DVT Test - what is it and how the test is done
When blood clots clog your blood vessels, you have thrombosis. Thrombosis is classified into two types:
· Venous thrombosis occurs when a blood clot obstructs a vein.
· Arterial thrombosis occurs when a blood clot obstructs an artery.
Your healthcare professional will assess your medical records and perform a physical examination. The tests include:
Ultrasound: This test involves sound waves to assess blood flow in your arteries and veins.
Blood Tests: These could include tests to determine how well your blood clots.
Venography: During this invasive test, your physician numbs the skin of your neck or groyne and inserts a catheter into your veins to determine if any blood clots are entirely or partially restricting blood flow. Venography is seldom being used now, but it can be required.
Magnetic Resonance Imaging (MRI) or Magnetic Resonance Venography (MRV): MRI scans the tissues and organs inside your body. MRV displays images of veins in particular areas of your body. MRI and MRV can provide more data than a duplex ultrasound or CT scan in certain circumstances.
Computed tomography (CT) scan: This test is an X-ray that reveals structures inside your body. Your physician may use a CT scan to detect a DVT in your belly, pelvis, or brain and blood clots in your lungs (pulmonary embolism).
