What is a D-dimer Test?

• D-dimer is a piece of protein left in the blood when a blood clot dissolves in the body.
• It is a marker of fibrinolytic activity and activation of the coagulation system.
• Higher levels of D-dimer indicate increased clot formation and breakdown.
• The D-dimer blood test helps determine the amount of D-dimer levels in the blood.

When is a D-dimer Test Used?

• When there is suspected clotting in the blood
• To help rule out DVT and PE in symptomatic patients.
• A negative result can help exclude a clot, while a positive result indicates the need for imaging tests.
• To monitor treatment response in patients with confirmed DVT/PE. Levels should decrease with effective anticoagulation therapy.
• To aid in the diagnosis of disseminated intravascular coagulation (DIC).
