About this test

D-Dimer is a small protein fragment which remains in the blood when a blood clot degrades. A blood test for concentrations of D-Dimer is used to help diagnose thrombosis (a blood clotting disorder) – for example when deep vein thrombosis (DVT), pulmonary embolism (PE) or disseminated intravascular coagulation (DIC) is suspected.  A negative D-Dimer result indicates that a thrombotic condition is highly unlikely to be present. A raised result can indicate thrombosis but does not rule out other causes.  Further testing is usually required following a raised result to confirm a diagnosis of thrombosis.
