However, as with DVT, the Wells rule has been widely validated and commonly used for assigning a pretest probability of pulmonary embolism ( Table 3 ). 20.Likewise, a low pretest probability with a negative d -dimer assay result excludes the diagnosis of pulmonary embolism.It is warranted in patients who may have a pulmonary embolism and a positive d -dimer assay result, or in patients who have a high pre-test probability of pulmonary embolism, regardless of d -dimer assay result.
