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. 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.

WebPlasma D-dimer levels are elevated in the presence of acute thrombosis because of simultaneous activation of coagulation and fibrinolysis [Konstantinides, 2014]. The negative predictive value of D-dimer testing is high, and a normal D-dimer level means that acute PE or DVT is unlikely. WebResults: A total of 759 extremely elevated D-dimer results were identified. After exclusion of 120 duplicate cases, 53 patients undergoing cardiopulmonary resuscitation, and 5 cases without diagnostic information, 581 cases were analysed.
