General Information About the Test
Test Process and Preparation
The most valuable feature of the D-Dimer test is that it is 'exclusionary'. If the D-Dimer result is normal (negative) in a suspected patient, the probability of that patient having a large vascular clot is ruled out with an accuracy of over 95%.
No. Elevated D-Dimer is seen not only with blood clots but also during pregnancy, advanced age, trauma, recent surgeries, severe infections, and cancer. Imaging such as an ultrasound or CT scan is essential for a definitive diagnosis.
Since it is typically requested in emergency situations, fasting is not required. It is measured quickly in the laboratory using a tube of blood drawn from the arm.
