Overview of the Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb
The Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb service combines duplex ultrasound of the arteries in both legs with Ankle Brachial Pressure Index measurements.
Together, these investigations provide both anatomical and physiological information about lower-limb circulation.
Duplex ultrasound examines the arteries directly and evaluates blood-flow velocity and waveform patterns.
ABPI compares systolic blood pressure measured at the ankles with systolic blood pressure in the arms.
A lower ankle pressure can indicate reduced blood supply caused by peripheral arterial disease.
NICE includes ABPI as part of the assessment of people with suspected lower-limb peripheral arterial
Combining arterial ultrasound with ABPI can provide a broader assessment than either measurement alone.
This two-limb examination is useful when symptoms affect both legs, when there are bilateral vascular-risk concerns or where a comprehensive comparison is required.
The service is performed at home in London.
What Does the Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb Assess?
Lower-limb arteries
Assesses accessible major arteries supplying both legs.
Arterial stenosis
Detects narrowing that disrupts blood flow.
Arterial occlusion
Identifies selected segments where blood flow is absent.
Doppler waveforms
Evaluates the quality of arterial flow through both limbs.
Arm systolic pressure
Blood pressure is measured at the brachial artery for comparison.
Ankle systolic pressure
Pressure is measured at the ankle arteries using Doppler.
Ankle Brachial Pressure Index
The ankle pressure is compared with the arm pressure to provide an objective indicator of lower-limb arterial circulation.
Who May Benefit From the Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb?
People with walking-related pain in both legs - Intermittent claudication can occur with peripheral arterial disease.
People with reduced pulses in both feet - Doppler and ABPI can objectively assess lower-limb circulation.
People with non-healing wounds or ulcers - Arterial perfusion is important for tissue healing.
People with diabetes and suspected vascular disease - A broader vascular assessment may be required.
People with known PAD - Doppler and ABPI can help monitor severity.
People being assessed before compression therapy - Arterial circulation may need to be established before strong compression is used.
People with cardiovascular risk factors and compatible leg symptoms - Smoking, diabetes and atherosclerotic disease can increase PAD risk.
Symptoms and Reasons to Consider the Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb
Pain in the calves or thighs while walking - Reduced blood flow can cause intermittent claudication.
Cold feet - Poor arterial supply can lower distal skin temperature.
Slow-healing foot wounds - Inadequate circulation can delay healing.
Weak foot pulses - PAD can reduce palpable arterial pulsation.
Rest pain in the feet - Severe arterial disease can produce pain even without walking.
Changes in skin or toenails associated with poor circulation - Chronic PAD can alter tissue quality.
A requirement to assess arterial safety before compression - ABPI is frequently used in this context.
Severe persistent foot pain at rest, gangrene, sudden coldness or colour loss, new numbness or weakness requires urgent vascular assessment.
A normal or high ABPI does not reliably exclude PAD in every person with diabetes, because arterial calcification can make vessels difficult to compress.
How to Prepare for the Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb
ABPI is most reliable when performed after an appropriate period of rest.
This service is provided at home.
What Happens During the Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb?
Is the Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb Safe?
Both ABPI and Doppler ultrasound are non-invasive.
There is no ionising radiation.
Blood-pressure cuffs temporarily tighten around the arms and ankles and can feel uncomfortable, particularly if the legs are already painful.
Ultrasound itself uses sound waves and does not require contrast.
How to Book Your Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb

Provide your London address.
Provide vascular information
Include walking symptoms, wounds, previous PAD and vascular treatment.
Prepare both legs and arms
Wear loose clothing and remove compression garments where instructed.
Home vascular assessment

The authorised vascular report is delivered securely.
When Will I Receive My Results?
The current reporting turnaround is approximately 1 day after the examination.
The report can include ABPI measurements together with duplex findings such as arterial stenosis, occlusion and abnormal blood-flow patterns.
Significant abnormalities may require vascular specialist assessment.
Understanding Your Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb Results
An ABPI around 1.0 to 1.4 is generally considered compatible with normal arterial pressure, although laboratories and vascular services can use slightly different interpretive thresholds.
A lower result can indicate peripheral arterial disease.
Very low values can indicate more severe arterial insufficiency.
An unusually high ABPI can occur when arteries are stiff or calcified and difficult to compress.
This is particularly relevant in diabetes and chronic kidney disease.
The duplex ultrasound provides additional anatomical information and helps identify where arterial narrowing is located.
The combined results should therefore be interpreted together rather than relying on the ABPI number alone.
What Can the Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb Detect?
Peripheral arterial disease - Reduced ankle pressure and abnormal Doppler flow can support diagnosis.
Arterial stenosis - Ultrasound can identify areas of narrowing.
Arterial occlusion - Complete blockage can be demonstrated.
Reduced perfusion in either leg - ABPI provides an objective pressure comparison.
Asymmetry between the two legs - Bilateral measurement enables direct comparison.
Post-treatment arterial changes - Selected vascular interventions can be monitored.
Limitations of the Peripheral Arterial Doppler Ultrasound and ABPI-Two Limb
ABPI can be misleading in calcified vessels - Normal or high results do not completely exclude PAD in some people with diabetes.
Ultrasound can be technically limited in deep or heavily calcified arteries - Additional imaging may be needed.
Microvascular disease is not fully assessed - The test focuses mainly on larger arterial vessels.
Further imaging may be needed before treatment - CT or MR angiography can provide more detailed vascular mapping.
The result does not explain every cause of leg pain - Neurological and musculoskeletal causes remain possible.
