Why do I need a D-dimer test?
You may need this test if you have symptoms of a blood clotting disorder, such as deep vein thrombosis (DVT) or a pulmonary embolism (PE).
Symptoms of DVT include:
Leg pain or tenderness
Leg swelling
Redness or red streaks on the legs
Symptoms of PE include:
Trouble breathing
Cough
Chest pain
Rapid heartbeat
This test is often done in an emergency room or other health care setting. If you have DVT symptoms and are not in a health care setting, call your health care provider. If you have symptoms of PE, call 911 or seek immediate medical attention.
