About D-Dimer
D-Dimer rises when your body has recently broken down a blood clot, making it a useful marker for ruling out conditions like deep vein thrombosis or pulmonary embolism. A normal result is often more useful than an abnormal one, since it can rule out clotting concerns quickly.
No fasting is required, and given how urgent clotting concerns can be, results are available the same day.
How to Prepare
- No fasting required.
- No special preparation needed before your blood draw.
