WebDVT patients with proximal clots had higher D-dimer levels (3760 vs. 1670 mg/dL) than with distal clots. Sensitivity and negative predictive value (NPV) for proximal DVT at an optimal D-dimer cutoff of 5770 mg/dL were 40.7% and 52.1% respectively. WebAs such, D-dimer levels correlate with the presence of fibrin clots. The assay can be falsely negative if the specimen is collected very early or later than 7 days of clot formation. Regardless, a negative assay should be able to safely rule out a large PE in low and moderate risk patients.
