ABSTRACT
Classic enzyme-linked immunosorbent assay (ELISA) D-dimer assays are sensitive in
screening for thromboembolic disease; however, they are cumbersome and time consuming
to perform, which limits their routine use. Latex agglutination assays are easier
to perform, but they are not as sensitive as the ELISA assays. New D-dimer assays
incorporating novel technologies can be performed rapidly with a sensitivity approaching
that of classic ELISA assays. D-dimer assays are uniformly sensitive in detecting
thromboembolic disease in different patient populations; however, low specificity
limits the clinical utility of D-dimer measurements in medical inpatients and postoperative
patients. Increasingly, these measurements are being incorporated into diagnostic
algorithms for venous thromboembolism and are reducing the need for invasive diagnostic
studies.
