An arterial and venous Doppler of both lower limbs is a non-invasive ultrasound (duplex) test using Doppler signals to evaluate blood flow in leg arteries and veins. Arterial Doppler detects narrowed or blocked arteries and peripheral arterial disease by measuring flow velocity and waveforms; venous Doppler identifies deep vein thrombosis and venous reflux. It guides diagnosis of leg pain, ulcers, swelling and treatment planning.

Costs vary by country and provider. In the UK the NHS covers it free; private clinics typically charge £100–300. In the US outpatient duplex Doppler for bilateral lower limbs generally ranges $200–1,000. In India private centers often charge about ₹700–3,000. Final price depends on facility, extent of study, reporting fees and insurance—confirm with your local imaging center.

A venous Doppler (ultrasound) is generally painless and noninvasive. A warm gel and a handheld probe are used; you may feel mild pressure or rubbing, especially if the leg is tender from inflammation or a clot. It typically takes 15 to 45 minutes, and the sonographer can adjust pressure to minimize discomfort. No needles, radiation, or recovery time are needed; serious pain is uncommon.

A venous Doppler is a non-invasive ultrasound that evaluates blood flow and vein structure in the legs (or arms). It detects deep vein thrombosis, identifies venous obstruction or valve reflux (venous insufficiency), assesses varicose vein severity, and guides treatment and follow-up (anticoagulation, compression, or surgery). It’s used for symptoms like swelling, pain, redness, or chronic ulcers.

A positive Doppler ultrasound indicates abnormal blood flow — such as reduced, absent, or reversed flow — suggesting conditions like deep vein thrombosis, peripheral arterial disease, or compromised placental/fetal circulation. It typically prompts further evaluation (additional imaging, blood tests) and often leads to treatment — for example anticoagulation for DVT or vascular intervention for arterial blockages — to prevent complications.

Costs vary widely by country and setting. In the UK it's usually free through public health services or about £50–£300 privately. In India typical clinic charges are roughly ₹500–₹3,000. In the US out‑of‑pocket costs commonly range $200–$1,500 (hospital settings may be higher). Final price depends on location, type of Doppler study, and insurance coverage.
