Print: How does my doctor diagnose DVT?
If your doctor thinks you might have DVT, he or she will perform some tests to find out. These may include an ultrasound (a test that uses sound waves to check the blood flow in your veins) or venography (a doctor injects dye into your vein, then takes an X-ray to look for blood clots).
