Doppler Ultrasound: Both Legs Doppler (Arterial )

Specimen Required

NONE

Fasting Required

Purpose of the Test

The test is used to assess the presence of any blockages or abnormalities in the arteries of the legs, which can indicate peripheral artery disease (PAD). PAD is a condition in which the arteries that supply blood to the legs and feet become narrowed or blocked, leading to reduced blood flow and oxygen delivery to these areas.

When this test is required

The test may be requested for patients who have symptoms of PAD, such as pain, cramping, or weakness in the legs, particularly during physical activity. It may also be ordered for patients with risk factors for PAD, such as those who smoke, have diabetes, high blood pressure, or high cholesterol levels.

What the Test Detects

The Both Legs Doppler (Arterial) Doppler Ultrasound is a diagnostic test used to evaluate the blood flow in the arteries of both legs.

Preparation for the Test

It is important to inform the healthcare provider if the patient has any medical conditions or is taking any medications that may affect the test results. The results of the test can help guide the physician in the diagnosis and treatment of any underlying conditions that may be present.

Sample Requirements

No specific sample is required for this test, and no special preparation is needed beforehand. However, patients should wear loose, comfortable clothing that allows easy access to the legs.

Additional Notes

It is important to inform the healthcare provider of any medications the patient is taking, as well as any other medical conditions, as these may affect the test results. Additionally, the patient should wear loose, comfortable clothing that provides easy access to the legs. The test is typically performed by a vascular technologist or sonographer, who applies a gel to the skin of the legs and then uses a handheld device called a transducer to emit sound waves that create images of the blood vessels in the legs. The test is non-invasive and painless, and typically takes less than an hour to complete.
