D-dimer assays should not guide angiography avoidance in suspected PE; leaves open the need for higher-specificity exclusion strategies.
Do D-dimer assays reduce the need for angiography in patients with clinically suspected pulmonary embolism?
Latex D-dimer assays are not useful and ELISA methods have limited value for excluding pulmonary embolism to avoid angiography in this cohort.
Beek et al. (1993) studied this question.
