Abi index test (Ankle Brachial Index ), in Visit Clinic

The ankle-brachial index (ABI) is a simple, noninvasive test that compares systolic blood pressure at the ankle with the arm to screen for peripheral artery disease (PAD). Using blood pressure cuffs and a Doppler probe, an ankle/arm ratio is calculated; normal is about 1.0–1.4. A ratio below 0.9 suggests PAD; a value above 1.4 can indicate stiff, calcified arteries needing further evaluation.

The normal ankle-brachial index (ABI) is about 1.0–1.4. ABI is the ratio of ankle to arm (brachial) systolic blood pressure. Values 0.91–0.99 are borderline and ≤0.90 indicate peripheral artery disease. ABI above 1.4 suggests stiff or non-compressible arteries. It helps assess PAD severity and guide management; abnormal results warrant clinician follow-up and possible further vascular testing.

In India, an ankle‑brachial index (ABI) test generally costs between ₹300 and ₹2,000. Prices vary by city, clinic or hospital, and whether Doppler equipment or specialist consultation is included; government hospitals and diagnostic chains are usually cheaper, while private hospitals or comprehensive vascular assessments cost more. Always confirm final charges with the facility beforehand.

Ankle–brachial index (ABI) testing is noninvasive and generally not painful. It uses blood-pressure cuffs on the arms and ankles and a Doppler probe to measure pulses; cuff inflation can cause brief tightness or mild discomfort similar to a blood-pressure reading. Most people feel only temporary pressure; no needles or lasting pain are involved. If you have severe artery disease, you may notice some leg discomfort during the test.

A good ankle-brachial index (ABI) is generally between 1.0 and 1.4. An ABI of 0.91–0.99 is borderline; ≤0.90 suggests peripheral artery disease. An ABI >1.4 indicates stiff, calcified arteries that may need further vascular assessment. These thresholds apply across ages, though PAD becomes more common with advancing age and risk factors—consult your clinician if your ABI is outside the normal range.

The best treatment for blocked leg arteries (peripheral artery disease) combines lifestyle changes (quit smoking, supervised exercise), medical therapy (antiplatelet agents, statins, blood‑pressure and diabetes control, cilostazol for claudication), and, if symptoms persist or limb is threatened, revascularization (angioplasty/stenting or bypass) plus wound care. Choice depends on severity, anatomy, and overall health—see a vascular specialist.
