The sensitivity and specificity of a red blood cell agglutination D-dimer assay for venous thromboembolism when performed on venous blood.

Abstract
D DIMER is a fibrin degradation product formed by the enzymatic activity of plasmin on cross-linked fibrin polymers. Plasma levels can be measured and are useful in patients who present with symptoms of pulmonary embolism (PE) or deep vein thrombosis (DVT),1,2 because negative test results (below a predefined cut point) rule out the likelihood of these diseases.
