D-dimer testing for deep venous thrombosis

D-dimer assay is a diagnostic test used to rule-out deep venous thrombosis (DVT). The D-dimer is a degraded fibrin protein that is  present in the blood after a thrombus (blood clot) has been degraded by fibrinolysis. The D-dimer concentration may be determined by a blood assay in conjunction with other diagnostics tests such as ultrasound and angiogram to diagnose thrombosis.
