In this study, we prospectively evaluated the Stratus DDMR D-dimer test in patients suspected of pulmonary embolism (PE) and deep vein thrombosis (DVT). Methods Patients suspected of venous thromboembolism were prospectively enrolled at four different clinical sites, with sodium citrate and lithium heparin plasma was tested using the DDMR D-dimer test on the Stratus CS analyzer. Results 1,012 patients were enrolled for analysis, with 85/603 (14.1%) patients with PE and 80/443 (18.1%) with DVT, and four of the patients (0.4%) with PE and DVT. For the samples …
