ShareThe Ankle Brachial Index test is performed at Geelong Veins Skin & Laser by our nurses and doctors. The ABI test is a non invasive 10minute test that screens for Peripheral Arterial Disease by comparing blood pressure in the arms to blood pressure in the legs. Peripheral arterial disease (PAD) is a cardiovascular disease characterised by narrowing or blockage of the arteries – the blood vessels taking blood to your legs.
Who Should Get an Ankle-Brachial Index (ABI) Test for Peripheral Arterial Disease (PAD)?
ABI Testing is recommended for individuals with any of the following risk factors or symptoms:
- Age over 65
- Current or former smoker
- High blood pressure or taking blood pressure medication
- High cholesterol or on lipid-lowering therapy
- Diagnosed with diabetes
- History of angina, heart attack, stroke, or ischaemic heart disease
What Are the Common Symptoms of Peripheral Arterial Disease (PAD)?
Peripheral Arterial Disease (PAD) often presents with subtle but progressive symptoms. Key signs to watch for include:
- Cramping or pain in one or both calves after walking a certain distance (intermittent claudication)
- Leg pain at night that causes you to get up or hang the leg out of the bed for relief
- Non-healing leg ulcers or wounds
- Recurrent leg rashes or brown skin discolouration
- Persistent numbness or coldness in one or both legs
- Hair loss on the lower legs or feet
What Does the Ankle-Brachial Index (ABI) Test Involve?
The ABI test is a simple, non-invasive procedure used to assess your risk of Peripheral Arterial Disease (PAD). During the test, you’ll lie comfortably on your back while four blood pressure cuffs are placed around your arms and ankles. These cuffs inflate and deflate in sequence over 3–5 minutes. The test compares the blood pressure in your legs to the pressure in your arms to calculate an ABI score. Your doctor will interpret this score to determine your risk of PAD and whether further vascular investigations are needed.
What Is Peripheral Arterial Disease (PAD)?
Peripheral Arterial Disease (PAD) is a condition where the arteries that carry blood to your arms and legs become narrowed or blocked, reducing blood flow to your limbs. When this happens, your muscles and skin may not receive enough oxygen and nutrients, leading to symptoms such as leg pain, skin changes, muscle fatigue, and hair loss on the lower limbs.
What Happens If My ABI Test Result Is Abnormal?
If your ABI test shows an abnormal result, it means there may be reduced blood flow to your limbs. The next step is usually an arterial ultrasound to assess the arteries in more detail. This scan can be arranged by your GP or one of our doctors, depending on who referred you for the ABI test.
Why Do I Need an Arterial Test if I’m Seeking Vein Treatment?
If you have one or more risk factors for Peripheral Arterial Disease (PAD), it’s important to assess the health of your arteries before beginning any vein treatment. Poor arterial circulation can impair healing and increase the risk of complications such as ulcers, skin breakdown, or delayed recovery. Early detection of PAD is crucial, as untreated cases can lead to leg cramps, night-time pain, chronic wounds, gangrene, and in severe cases, amputation.
What Is the Cost of ABI Testing and Is There a Medicare Rebate?
The cost of an Ankle-Brachial Index (ABI) test is $85, with a Medicare rebate of $61.70 available. If you hold a valid concession card, you will be bulk billed, meaning there is no out-of-pocket cost.
