The assessment of deep vein thrombosis (DVT) begins with the estimation of the pretest probability of DVT according to scoring systems such as the Wells score.  The initial<unk>  test for a suspected DVT is either D-dimer, proximal ultrasound, or whole leg ultrasound depending on the pretest probability of the disease. Further tests might be required depending on the findings of the initial test and the pretest probability of DVT.
