Is there anything else I need to know about a D-dimer test?
If your D-dimer test results were not normal, your provider may order one or more imaging tests to find out if you have a clotting disorder. These include:
Doppler ultrasound, a test that uses sound waves to create images of your veins.
CT angiography. In this test, you are injected with a special dye that helps your blood vessels show up on a special type of x-ray machine.
Ventilation-perfusion (V/Q) scan. These are two tests that may be done separately or together. They both use small amounts of radioactive substances to help a scanning machine see how well air and blood move through your lungs.
