAD. An ABI ratio higher than 1.4 could mean the blood vessels in your limbs are stiff due to advanced age or diabetes.
How long does it take to get an ABI?
The ABI is the preferred way to diagnose PAD because it is simple, fast and sensitive. The test takes about 10 to 20 minutes and can be done in your doctor’s office or an outpatient clinic. The test does not cause any long-term problems. Your doctor may want you to have an ABI test if you:
