Ankle-Brachial Index (ABI)
The ankle brachial index test is a simple, painless test to help your physician determine if you have peripheral vascular disease (PVD). The blood pressure in your arms and ankles is checked using a regular blood pressure cuff and a special ultrasound stethoscope called a Doppler.
The pressure in your foot is compared to the pressure in your arm to determine how well your blood is flowing and whether further tests are needed.
