Specimen Required

NONE

Fasting Required

Purpose of the Test

A single-arm venous Doppler ultrasound is typically ordered by a healthcare provider when a patient shows signs or symptoms of a blood clot in the arm, such as swelling, pain, warmth, or redness. It is also used to monitor the effectiveness of treatment for DVT or to check for the development of new clots.

When this test is required

A healthcare provider may request a single-arm venous Doppler ultrasound when a patient presents with symptoms of DVT in the arm, such as swelling, pain, warmth, or redness. The test may also be ordered to monitor the effectiveness of treatment for DVT or to check for the development of new clots.

What the Test Detects

A single-arm venous Doppler ultrasound is a type of diagnostic imaging test that uses high-frequency sound waves to produce images of the veins in a single arm. The test is used to detect blood clots or deep vein thrombosis (DVT) in the arm.

Preparation for the Test

There is no special preparation needed for a single-arm venous Doppler ultrasound. Patients may be asked to wear loose-fitting clothing that allows easy access to the arm being examined. It is also important to inform the healthcare provider of any medications or supplements being taken, as some may interfere with the test.

Sample Requirements

No sample is required for a single-arm venous Doppler ultrasound. The test is a non-invasive imaging procedure that uses sound waves to produce images of the veins in the arm.

Additional Notes

A single-arm venous Doppler ultrasound is a non-invasive and painless test that typically takes between 15 and 30 minutes to complete. Patients may be asked to wear loose-fitting clothing that allows easy access to the arm being examined. In some cases, additional imaging tests, such as a contrast venography, may be needed to confirm the presence of a blood clot. It is important to follow the healthcare provider’s instructions regarding the preparation and scheduling of the test.
