Quantitative D-dimer determination has become routine practice in patients evaluated for the presence of deep venous thrombosis or pulmonary emboli (1)(2)(3). D-Dimer concentrations below a certain cutoff specifically defined for each assay [500 µg/L for ELISA and comparable assays (3)] are considered sufficient evidence to exclude a deep venous thrombosis or pulmonary emboli if the pretest probability is low (4). In addition, D-dimer has been shown to be a reliable indicator of coagulation activation in disseminated intravascular coagulation (5) and malignancy (6). More recently, the relevance of the determination of D-dimer in arterial disease was evaluated (7), and it was shown that D-dimer is a very good predictor of recurrent acute coronary syndromes after a first event (8). There is also some indication that the amount of D-dimer generated correlates to some extent with the degree of atherosclerosis (9).
Fully quantitative D-dimer assays and their automation are recent
