Ankle Brachial Index

Ankle-brachial index test, a comparison of your blood pressure measured at an ankle and your blood pressure measured at an arm, which can indicate blockage of blood flow to the legs.
After removing your sock and shoes you will lie on an examining bed. The technician will attach blood pressure cuffs to arms, ankles, and toes.  The sonographer will warn you when the cuffs inflate. 
You can take the following steps to prepare for your appointment:

DO NOT wear a long sleeve shirt.

DO NOT wear pantyhose

    An ankle brachial index usually takes about 10 to 15 minutes.
