Clinical Significance
D-Dimer is one of the measurable by-products of activation of the fibrinolytic system. Quantitation of D-Dimer assesses fibrinolytic activation and intravascular thrombosis. D-Dimer is of particular value in excluding the diagnosis of venous thromboembolism among patients at high risk.
