A rapid quantitative ELISA for measuring D-dimer to exclude pulmonary embolism

Objective To study VIDAS D Dimer whether this new assay fulfill the requirements for diagnostic exclusion in patients suspected of pulmonary embolism. Methods Plasma D dimer of clinically suspected pulmonary embolism patients were measured by VIDAS D Dimer, three month after their inclusion all patients were confirmed to know if they had any new symptoms suggestive of deep vein thrombosis or pulmonary embolism. Results Among 104 suspected pulmonary embolism patients, 32 patients (30.8%) with DD levels 494 ng/ml and 72 patients with DD levels 494 ng/ml. 16 patients were confirmed with pulmonary embolism by V/Q scan , everyone of them with DD levels 494 ng/ml. The test showed a sensitivity of 100%, a negative predictive vale of 100%. Conclusion VIDAS D dimer is well sited as diagnostic tool for the exclusion pulmonary embolism.
