Details about Arterial Doppler Unilateral
What is an Arterial Doppler Unilateral Scan?
An Arterial Doppler Unilateral Scan is a specialised vascular ultrasound that evaluates blood flow within the arteries of one arm or one leg. It uses sound waves to measure the speed and direction of blood flow, helping identify arterial narrowing (stenosis), blockages, or reduced circulation.
This scan is commonly used to assess peripheral arterial disease (PAD), circulation problems, or symptoms affecting a single limb. Unlike X-rays or CT scans, Doppler ultrasound does not use radiation and is completely non-invasive.
Focusing on one limb allows for a targeted and detailed assessment of symptoms on the affected side.
When an Arterial Doppler Unilateral Scan is recommended
A unilateral arterial Doppler scan is recommended when symptoms or clinical findings suggest arterial circulation issues in one limb.
You may be referred for this scan if you:
- Have leg pain when walking (claudication)
- Experience coldness or colour changes in one limb
- Have non-healing wounds or ulcers
- Notice reduced pulses in one arm or leg
- Have suspected peripheral arterial disease
- Have diabetes with limb circulation concerns
- Have had vascular surgery or intervention
- Require follow-up imaging on one side only
Benefits of an Arterial Doppler Unilateral Scan
- Assesses arterial blood flow accurately
Measures speed and direction of circulation. - Detects narrowing or blockages
Identifies reduced arterial supply. - Non-invasive and painless
No needles or radiation exposure. - Focused assessment of one limb
Ideal for one-sided symptoms. - Supports diagnosis of peripheral arterial disease
Helps guide management and treatment. - Safe and repeatable
Suitable for monitoring over time. - Guides further investigations or treatment
Informs need for intervention or referral. - Performed by vascular ultrasound specialists
Ensures accurate and reliable results.
How the Arterial Doppler Unilateral Scan is performed
Home-Based Ultrasound Scans (UK-wide)
- Book your ultrasound appointment online or by phone
- A qualified clinician travels to your home or chosen location
- The scan is performed in the comfort and privacy of your home
- Scan duration varies by examination type (typically 10–30 minutes)
- Findings are explained during or shortly after the scan
Important:
All ultrasound scans are provided as home-visit services only. This service is available UK-wide, allowing you to access diagnostic imaging without attending a clinic.
Understanding your Arterial Doppler Unilateral Scan results
Normal arterial flow
Blood flows freely through the arteries with normal velocity and waveform patterns.
Typical report:
- Normal arterial Doppler findings
Reduced blood flow or narrowing
The scan may show slowed flow, turbulence, or narrowing, suggesting arterial disease.
Typical report:
- Evidence of arterial stenosis
Significant blockage
Severely reduced or absent flow may indicate arterial occlusion.
Typical report:
- Arterial occlusion detected
Results are interpreted alongside symptoms and medical history to guide next steps.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
