Ankle Brachial Index
Assessing Blood Flow for Early Detection of Vascular Health
How does the ABI test work?
The ABI test compares the blood pressure measured at the ankle with the blood pressure measured at the arm
The ankle-brachial index (ABI) test available at Dr. RK’s is a quick and simple way to check for peripheral artery disease (PAD). PAD occurs when narrowed arteries reduce blood flow to the arms and legs. PAD can cause leg pain when walking, and it also increases the risk of heart attack and stroke.
Who should get an ABI test?
The ABI test is recommended for people who have risk factors for PAD, such as
Age 50 or older
Smoking
Diabetes
High blood pressure
High cholesterol
Family history of PAD
How to prepare for an ABI test
There is no special preparation needed for an ABI test. However, you should wear comfortable clothing and avoid wearing jewellery on your ankles or arms.

What to expect during an ABI test
Our Physicians will place blood pressure cuffs on your ankles and arms during an ABI test. We will then take your blood pressure at each location. The results of the blood pressure readings will be used to calculate your ABI
What do the results of an ABI test mean?
An ABI of 1.0 or higher is considered normal. An ABI of 0.9 or lower may indicate PAD. An ABI of 0.7 or lower is considered severe PAD.
If you have a low ABI, what should you do?
If you have a low ABI, we will recommend lifestyle changes to improve your blood flow, such as quitting smoking, exercising regularly, and eating a healthy diet. We also prescribe medication to lower your blood pressure or cholesterol.
