Safety of a Diagnostic Strategy With D-Dimer Testing for PE
To determine whether D-Dimer testing, using the MDA D-Dimer assay, can be used to simplify the diagnostic process for pulmonary embolism (PE). This will be assessed by performing a cohort study in 1000 patients with suspected PE.
To ascertain if an MDA D-Dimer result of less than 0.75 ug/mL FEU obviates the need for further testing and therapy in patients with suspected PE.
