Web1 aug. 2013 · Purpose: To estimate should D-dimer testing during anticoagulant therapy be used to indicate VTE pts who need extended anticoagulant therapy. Methods: One hundred and eleven pts (76 men) in the age 18-76 (mean 54±14) years with deep vein thrombosis (DVT) and/or pulmonary embolism (PE) were included in the study. WebThe mean D-dimer value was 2104±1394 ng/mL in the 34/34 PE+ children and 586±962 ng/mL in PE- children with a sensitivity of 34/34 (100%, 89% to 100%) and a specificity of 290/492 (58%, 54% to 63%). The area under the receiver operating characteristic curve was 0.90 ((0.9)87-0.94).

WebA higher than normal D-dimer level might mean you have had a significant blood clot. However, the test does not tell where the clot was or what caused it. Other health problems can also cause the D-dimer level to go up. Therefore, the D-dimer test is not the only test used to diagnose a disease or condition. WebD-dimer is a multifaceted biomarker of concomitant activation of coagulation and fibrinolysis, which is routinely used for ruling out pulmonary embolism (PE) and/or deep vein thrombosis (DVT)...
WebCheck your local institutions guidelines. Most contemporary laboratories use high sensitivity assays. D-dimer can be reported as fibrinogen equivalent units (FEU) or d-dimer units (DDU). One DDU = 2 FEU. The reporting units used will affect the cut-off. The standard cut-off for venous thromboembolism is 0.5mg/L FEU or 0.25mg/L DDU. WebD-dimer assays demonstrated high sensitivity in all four studies, but with high levels of false-positive results, especially among those over the age of 65 years. Estimates of sensitivity ranged from 80% to 100%, and estimates of specificity from 23% to 63%.
