A Venous Doppler test is an ultrasound that uses sound waves to create a picture of your blood flow. The most common use of this test is to search for blood clots. It’s also commonly used for people with varicose veins.
Your doctor may order this test if you have leg pain or swelling, or if you have had a previous history of deep vein thrombosis (DVT). Left untreated, these blood clots can break off and pass into your lungs and potentially cause a pulmonary embolism.
Before your test
There is no specific preparation for this test. Please allow approximately 30–60 minutes for the test depending if one or both legs or arms require testing.
During the test
After the test
Your doctor will receive the results after a vascular physician interprets the study. During your follow-up appointment, your doctor will discuss your results with you. If the test is positive for a blood clot, the vascular technician will notify your physician and the vascular physician for treatment options.
