Frequently Asked Questions (FAQs)
D-dimer reflects the presence of stabilized fibrin and this has made this marker a useful tool in the diagnosis of venous thromboembolism (VTE). This test is indicated for use in conjunction with a clinical pretest probability assessment model to exclude deep vein thrombosis (DVT) and pulmonary embolism (PE) disease in outpatients suspected of DVT or PE. D-dimer is not specific for DVT/PE and elevated levels are also observed in a variety of other conditions where activation of coagulation and fibrinolysis occurs (for example surgery trauma, infection, inflammation, pregnancy, cancer). Under certain conditions, lower than excepted D-dimer results may occur giving rise to false-negatives. Therefore it is not safe to use D-dimer for exclusion of DVT/PE in patients with high pre-test probability, long duration of DVT/PE symptoms (more than one week) or already under anticoagulant treatment.
