The ankle brachial index is used to estimate if a person is subjected to the peripheral artery disease (PAD) . The test is performed by measuring the blood pressure (BP) in lower legs and arms and is calculated by dividing the systolic pressure in ankles with systolic pressure in arms. It is also called as ABI or Ankle Brachial Pressure Index or ABPI. Find your ABPI using this ABI calculator.

If the ankle and brachial SP is 21 and 23 mmHg, then
ABI = ( 21 / 23 )
= 0.91
Since your ABI value is 0.91 you are in Borderline of PAD.
