D-dimer

In medicine, D-dimer is a fibrin degradation product.

Using D-dimer to determine duration of anticoagulation treatment
An abnormal D-dimer level at the end of treatment might signal the need for continued anticoagulation with warfarin among patients with embolism and thrombosis such as a first unprovoked pulmonary embolus. If the D-dimer is abnormal, anticoaguation should be continued, if the D-dimer is normal, the duration of treatment is uncertain. In an observation study that collected the[D-dimer before stopping anticoagulation, the D-dimer was not as predictive.
