A color Doppler bilateral lower limbs venous is a non‑invasive ultrasound scan of the veins in both legs that uses color Doppler to visualize blood flow direction and velocity. It detects deep vein thrombosis, venous obstruction, reflux or insufficiency and maps varicose veins. The test is painless, requires minimal preparation, and typically takes 15–45 minutes to perform.

An arterial and venous Doppler test is a non‑invasive ultrasound that uses Doppler sound waves to visualize blood vessels and measure blood flow. It evaluates arterial circulation for narrowing or blockages and venous flow for clots or valve insufficiency. Performed with a transducer over the skin, it yields flow velocities and waveforms to help diagnose peripheral arterial disease, deep vein thrombosis, varicose veins, or circulatory causes of pain and swelling.

Cost of lower limb arterial and venous Doppler varies by country and setting. In India private labs typically ₹800–3,000; in private hospitals ₹2,000–6,000. In the UK it's free on the NHS; private scans cost about £80–£300. In the US uninsured prices range roughly $300–$1,000; insured patients usually pay a co‑pay or coinsurance. Exact price depends on facility, location and test complexity.

Costs vary widely by country and facility. Typical private prices: India about ₹700–₹3,000; UK private clinics roughly £100–£300; US roughly $200–$1,000 for a color Doppler ultrasound. Public health systems often cover the test if referred. Final cost depends on facility, body area scanned, need for contrast, and radiologist reporting. Ask your provider for exact pricing.

A positive Doppler means abnormal blood flow has been detected. Depending on context it may indicate a clot or reduced/absent circulation. Clinicians will order confirmatory imaging, assess severity and risks, start appropriate treatment (for example anticoagulation for deep vein thrombosis), increase monitoring, refer to specialists and schedule follow‑up; urgent intervention or hospital care may be needed if circulation or fetal wellbeing is seriously impaired.

Leg Doppler ultrasound is generally painless and noninvasive. You may feel cool gel and light pressure from the probe, and occasional mild discomfort if the technologist presses on a sore or swollen area. The test uses no radiation, is quick, safe, and well tolerated. If you have significant tenderness or concerns, tell the operator so they can adjust technique for comfort.
