The varicose vein test — medically called venous duplex Doppler ultrasound — is the single most important investigation before any vein treatment. It is non-invasive, painless, takes about 30 minutes, and gives a complete map of which veins are diseased, which valves have failed, and whether the deep venous system is healthy. This guide explains everything you need to know about the test in India.
What the Test Measures
- Direction of blood flow in each major vein
- Reflux (backflow) duration — greater than 0.5 second is pathological
- Vein diameter at multiple levels
- Status of perforator veins connecting superficial to deep system
- Patency of deep veins — rules out DVT or post-thrombotic damage
- Map of incompetent segments for treatment planning
How the Test is Performed
- You stand on a small platform — gravity loads the venous system.
- Warm gel is applied to the leg.
- The radiologist moves an ultrasound probe along the leg, usually 30–40 minutes for both legs.
- You will be asked to perform Valsalva (bear down) and have the calf gently squeezed — these manoeuvres provoke reflux for measurement.
- You receive a written report with diagrams and a CD/USB of recorded clips.
Cost & Where to Get It in India
| City Type | Typical Cost (Both Legs) |
|---|---|
| Tier 2/3 city diagnostic centre | ₹1,500–₹2,500 |
| Tier 1 city / corporate hospital | ₹2,500–₹4,500 |
| Specialist vein clinic (with treatment-grade reporting) | ₹2,000–₹3,500 |
At Dr. Raja's Vein Clinic, the Doppler is performed by the treating doctor himself — meaning the report directly translates into a precise treatment plan, not a generic "venous reflux noted" comment.
How to Prepare
- Drink plenty of water in the 24 hours before
- Do not apply any oil or cream on the legs that morning
- Wear loose clothing (shorts ideal) or be ready to change into a gown
- Carry any previous reports for comparison
- No fasting required; eat normally
Frequently Asked Questions
Is a varicose vein test painful?
No. It is completely painless. You will feel pressure from the probe and warm gel, nothing more.
How much does a Doppler test for varicose veins cost in India?
Typically ₹1,500–₹3,500 for both legs. Specialist vein-clinic Dopplers may cost slightly more but produce treatment-grade reports.
Do I need a doctor's referral for the test?
In most centres yes, but specialist vein clinics often perform Doppler as part of the initial consultation. Call ahead to confirm.
What happens after the test?
Your treating doctor reviews the Doppler findings together with the clinical examination, then advises whether you need conservative treatment (stockings + lifestyle) or a procedure (EVLA, RFA, MOCA, glue, foam).
